Manufacturing of windows requires precision, and this is the reason why our manufacturing lines are controlled by computers. A perfect window would not be developed, however, without the help of a human. Therefore, at every stage, the possibilities of a state-of-the-art machinery fleet are complemented by knowledge and expertise of our staff that also carries out operational control. They check the correctness of the previous work prior to continuing with the next operation.

Termo Profil uses Brügmann, Gealan, Salamander, Schüco and Winkhaus profiles for windows manufacturing. By storing the entire surface of profiles in a flat position, on a surface which is sufficiently stable, we avoid any possible deformation at the stage of storing the profiles.

How is a PVC window developed in Termo Profil?

Beginning to produce a window, we start with cutting the profile considering the dimensions indicated in the order. We use the SD 500 double head saws and the CAT 500 single head of the cutting centre. We have chosen these devices as, besides their standard functions, they have a function of self-zero balancing, which guarantees the correctness of the required dimension. The process is controlled by a computer - the data with information for saws are entered with the use of the local area network - LAN. Precise cutting of profiles with strict dimensions is provided by a magnetic reading of length, which controls movement of the motor of the driving head. We use MEX 230 band saw for cutting steel reinforcements

When the profiles are already cut to size, steel reinforcements are put inside them by the workers and they are screw together with the use of GEVO pneumatic screwdrivers. Such prepared frame elements are transferred to the machining centre where all technological holes are made, such as: "bean-shaped" weep holes, vent holes and holes for a bar connector. Decompression holes and holes for a window handle in the elements of a window sash are made with the use of manual milling machines by PREZMET and FIMTEC.

One of the most important production stages is welding of frames and sashes with the use of computer-controlled welding machines. We use KMW and Rotox four-head welders for this process. They guarantee supervision over all the parameters such as welding temperature, welding time or pressure for a profile. Positioning of profiles is also done electronically. Upon welding, there is time for cleaning up corners of a welding hump of the frame and sash as well as other spreads with the use of STB and Rotox cleaners.

Fitting, which is furnishing frames and sashes in multi-point locking fittings by Winkhaus, is the next step. Fitting of frames and sashes is carried out separately on two lines. Specialist tables are equipped with a screwing unit with automatic delivery of bolts for fittings on surfaces and corners, a hydropneumatic cutting-off machine for fittings, a measuring system and a drilling unit for corners fitting.

Welds with fittings are joined in a complete window which is transported to a glazing position and a quality control position with the use of special roller platforms.

Tailor made glass inserts, provided by the outside company, are inserted to a sash or a frame. Glazing is performed with the use of hydraulically lifted or lowered worktop, equipped in a roll conveyor, which transports windows on a calibration and a control positions.

Upon glazing, the window sash is adjusted to the frame (wedged) and glazing beads are inserted.

To avoid scratching, the windows are secured with special cork dividers and assembled on special L-shaped stands.
