Full Auto CZ Interchangeable Machine/ Cz Purlin Roll Forming Machine / Purlin Roll Forming Machine/Quck Change Cz Purlin Machine/Cz Purline Interchangeable Machine is able to produce various sizes of purlin sections such as C purlin, Z purlin, U purlin sections etc…


LEAD TIME:2~3Months

WAY OF PACKAGING:Nude place in container, machine body tightened with steel wire rope and base frame position fixed by heavy steel angle plate. Roller groups cover with waterproof cloth. Computer control system packed with plywood box. Tooling box and regular wearing parts packed with plywood box as well.

ADVANTAGE FEATURES:1.De-coiler storage steel coils and smoothly feeding into forming machine labor save operation. 2. Forming, Punching & cutting at any required length with pre-set quantity automatically. 3.The encoder will record signal feedback and showing exact length of product on display. 4.The total length of finished coil is able to calculate via control panel. 5.Steel rollers are fabricated by CNC precision machine and hard chrome coated. 6.Cutting blade material is Cr12/Cr12Mov (D2/D3) fabricated by CNC machine, heat treatment. 7. Hydraulic system will equip cooling system to keep low temperature during long time continuously in one day.


Full Auto CZ Interchangeable Machine/ Cz Purlin Roll Forming Machine / Purlin Roll Forming Machine/Quck Change Cz Purlin Machine/Cz Purline Interchangeable Machine:

The size variation is via PLC control and auto changing. Even C section change to Z section also automatically. This machine is widely used in PEB construction field. Its size range can be made as per desired requirements and can be fabricated from various material thicknesses and in almost any length. With highly punching accuracy, accurate dimension forming automatically and cut to length, the forming line capable well improved customer production capacity. 

Working Procedure:

Uncoiling– Leveling– Servo Feeding and Punching– Pre-notching– Roll Forming Machine–Post cutting– Collecting
