High Precision Fixed Size C Purlin Roll Forming Machine with Mold Cutting

High Precision Fixed Size C Purlin Roll Forming Machine with Mold Cutting

Product Attributes :

The XINNUO Fixed Size C Purlin Roll Forming Machine is engineered for high-efficiency production of a specific C-channel profile. Unlike adjustable models, this machine features a specialized mold cutting system that ensures a burr-free, clean cut with superior dimensional accuracy. Designed for 0.9-1.2mm thickness materials, it offers a stable production speed of 8-15m/min, providing a cost-effective solution for dedicated manufacturing lines in light steel construction and industrial racking.

Product Description

This XINNUO C purlin machine is a specialized roll forming solution for manufacturers who require high-volume production of a single, fixed-size C-channel. By eliminating the complexity of size-adjustment mechanisms, this machine offers enhanced rigidity and stability. Its standout feature is the precision mold shearing system, which provides a higher quality finish compared to standard post-cutting knives.
