The practice of using SIP (Structural Insulated Panel) panels as the main building material is not only widespread in the countries of the West and far abroad, but at the same time is rapidly developing and finds widespread use in our country.
Why should you give your preference to SIP panels?
Sip panel composition
The panels are special structures made of a wooden bar and two oriented strand board (OSB) attached to it, the inner space between which is filled with expanded polystyrene. The resulting layers are glued together with one-component polyurethane-based glue.
The slabs are assembled in such a way that it is easy to use the “tongue-and-groove” system.
erected using this kind of panels, first of all, are distinguished by their low specific gravity, thereby significantly reducing the load on soil soils and the requirements for the foundation, respectively. In addition, significant, erected using this technology, is the highest level of strength and reliability. Thus, the panels are capable of withstanding a load in the vertical direction up to 10 tons, and in the transverse direction - up to 2 tons throughout the entire operational period, which exceeds 80 years. In addition, in the shortest possible time, generally not exceeding a 3-month period.
Excellent sound and heat insulation characteristics, complete fire safety and an absolute level of environmental friendliness - all these qualities determine the success of SIP panels.
In addition, SIP panels, with proper adherence to technology and the use of proven materials, can be produced with your own hands at home, further reducing their cost.
Tools and materials used in the production of SIP panels
Insulation of Sip-panels The materials and equipment used in the process of manufacturing sandwich panels are:
- Oriented strand board OSB-3;
- Expanded polystyrene or other insulation;
- Wooden beam;
- One-component polyurethane-based adhesive. Oriented strand boards (OSB) are panels with a thickness of 10-12 mm and are the result of pressing wood shavings no more than 1.5 cm long and no less than 0.6 mm in diameter under the influence of high temperature using specialized resins. Chips are usually stacked in 3 layers perpendicular to each other. Such material is easily sawn, drilled and holds any fastening material.
- universal insulation raw material, consisting of expanded polystyrene. In the process of manufacturing sandwich panels, polystyrene foam of S-25-35 grades is usually used. This material is 95% carbon dioxide and differs not only in its low weight, but also in its low cost compared to other heaters.
As an adhesive, compounds such as, for example, Kleyberite 502.8, top-level 15, Macroplast UR 7228 and Macroplast UR 7229 are used. Special requirements are imposed on such compositions: an increased level of moisture resistance, a wide temperature range (from -40 to +50 degrees Celsius), possessing absolute environmental friendliness and corresponding to the long service life of the panel.
The working surface should be a table that is larger than the OSB-3 sheet, and as a means of applying the adhesive, either a special sprayer or a device made of a canister and a rubber spatula with teeth can be used.
In addition, you will need a sandwich panel pressing machine. The press will cope with this task, or, if there is none, a powerful vacuum pump is used, with the help of which the necessary result is achieved.
For the manufacture of panels, you also need a thermal knife or a thermal cutter. This device is a heating element on the handle that heats up from the network; it is necessary to melt the insulation. With the help of a knife, SIP panels are cut into pieces.
SIP panels production
Vacuum press for SIP panels How to make a sip panel? The OSB-3 sheet is laid on a flat work surface (special table), and glue is applied to it using a spray gun, glue, brush, roller, spatula with teeth or any other device. As a rule, the consumption of the adhesive is 150-200 gr. for each square meter, but, in turn, it strongly depends on the method of application. The composition is kept for 8-10 minutes, after which expanded polystyrene of C-25-35 grades is placed.
In the process of making sandwich panels with your own hands, the speed of the actions performed plays a special role. Do not allow the adhesive to polymerize between layers. Otherwise, the resulting structure will have a low level of strength and reliability; such a panel cannot be used in further construction.
The laid sheet of expanded polystyrene is carefully leveled, a uniform layer of adhesive is applied to it. On top of the insulation, the next layer is laid, consisting of an OSB panel. Next, the second plate is formed according to the above algorithm.
