Purlin Roll Forming Machine

Purlin Roll Forming Machine

General Overview
The Fully Automatic High Speed CUZ Purlin Roll Forming Machine with Stacker manufactured by Beenew Machinery is ingeniously engineered. It is specifically tailored for the rapid production of C, U, and Z-shaped products through fly-cutting at high speeds, and it operates in a fully automated manner, integrated with an automatic stacking mechanism.

Distinct from the hydraulic punching machine and the automatic purlin stacking machine, the primary roll forming machine employs a non-stop fly-cutting technique. This enables it to maintain continuous production at full capacity, ensuring seamless operation. In practical terms, it can achieve an impressive actual production speed of up to 40 meters per minute.
