PREZ-MET PVC and aluminium window production line

PREZ-MET PVC and aluminium window production line is a state-of-the-art and comprehensive solution for the mass production of windows. The system enables complete machining of PVC and aluminium profiles within a single working cycle. The production includes all key stages – from precise profile cutting, through milling, drilling, welding to final cleaning of the elements.

The PREZ MET window production center is made up of three smaller integrated production lines – one line for the production of window frames and two lines for the production of window sashes. They consist of machines from renowned manufacturers from 2005-2016:
– ROTOX ZSA 263 cutting center
