20 bet window production technology

  • 20bet window production technology, window scheme
  • Any production requires the correct algorithm of the process itself, therefore, the manufacture of

PVC windows 20bet can be divided into 10 main stages:

  • calculation of plastic windows (dimensions of profile blanks, bead, glass and the consumption of fasteners);
  • cutting of 20 bet profiles (frame/ sash / impost);
  • milling of drainage holes to remove excess moisture;
  • reinforcement with a metal reinforcing profile;
  • welding of 20bet window profile (production of frame and sash);
  • processing of welding seams (along the plane of the frame or sash) and stripping of welding seams at the end of the sash;
  • processing of the impost end face and its installation in the frame;
  • drilling holes for hardware and installing it;
  • assembly of double-glazed windows based on calculated data (glass cutting, sealing of double-glazed windows);
  • laying of a rubber seal and shtapikovanie.

To begin with, we recommend that you read:

  • GOST 30674-99 Window blocks made of polyvinyl chloride profiles. Technical conditions.
  • and we, in turn, will try to tell you with “simple” examples, methods and tips about the manufacture of plastic windows.

Calculation of plastic windows

  • it is done either manually or with the help of programs for calculating plastic windows. As a rule, programs are issued in the form of a report for collectors – all sizes and quantity of consumables. By purchasing ready-made window lines from us, we give a collection of calculation programs for FREE! Cutting of PVC profile: frame, sash, impost.

Saws for cutting PVC window profiles

  • at this stage, the cutting of PVC profile whips into blanks is carried out. The accuracy of this operation largely depends on the quality of the window structure as a whole, so it is necessary to pay due attention to the location of the profile whips on the desktop of the cutting machine (horizontal and vertical angles). Therefore, when installing cutting saws, we strongly recommend using the construction level.

All saws can be viewed here (from 15,000 rubles):

  • saws for the production of PVC windows.
  • With a workshop capacity of up to 50 products per day, single-head saws are used, from 50 and above – two-head saws.

The dimensions of the workpieces are calculated by the program taking into account the welding margin (2.5-3 mm on each side).

Milling of drainage drainage holes.
Drainage drainage holes in 20 bet windows
Under the influence of atmospheric phenomena (precipitation: water, snow), moisture may form on the fold of the frame of a plastic window; moisture (or water) may form due to the loose fit of the window sash to the frame.

To remove moisture, it is necessary to mill in the frame and 20bet sash of the drainage hole system.

PVC window drainage is a system of drainage channels in the frame fold. Moisture is removed from the fold through drainage holes, which are milled in the lower part of the window frame. The fold of the frame of all PVC profile systems has an optimal slope, which looks like a flat horizontal surface, but the geometry of the profile itself is made taking into account the natural outflow of water. Also, in addition to removing moisture, drainage holes are necessary to ventilate the internal cavities of the profile.

Milling of holes can be carried out using a conventional drill, electrical devices (in small industries) or specialized machines:
