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. The machine's base structure is crafted with precision using 10mm steel plate welding and a solid 30mm steel bottom table. CNC machining ensures a flawless surface. With an integrated pre-cutting system, the machine automatically cuts the coil upon order completion, significantly conserving material.
 

Our system boasts 7 units of automatic change functionality, including seamless interchange between C&Z shapes, and easy adjustments for width and height.

Advantages:
1. Effortlessly adjust sizes with our advanced PLC control system. Enjoy simple access and learnability, significantly reducing labor costs. Produce a variety of purlin sizes without the need for manual roller or spacer changes.

2. Pre-strengthening during forming ensures the perfect shape every time.

3. Infinite size cutter allows size changes with just a few spins, enhancing efficiency.

4. Experience easy operation and benefit from low maintenance costs.

5. Integrated pre-cut system saves material, optimizing resources.

6. Seamlessly interchange between C/Z shapes with just one button.