It is necessary to assemble the panels at least 5, and you should also take care of the need to exert pressure on them. For this purpose, the technique of vacuum pressing is used. The pre-aligned stack of panels is covered with a cover made of awning fabric, glued together with a special adhesive, for example, "Cosmofen SA-12". Preliminarily clamping the edges or ensuring the proper level of tightness using any other method, air is pumped out from under the cover. Look at the photo above, where the panels are under a vacuum press.
Thus, there is a significant pressure on the panel of the order of 1 ton per square meter. The holding time under vacuum is 40-60 minutes, after which the next “stack” of panels can be produced.
For 8 hours of continuous work, about 25-35 sandwich panels can be glued. It is worth noting that ready-made slabs must remain in a horizontal position for at least a day in order to finally acquire the expected performance characteristics.
Compliance with safety during production
Applying glue to the base for gluing insulation As in any production process, safety in the production of sandwich panels plays an important and far from the least role. So, all work should be carried out in a spacious, well-lit and ventilated room. All work with sandwich panels is carried out in special clothes with long sleeves, hands are protected with gloves, eyes, and, if necessary, goggles.
How profitable is manual panel production?
Manual production implies the following cost items:
- Glue;
- OSB-3 sheets;
- Expanded polystyrene;
- Vacuum pump for air evacuation;
So, for example, 100 panels, we need:
200 sheets of OSB-3, 500 rubles each. each - 100 thousand rubles;
from a consumption of 2 kg. glue (average price per kg. 150 rubles) per sheet - about 40 thousand rubles;
vacuum pump - 15 thousand rubles;
expanded polystyrene from a consumption of 0.5 cubic meters. m per panel - 90 thousand rubles Compared to industrial panels, manual production allows you to save at least 100 thousand rubles, which is important in current conditions. The cost of the plate is 1300 rubles per square meter. In general, the price depends on the thickness of the plate.

The construction of houses from SIP panels in Western Europe and far abroad is a fairly common technology. And the pace of construction of buildings from SIP panels in our country is constantly increasing. This technology is popular due to the speed of building a house with high performance characteristics. Many private developers choose frame housing technology because of its simplicity and the possibility of self-construction of a home. But if the frame can be built with your own hands, then the panels are finished factory products. In this regard, the question arises of how to make a self-supporting insulated wire panel with your own hands, so that when building a house yourself, you have all the building materials for a frame structure.
Benefits of SIP panels
The panel construction includes the following details:
- frame made of wooden beams;
- the entire structure is closed on both sides with oriented strand boards, which are glued with a one-component polyurethane-based adhesive.
All slabs are made in such a way that they are hermetically connected to each other due to the thorn-groove lock. The house made from these panels and the slabs themselves have the following advantages:
- Due to the small specific gravity of the material, the entire building is quite light, so a lightweight shallow foundation can be erected under such a house. As a result, you will be able to save on materials, the volume of earthworks and reduce the construction time.
- Structures built using frame-panel technology are durable and reliable.
- The panels can withstand significant loads. In the vertical direction, these loads can reach up to 10 tons, and in the horizontal direction, the structure can easily withstand a load of 2 tons. Moreover, these strength characteristics of the elements do not decrease throughout the entire service life.
- The service life of a house made of this material is 80 years.
- The speed of construction. It usually takes up to 3 months to build a small private house.
- The material has excellent heat and sound insulation characteristics.
- The panels are fireproof.
- These products are environmentally friendly and completely harmless to humans.
- The technology for manufacturing SIP panels is so simple and affordable that you can make such products yourself. As a result, you can significantly save on materials for building a house.
Important: the independent production of high-quality SIP plates is possible only with strict adherence to the assembly technology.
Materials and tools used for production
To make a CIP panel with your own hands, you will need the following materials:
- OSB-3 is oriented strand board;
- timber (it will be needed for the construction of the frame of the house, and not for the manufacture of wall plates);
- one-component polyurethane-based adhesive;
- expanded polystyrene or any other heat-insulating material.
