Modern pvc wood or aluminium windows doors are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames. Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather.Windows often have a latch or similar mechanism to lock the window shut. To manufacture windows without mistakes, everybody needs machines without mistakes. The first step is the cutting process and maybe it is the most importent process during windows manufacturing, because if you make the first step wrong the welding result will be misarable and the corner and surface cleaning process, too. It is very importent that the sawblade of the cutting machine has no balance problems, here we as Baertec provides our customers sawblades from the german company Schaeffer Herford made in Germany. Our pneumatic or hydro-pneumatic cylinders are our own manufactured systems by Baertec. For more informations regarding our special patended hydro-pneumatic system of Baertec, please contact us.
