Press & Punch in the Door Frame Production Line

The press and punch play an important role in a hollow metal frame production line.

Normally a hollow metal door frame consists of 3 parts, the header the hinge jamb, and the strike jamb.

In this door frame production process, the three parts are not cut-off thoroughly, hinge holes, strike holes and the joints are punched in sequence.

After roll forming, 3 parts of the steel door frame are still connected, users just need to bend them at the joint and assemble them into a door frame.