Attention: it is recommended to use extruded polystyrene foam for insulation of boards due to its high efficiency. Choosing other materials with lower thermal insulation qualities, you will have to increase the thickness of the insulation, and, consequently, the thickness of the panels themselves.
OSB-3 is a slab 1-1.2 cm thick. They are made in the process of pressing chips, the dimensions of which do not exceed 1.5 cm in length and 0.6 mm in diameter. The material is mixed with special resins and pressed at high temperatures. The chips are pressed in several layers, with the direction of the fibers in all layers directly perpendicular to each other. OSB is easy to process, any fasteners are securely fixed in them.
For the manufacture of sandwich panels, it is better to use expanded polystyrene brand C-25-35. This material is made from expanded polystyrene. It contains 95% carbon dioxide. The specific gravity of this material is small, and the cost is quite acceptable.
To build your home with your own sandwich boards, you will need one of the following adhesives:
- Top-ur modification 15;
- Kleyberite grade 502.8;
- Macroplast UR 7228 series;
- Macroplast series UR 7229.
The following requirements are imposed on the adhesives used:
- They must have a sufficient degree of moisture resistance.
- The adhesive can be used in the temperature range from -40 ° C to + 50 ° C.
- No less important is the harmlessness and absence of toxicity of the used glue for humans and the environment.
- The adhesive connection must be quite reliable and durable in order to meet the declared life of the house.
In addition, the following tools will come in handy:
- For the manufacture of panels, it is better to prepare a work surface, for example, a table, the dimensions of which are slightly larger than the dimensions of one oriented strand board.
- The adhesive can be applied using a spray gun, brush, or notched trowel.
- The most important equipment is the board pressing machine. Instead, you can use a conventional press or powerful vacuum pumping equipment.
- You will also need a heat cutter or thermal knife. These products have a special heating element that heats up from the electrical network. The product will be needed to cut the insulating material into separate parts.
Benefits of self-made panels
As you can see, for self-production of SIP-plates, you will not need so many materials and tools. Your biggest expenses will be from buying glue, insulation, OSB, vacuum pump or press. As a result, you will get an insulated, warm and durable house at an affordable price.
- $ 1,500 you will spend on the purchase of 200 sheets of OSB-3, each of which costs 7.5 cu;
- 630 USD for glue at the rate of 2 kg of adhesive per sheet (the cost of 1 kg of glue is 2.3 cu);
- 1400 USD for heat-insulating material, while one panel will need 0.5 m³ of insulation.
The cost price of one panel will be 20.5 USD / m². The price may vary slightly depending on the thickness of the item, but overall you will get savings of $ 1,500.
Manufacturing technology
If you want to make wall plates for a frame house yourself, then you should adhere to the following sequence of actions:
- OSB is laid on the work surface. Using any tool for applying glue, it is coated with glue over the entire plane. As a rule, the consumption of glue depends on the method of application, but on average, it takes from 150 to 200 grams per square meter. glue.
- After 8-10 minutes, a sheet of expanded polystyrene is laid on the applied glue.
Attention: in order to prevent the glue from hardening, it is worth adhering to a certain speed of performing operations when making self-supporting SIP panels.
- After leveling the expanded polystyrene sheet, an adhesive composition is applied to it.
- Then, without waiting for the glue to harden, the second layer of OSB is laid.
- Five more panels are made in the same way, since it is better to subject several products at once to the pressing process.
- All prepared panels are stacked one on top of the other. They are covered with a cover made of thick awning material. The cover can be made by yourself by gluing the material blanks using the Cosmofen SA-12 series glue.
- Further, the open edge of the cover must be tightly wrapped, fastened or sealed in another way. After that, air is pumped out of the cover. As a result, a pressure of about 1 t / m² is exerted on the products.
- The panels must be kept under vacuum for 40-60 minutes. After that, you can start making the next batch.
