Once this is done, the Double Glazing reinforcements are slid inside the profiles and screwed into place at regular intervals with a pneumatic screw-driver.To enable the fittings to be attached later, groups of three holes are then drilled in the sashes, which are also routed, as necessary. In this example, the process is highly efficient thanks to the use of a copy-router incorporating a drilling unit.First, the recess for the lock, and then the triple holes for the handle. The triple holes can also be made using a simple upright drill.
The key stage in the production of windows using polymer profiles is a welding process. The profiles that are to be joined together are laid in the welding machine, pushed forward as far as the groove, and clamped in place. The advantage of using a two-head welding machine is the two corners can be processed at the same time.
