SIGMA M-Type Purlin Forming Machine

I. Applications of SIGMA M-Type Purlins
SIGMA M-Type purlins are high-strength, lightweight, cold-formed, thin-walled steel sections with an "M"-shaped cross-section. They are widely used in modern steel structures. They primarily support roof and wall panels and transfer loads in roof and wall systems of large structures such as industrial plants, logistics warehouses, stadiums, and airport terminals. Compared to traditional channel steel, SIGMA purlins offer higher structural strength and improved bending resistance with the same steel content, significantly reducing overall building costs.

III. Siemens Control System
This machine utilizes a Siemens PLC + touch screen control system, coupled with an encoder for precise length measurement and positioning, ensuring the accuracy of each purlin's length and hole position. The user-friendly interface, with multilingual support, offers the following advantages:

High degree of automation, supporting mass production

Real-time display of production data and equipment status

Equipped with fault self-diagnosis and alarm functions

Supports remote technical support and program upgrades

One-touch start/stop for simple, safe, and reliable operation

IV. Technical Features and Advantages of the Machine

High-strength Frame: The machine base is welded from H-beam steel and annealed to eliminate internal stress, ensuring long-term operational stability.

Precision Rollers: Made of high-quality alloy steel, CNC machined and hard-chrome plated, they ensure a smooth, scratch-free surface.

Quick Changeover: Automatically adjusts the width and height of purlins of different specifications, eliminating the need for roller replacement and significantly reducing downtime.

Punching System: Servo-driven hydraulic punching produces a variety of hole shapes with high precision and speed.

Energy-saving and High-efficiency: The optimized power transmission system reduces energy consumption while increasing forming speed.

Safety: Equipped with a safety guard and emergency stop system, it meets international safety standards.
