Product Description

Automatic Interchangeable Steel Frame CZ Purlin Roll Forming Machine

This heavy-duty C Z Purlin Machine boasts a robust 48mm roll station frame, enhanced with a durable 10mm steel plate welding bottom structure and a 30mm steel plate bottom table. The CNC-machined surface ensures precision and quality. With an integrated pre-cutting feature, the machine automatically cuts the coil upon order completion, thus optimizing material usage and minimizing waste.
 

Equipped with a comprehensive 7 Units Automatic Change System, this innovative machine includes interchangeable C&Z purlin configurations, feeder adjustments, and precise width and height modifications.

Advantages:
1. Advanced PLC CONTROL allows for effortless size adjustments, simplifying accessibility and reducing labor costs. Produce various purlin sizes without the need for manual roller or spacer changes, ensuring operational efficiency.

2. Pre-strengthening during the forming process guarantees perfect shape retention and product integrity.

3. The infinite size cutter facilitates quick size transitions with minimal effort, enhancing productivity.

4. User-friendly operation combined with low maintenance costs makes this machine a practical choice for any production line.

5. The integrated pre-cut system significantly reduces material waste, promoting cost-efficiency.

6. Seamlessly switch between C and Z purlins with the simple press of a button.