- Finished products should lie in a horizontal position for at least 24 hours. During this time, they will gain the necessary performance characteristics.
Important: if the work is carried out continuously, then in 8 hours you can independently make 25-35 wall products for a frame house.
Safety engineering
To ensure that your health does not suffer during the production of plates, you need to observe the following safety rules:
- It is worth using personal protective equipment. So, you will need long-sleeved clothing, special goggles and hand gloves.
- If the ventilation of the room is insufficient, then you should additionally use a respirator. This way, you don't have to inhale the evaporating adhesive.
Making SIP panels using a press with your own hands - video:
The domestic construction sector has undergone significant changes in recent years under the influence of the global market. In particular, this applies to technologies for the construction of private houses. Particularly in demand have become Canadian building ideas, involving the rapid construction of strong, environmentally friendly and energy efficient houses. Along with this, the production of SIP panels is also developing, which act as the main material for such buildings. The manufacturing technology is not only distinguished by high profitability, but also, in general, allows you to get a decent result in the form of a modern residential building.
What is a SIP panel?
In essence, this is a kind of wood-shaving building material. It must be said that the segment of multilayer panels, apart from Canadian technologies, is quite popular these days, as it allows you to quickly implement a project with minimal costs. Also, the interest from the consumer is stimulated by the relatively high technical and operational indicators of the material, which, in turn, motivates the business. The production of SIP panels is distinguished precisely by the orientation towards the popular technology. These are three-layer structural sheets, which also have high-quality external insulation.
Traditionally, frame houses have won due to the high speed of construction and affordable prices, however, in terms of high-quality operational parameters, they were noticeably inferior to classic log cabins. SIP panels solved this problem by improving the physical characteristics of the material. In practice, this improvement is reflected in strength, resistance to weathering and mechanical stress.
Manufacturing technology
It is clear that high technical and physical characteristics are achieved in the course of a complex process of processing raw materials. The complete technological cycle involves the implementation of three main stages - assembly, cutting and gluing. The first two stages of production are carried out on the center line, and the third on separate equipment. Assembly activities, in turn, involve a combination of expanded polystyrene sheets, OSB and PSB boards. In parallel with this, the workpieces are trimmed in accordance with the originally conceived dimensions. After that, the final stage begins, in which polyurethane or other glue is used, which provides for the Canadian production of SIP panels in its regulations. The technology also allows the possibility of simultaneous gluing of several panels, but this already depends on the capacity of a particular workshop. Physically, this process is carried out by pressing machines that provide a load of about 5 tons.
Raw materials for panels
In accordance with the requirements of the technology, the basic set of the raw material base should include oriented strand boards and non-shrinking suspension polystyrene foam sheets. A polyurethane compound is used as a binder. However, it is the glue base that is the most controversial ingredient in this set. The fact is that the production of SIP panels endows the final product with the necessary margin of safety, but environmental friendliness is still being questioned. Today, new adhesives are being developed that can provide a high bonding function, but at the same time will have less harmful effects. Perhaps the emergence of a new and cleaner glue will give a new impetus to the development of technology.
Equipment for the production of SIP panels
There are two approaches to organizing a production line for SIP panels. In the first case, it is planned to install a fully equipped complex with all the necessary units for the manufacture of building materials. Such a mini-workshop includes feeding communication units, a pressing machine, a cutting station, etc. The cost of finished lines varies from 2 to 3 million rubles. Of course, this option is more likely to suit enterprises that already have the opportunity to set up a new conveyor. If it is planned to organize a small private line, then it makes sense to equip the separate production of SIP panels. in this case it is more promising and retains all the possibilities for further expansion. Anyone wishing to organize such a workshop will need a small room in which it will be possible to install a cutting machine, a press and a thermal knife.
