lt adopts high precision passive aluminum on line forming machine with welding effect testing system,guarantee the high roundness and precise dimensions.

The outer plastic-glue and inner plastic-glue adapts two step co-extrusion technology, improves the plastic-aluminum adhesion quality,and make it much easier to adjust and start the production, as well as different sizes shift.

On line air pressure testing device tests if the welding strengthen quallfied.

It adopts PLC control system and HMI for whole extrusion line, synchronization function realized. It helps the group machine production management and quality control.
