Power of the crimping tools are controlled by a hydraulic system to make the operation stable and reliable.

The right and left punches are driven by the mechanical linkage of a hydraulic cylinder, realizing the synchronized rigidity feeding of both punches and avoiding useless deforming during the crimping, so as to make more steady junction of window corners.

This machine is easy to operate, machining joint seams with small tolerance for doors and windows with better effect.

Screw joints are used to adjust the distance between the front and rear crimping tools, making the tool alignment much easier.