Financial investments
Equipment can become the main expense item. In the case of purchasing a finished workshop, the costs will average 2.5 million, and if we are talking about self-assembly, then we can talk about 200-300 thousand.Of course, in addition to this, you should add the costs of auxiliary devices, rent, regular purchase of raw materials and maintenance. These points will also spend about 50-70 thousand per month. However, the production of SIP panels quickly pays off these investments, since one unit of material brings on average a profit of 1,000. Depending on the productivity, the investments can be recouped either in a few months or in a year.
Distribution channels for material
The basis of the client base can be made up of private construction firms that are engaged in the construction of wooden houses. This segment is still in demand on the Russian market, and the fashion for Canadian technologies has only expanded the range of services of such enterprises. Also, the production of SIP panels can be focused on supplying individual developers who plan to independently implement projects. As practice shows, the possibility of direct interaction with a manufacturer of building materials gives a great advantage for consumers of different levels.
Conclusion
Although stone and brick houses are still associated with quality, durability and reliability to this day, alternative construction technologies pose serious competition for them. If comparisons in terms of strength do not always count towards panel-frame technologies, then affordability and energy efficiency are indisputable advantages that houses from SIP panels have. The production of this building material is largely focused on Canadian standards, but more and more Russian modifications of the technological process appear. A departure from the classic idea is associated with differences in the characteristics of wood materials. Russian forestry makes it possible to use a high-quality raw material base, which in some respects outperforms North American products.
The Russian construction industry has changed noticeably recently due to the influence of the world market. This also applies to technologies for the construction of private houses. Canadian construction ideas have gained popularity, according to which reliable and durable objects are being erected. With this area, the production of SIP panels is being improved. The method of building houses becomes profitable, thanks to which an excellent result is obtained. Business will be profitable in this area.
Definition
SIP-panels - wood-shaving building material. It should be borne in mind that it is in great demand at the present time, since it helps to build houses at low cost. Consumers are interested in products because of the high technical and operational performance of the material, which makes the business profitable.
The production of SIP panels is in demand because the products are used in panel-frame construction. These sheets allow for high-quality insulation. Classic frame houses were popular due to their speed of construction and affordable cost, but in terms of performance, they are lower than traditional log cabins. The production of SIP panels solves this problem. A business from scratch in this area provides a stable income. Such materials are resistant to various loads.
Manufacturing technique
Naturally, excellent characteristics appear after a complex raw material processing procedure. The whole process involves the implementation of 3 main stages:
- assembly;
- cutting;
- gluing.
The first 2 stages of creation are carried out on the central line, and the third - on special equipment. The assembly procedure involves a combination of expanded polystyrene sheets, OSB and PSB boards. At the same time, the workpieces are trimmed based on predetermined dimensions.
At the end, polyurethane or another type of glue is applied, which is provided by Canadian technologies for creating SIP panels. Several products can be glued together, but everything is determined by the capacity of the workshop. This work is carried out by pressing machines with a load of about 5 tons. This is the production of SIP panels.
Raw materials
According to the requirements for the manufacture of materials, oriented strand boards and non-shrinking suspension expanded polystyrene sheets are required. The binder is a polyurethane compound. The adhesive base is considered one of the important components in the kit. Such production of SIP panels allows you to create a durable material, but hardly anyone would believe that it is environmentally friendly. Nowadays, new adhesives are being produced, thanks to which a high bonding function is provided, but no less harmful. Most likely, with the development of a new adhesive, new directions in the technology of panel manufacturing will appear.
Equipment
There are 2 options for organizing the production of materials. The first method involves the installation of a complex, where there is the necessary equipment for the production of SIP panels. Such a mini-workshop consists of:
- communication nodes;
- pressing machine;
- cutting point.
The price of the finished line is in the range of 2-3 million rubles. This option is ideal for businesses looking to install a new container. The plant for the production of SIP panels will work smoothly and, therefore, will bring a stable income. From there, materials will be delivered to stores and construction markets. To open a small private line, separate production of SIP panels is needed. Business in this case is more promising. In the future, you can think about expanding. To create such a workshop, a small room is needed to accommodate a cutting machine, a press and a thermal knife.
