Stretch Bending

Stretch bending is an industrial equipment specifically designed for the cold bending of metal profiles. It applies axial tensile force to materials such as steel pipes, square tubes, H-beams, I-beams, channel steel, angle iron, and aluminum profiles through a fully hydraulic control system, causing the material to bend in the plastic deformation zone, thereby achieving the desired curvature and shape.

Key features include:
Diverse structures: Common types include rotary table type, double-arm type, and specialized models for specific industries (such as shower rooms, train roof beams, elevators, etc.).

High-precision control: The hydraulic system can precisely adjust the tension and bending angle, achieving a material utilization rate of over 95%, and a maximum bending arc length of up to 12 meters.

Wide applications: Used in large-scale projects such as high-speed rail, subways, automobiles, airports, and stadiums, as well as in various metal processing production lines, for achieving precise bending and forming.
