The demand for plastic windows today does not surprise anyone; any construction of both residential and industrial facilities uses metal-plastic structures. In addition, an increasing number of people want to replace their old windows with new, more beautiful and reliable ones. Therefore, organizing a business in this industry will be very successful. The main component of this business is an automated line for the production of plastic windows, because in-house production will allow you to gain advantages over intermediary companies that sell products of leading brands, but waste time waiting for their turn in production.
Start of activity
A room for assembling plastic window parts
To start production, it is necessary to establish an enterprise, obtain tax and state registration, conduct tests and obtain quality certificates. Tests for compliance with GOST standards, SNiP requirements, as well as for obtaining foreign quality standards - DIN and RAL. Having as many certificates as possible, you can profitably establish yourself in the market of metal-plastic products. Before starting production and sales, a sanitary and epidemiological conclusion must be obtained; without it, sales will be impossible.
Preparation of production areas
Plastic windows and double-glazed windows
To organize a small business with an average productivity of up to twenty structures per shift, you will need a room with an area of at least 200 m2, and take into account the ceiling height - above three meters. A line for the production of PVC windows will be located here. Next to the production workshop there should be premises for storing finished products and raw materials. An administrative building will also be needed to house management personnel. For uninterrupted operation of the line, electricity is required; the voltage in the sockets must be at least 380 V. The workshop must be equipped with an air conditioning system, maintaining the temperature within 18-20 oC. If the temperature regime is violated, the technological process may fail, which will negatively affect the quality of the finished product. Provide in the room not only general, but also local lighting in some areas of the automatic PVC window production line. If it is not possible to purchase production space, you can use rent. Approximate rental costs per month will be 50 thousand rubles, utility bills - 25 thousand rubles.
Service staff
One person is enough to assemble a window.
Six people will be required to work on the production line, plus one more storekeeper to receive finished products and issue raw materials. Production cannot be done without an engineer who can quickly troubleshoot equipment problems, as well as a chief technologist who will monitor the manufacturing process and the quality of finished products. Labor costs can amount to 100 thousand rubles.

Technological process
Cutting PVC profiles
The production process of metal-plastic windows begins with cutting the profile in accordance with the required dimensions; they are calculated individually for each type of structure. Different types of buildings have individual window opening sizes, so profiles will be made in accordance with the parameters specified in the order. Having purchased a PVC window production line and started the production process, you should understand that this will be work for the customer, and not the production of template windows.
The next stage of production will be milling the frame for drainage channels, which will compensate for wind pressure and remove excess moisture.
After processing the metal profile, it is fixed in the plastic profile using self-tapping screws. An automatic screwdriver or a manual screwdriver is used here.
Then comes the process of milling the frame for installation of fittings; it is performed on a copy-milling machine.
When the metal-plastic elements are prepared, it is necessary to connect them into a solid frame, this happens using a welding machine. At this stage, it is better to use an automatic welding unit, since it is important to comply with the temperature conditions and heating time of the seam.
Milling a plastic frame
And before starting welding, you should remove dust and shavings from the surface of the frame, since contamination can reduce the quality of welding and affect the finished result.
The price of a line for the production of plastic windows includes a cleaning unit; it is used after the welding process to remove plastic deposits at the joints of the profile.
It is necessary to insert a sealing rubber into the finished frame, which is attached with glue. This process is completely manual.
The assembly of the metal-plastic structure takes place on a glazing stand. Here a double-glazed window, the necessary fittings, seam inserts, and gaskets are inserted into the profile. At this point, the technological process is completed; all that remains is to check the finished product for the functioning of all systems - this is a task for the chief technologist. The windows are ready for sale and subsequent installation.

The glass washing machine is used for efficient horizontal washing and drying of glass and is used at the preparatory stage of insulating glass production to ensure the cleanliness of the glass surface. The frame for fastening the glass is located horizontally. Sequential feeding, washing, drying and removal of glass is performed automatically. The processing speed is smooth. The equipment is reliable and easy to set up.
Water supply is implemented in a closed cycle. Water is supplied from a tank built into the unit. The first supply circuit is brushes, the second is washing the glass after the brushes. After the washing process, water collides with the surface of the glass by two pairs of squeezing rollers made of dense porous material. This device allows you to use harder water without compromising the quality of glass cleaning. No detergents are used. The water must be changed every two days or when the slightest stains form on the glass. Once a month you need to wash the squeezing rollers.
- The machine is equipped with a high-quality smoothness control device; the processing speed is adjusted by the operator, which ensures high quality washing.
- When washing glass, water from two tanks is used. This ensures a high degree of glass cleaning.
- The machine uses a two-stage water circulation system that separates clean and cloudy water, which saves water consumption.
- All parts of the glass cleaning and installation system (including the warm air supply pipe, temperature sensors, pipes, tanks, etc.) are made of high-quality stainless steel. The anti-corrosion coating prevents clogging of the water circulation system and the formation of rust.
- Four brushes, which are pressed tightly against the glass surface during processing, provide high quality cleaning.
- The machine is equipped with three absorbent rollers made of high-quality polymer, which ensures their excellent absorbency and long service life.
- The machine is equipped with a roller made of special rubber, which has high wear resistance, long service life and good processing quality.

Production of PVC window sills
PVC window sill
It is advisable to produce window sills along with windows, since the cost of a line for the production of PVC window sills is low. The line is an extruder complex, which includes molds, a slitting mechanism, and a laminating unit. The line may include a more complex design for the production of PVC itself, but for a small enterprise with a maximum load of up to 20 windows per shift, it is not needed. The finished material can be purchased from large industrial enterprises and cut independently according to the required dimensions. The cost of such a line will be 150 thousand rubles.
Profitability of production of metal-plastic windows
Plastic windows are installed in all new buildings or renovation houses.
The costs of organizing a business can be divided into capital and current.
Capital costs include the price of a line for the production of double-glazed windows - 1,365,000 rubles.
The amount of these costs will be partially included in the cost of the finished product. And it will fully pay for itself over time. Current costs include the cost of materials - 4290 rubles per 1 m2, in terms of 20 finished units per shift, with an average size of 1.68 m2 and the number of shifts per month - 22, you can get a total consumption of materials per month - 3,160,000 rubles.
- The price of one product is 9,500 rubles.
If all the windows produced are successfully sold, you can get 4,180 thousand rubles in profit. Subtract the cost of materials, the cost of maintaining the premises and the wages of workers, resulting in 670 thousand rubles of net profit. The profitability percentage is 19% - a fairly high figure, it indicates a quick payback on invested capital costs, this will happen in a year and nine months, under favorable conditions and constant prices for components.