Premises
There are no strict requirements for the workshop where the panels will be manufactured. It includes several sections:
- area for storing raw materials;
- main production area;
- a place for drying the material;
- warehouse for storing panels;
- additional premises.
Each room must be equipped on the basis of sanitary and hygienic standards. Ventilation is required as the adhesive releases volatile components. Communication should be standard.
Material investments
Most of the costs will go towards purchasing equipment. If a ready-made workshop is bought, then about 2.5 million rubles will be required. Self-assembly costs between 200-300 thousand rubles. You also need to spend money on assistive devices, rent, purchase of raw materials and maintenance. All this takes about 50-70 thousand a month.
The production of materials quickly pays off, since the production of houses from SIP panels is considered a popular industry. The cost of 1 unit of the product is 1,000 rubles. How the payback occurs depends on performance. Sometimes it takes a couple of months, and in some cases, a year.
Additional expenses
If production is organized from scratch, then costs are required for:
- company registration;
- hiring workers;
- passing checks;
- purchase of fire and burglar alarms.
The ultimate payback rates depend on various factors. This is influenced by the cost of raw materials. The press can have different speeds. Production also depends on the glue used, manual labor.
Mini-workshop profitability
If you organize the production correctly, you will get a very profitable enterprise. To open a workshop will require at least 1 million rubles. The costs include registration of an individual entrepreneur, since everything must be legalized.
It will be possible to save money if you buy cheaper equipment. In practice, the creation of panels brings a stable income in the event that sales are established. For a mini-workshop, it will be enough to produce up to 5 sq. m of products per hour. If every day it takes 12 hours to work, then you can get up to 800 thousand rubles from the products sold, and the net profit will be at least 100,000.
Sales of materials
The main clients will be construction companies that carry out the construction of wooden houses. This area is still in demand on the Russian market. And the prevalence of Canadian technologies has only increased the list of services provided by such enterprises. The buyers of SIP panels will be individual developers planning to independently implement projects. As can be seen from practice, direct interaction with a manufacturer of building materials provides many benefits for consumers.
Output
While stone and brick objects still symbolize quality, durability and reliability, many other technologies remain in competition for them. If panel-frame technologies can be inferior in strength, then their cost and energy efficiency are considered an advantage.
The manufacture of this building material is carried out according to Canadian standards, but Russian versions of the technology still appear. The change in the classic idea is related to the characteristics of wood-based materials. In Russian forestry, high-quality raw materials are used, which in some properties are better than foreign ones.
SIP, SIP, sandwich panel - these are the names of one building material that is used in the construction of houses. SIP-panel is a three-layer block, both outer layers are made of OSB or chipboard sheets, between them a layer of polystyrene. High thermal insulation performance, ease of installation, low cost - make the business of manufacturing these materials attractive. All that is required to start production is an automatic line for the production of sip materials, raw materials, a few workers and a room. The presence of a high level of demand for such panels suggests a quick return on investment.
Required raw materials
For the manufacture of sandwich panels, various sheet materials can be used:
For the inner layer, the following can be used:
- polystyrene;
- polyurethane foam;
- mineral wool.
But the classic option is a combination of OSB and polystyrene sheets, the layers are connected to each other with glue.
Table of material consumption and its cost for the manufacture of one SIP-panel 2500 * 1250 * 174 mm (L * W * H).
Requirements for the production workshop
The room in which the line for the production of vulture panels will be located should be more than 200 m 2; it is also necessary to equip a warehouse for raw materials and finished products. If the area is small, you can save on the warehouse for finished products - you can store it outdoors, but only organize a canopy that protects it from rain and snow. It would be expedient to place management personnel near the production facility; they will require a non-production area of 30 m 2. The workshop must have three-phase electricity, water supply and sewerage are optional. It is necessary to control the temperature - not to allow a decrease to -15 o C. If you rent a room, the monthly costs will be 40 thousand rubles (rent and utility bills).
