We forgot about many problems when started to use vinyl windows. They do not demand much care and are very convenient. Let’s visit the factory and see how they are produced.
The car of the factory goes to the production site in Fryazino.
Ready products wating to be sent to clients.
We’ll trace the production process from the end and ready products will be the first to see. Here window frames are inserted into glass units.
When experts check the products assembly they are packed and sent to the “pyramid” (the construction on which the windows are fixed being carried in trucks).
Glass unit is inserted with help of a tyre lever.
Special molding fillets are put under the glass unit, they distribute the weight of the glass unit and prevent undesirable tension in the glass, caused, for example, by temperature drop.
Window profiles are to be fixed under the farmes to prevent their damage while transportation.
Workbenches have nap not to scratch the profiles.
They use moulds to make holes for fittings. The fittings are screwed on very fast. A small inaccuracy makes all the window defective. Sealing rubber band is fixed manually with molecular glue.
Parting shear for the fittings
Every workbench has its own set of pneumatic drills and screwdrivers with positive bright color wires.
“I do not accept defective goods”
Not on their places. Guess what’s missing?
The frames casements are connected by welding. The profiles welding is made with help of special equipment.
The temperature of the welded knife is 230 – 250 °С. Heating time – 25-40 sec. Then the knife lifts and the machine joins the profiles. The welding takes the same period of time.
The surfaces to be welded must be clean. The welding seam must be white, if it’s not, the temperature was higher than it had to be or the welding time was exceeded.
The frame will be ready in some seconds
Excess welding is cut off with a cutter.
And here’s what they get
The profiles come from Germany
This saw cuts the necessary length under the angle of 45 degrees. That’s what is needed for rectangular windows.
Then the profiles are reinforced
The factory also uses aluminium profiles for sliding constructions. They are often used for balconies. They do not demand glass units, they are replaced with ordinary glass.
Sandwich panels are often used in the low part of a balcony door.
Art of workers
There are many types of profiles
“Do not delay the loading if you don’t want to be loaded too”
Shop of lamination and bent constructions
To bend a profile it must be heated
Place for smoking
Some workers come by bicycles
German windows – German cars!
“Windows plastics” – life-timewarranty”
