Product Description

Automatic Interchangeable Steel Frame CZ Purlin Roll Forming Machine

Introducing our Heavy Duty Quality C Z Purlin Machine, featuring a robust 48mm roll station frame. Engineered with precision, it includes a 10mm steel plate welded bottom structure and a 30mm steel plate for the bottom table. Each surface is meticulously processed using CNC machinery. With the added benefit of a pre-cutting system, material is automatically cut upon order completion, significantly reducing waste.
 

Our 7-Unit Automatic Change System includes interchangeable C&Z configurations, adjustable feeder, and customizable width and height.

Advantages:
1. Equipped with PLC Control for size adjustments, the system ensures easy access and is simple to learn, effectively lowering labor costs. It allows the production of various purlin sizes without the need for manual roller or spacer adjustments.

2. Forming with pre-strengthening to guarantee the perfect shape every time.

3. An infinite size cutter that allows quick size changes with just a few spins.

4. Simple operation and low maintenance costs.

5. Pre-cut system designed to minimize material wastage.

6. Effortless C/Z interchangeability with a single button press.