Service staff
To organize the work of the line for the production of vulture materials, four people will be needed, with an average output of 100 panels per shift. If a larger volume is planned, additional workers will be required accordingly. Management staff - director, purchasing and sales manager, accountant. The monthly wage fund will be 120 thousand rubles.
Equipment for the production of
There are various types of lines for the production of vulture panels, they differ in technical characteristics, the principle of operation is the same for all. The line for the production of 100 panels per shift has the following components:
Line for the production of SIP panels from mineral wool - mechanism for applying glue and pressing;
- a device for cutting foam;
- device for cutting panels;
- milling machine.
The glue applicator can be fully automated or manually operated. Automated spares glue, applies more evenly, speed can be adjusted. Specifications:
The device for cutting foam plastic cuts the raw material in accordance with the specified parameters. The mechanism is a frame and two moving portals on which cutting nichrome threads are fixed. The geared motor drives the portals, and the tension cable drives the threads. Cutting is carried out with incandescent threads up to 0.8 mm in diameter. Specifications:
The device for cutting SIP panels is designed for cutting finished products in accordance with the required parameters. Cutting is carried out on the frame with a circular saw operating at high speeds using an electric motor. Specifications:
A milling machine is necessary to form the groove of the SIP panel, with the help of which the elements will be attached to each other. The size of the groove can be specified by the customer individually for a separate project. Specifications:
- power - 2.2 kW;
- voltage - 380 V;
- milling depth - up to 60 mm;
- dimensions - 1200 * 3000 * 1200 mm;
- weight - 250 kg;
- cost - 93 thousand rubles.
Thus, the price of the line for the production of vulture panels can be 662 thousand rubles.
Technological process
The process of manufacturing SIP panels Manufacturing technology of SIP panels is quite simple. At the first stage, the panels are assembled. The OSB sheet is laid on a pressing machine, a layer of glue is applied to it, a layer of polyurethane foam is placed on top, and again a layer of glue, then water is sprayed so that the glue is better saturated, and the OSB sheet is fixed to the structure. At the next stage, the workpieces are glued under the press.
The pressing unit can be part of the glue application unit. In order to save money, you can complete the line for the production of sip panels with an inexpensive glue applicator. A manual spray gun costs 4,500 rubles, while its performance will be at a high level - 20 - 30 seconds applying glue to one side. A screw press will cost 79 thousand rubles. But it should be borne in mind that these two machines will require more manual labor, and will increase the consumption of materials due to losses and rejects. In general, the bonding stage is carried out in 20 minutes, the duration of the process will ensure a more tight fit of the sheets and their bonding together.
The final stage is the cutting of the panels. With the help of special cutting and milling equipment, the finished material is given the necessary shape, dimensions, cutouts are made for fittings, doors, windows. This process is carried out according to the individual plan of the customer.
Profitability of SIP-panels production
The profitability of production represents the value of the ratio of profit to costs.
2,200 panels will be produced per month (100 per shift * 22 working days).
The cost of manufacturing products per month will be:
- source materials - 2428 * 100 * 22 = 5 341 600 rubles;
- salary - 120,000 rubles;
- rent of premises and utility bills - 40,000 rubles;
- transportation and other expenses - 20,000 rubles;
- total cost - 5,521,600 rubles.
The market value of one plate will be 2,900 rubles.
Revenue per month - 2900 * 100 * 22 = 6 380 000 rubles.
Profit - 858,400 rubles.
Unaccounted for administrative expenses, taxes, the advance cost of raw materials for the next production cycle should be deducted from the profit. Partially cover the cost of the equipment at the expense of the remaining amount. The production profitability will be 40%, with the full implementation of the produced panels, you can recoup the cost of the line for the production of vulture modules within six months.
