The lock former machine is a multi-function machine, mainly used in the occlusal process of the flat connection and the closed connection of the circular duct. It can be used in the process of different shapes of the air duct.


Five bite methods of lock former machine:

1. Single flat bite, used for joints of plates and longitudinal joints of ducts;

2. A single vertical occlusion, used for elbows, bends back and forth and the horizontal seams of winding pipes;

3. Single-angle occlusion, used for the longitudinal joints of rectangular ducts or parts, and the corners of rectangular elbows and three links;
