High Precision and Consistent Quality

Ensures accurate tube dimensions, precise corners, and uniform welds for MS, GI, and high-strength steel pipes.

Advantage over competitors: Produces high-quality tubes suitable for construction, machinery, furniture, and industrial applications.

Energy and Cost Efficiency

Optimized forming and welding processes reduce energy consumption, material loss, and operational costs.

Advantage over competitors: Lower total cost of ownership while maintaining production capacity.

Flexible and Multi-Specification Production

Supports small-batch, multi-size orders with rapid mold adjustment.

Advantage over competitors:Offers higher adaptability for diverse customer requirements, reducing downtime and improving market responsiveness.

The Square Tube Straight Forming Unit features advanced straight-forming technology, enabling flexible multi-specification production and rapid changeovers. It is ideal for customers with diverse production needs, including small-batch and multi-size orders. Equipped with a highly automated and intelligent mold-changing system, the unit not only improves production efficiency but also significantly reduces both investment and operational costs.

Product Advantages

Material Savings

The straight forming process reduces material costs by approximately 5% compared to traditional methods.

High-Precision Corner Control

Precise adjustment of the four-corner arc radius ensures a visually appealing finish and high strength.

Quick Size Changeover

Enables multi-size, small-batch production without the need to replace rollers.

Intelligent Mold Change

Electric adjustment + fully automated computer control allows one-touch mold change, significantly reducing setup time.

Cost-Effective Investment

A single set of rollers covers all specifications, eliminating the need for additional rollers and storage space.

Enhanced Structural Strength

Optimized forming and welding processes ensure stable dimensions, improved corner integrity, and higher overall tube strength, making it ideal for demanding structural applications.
