How do I choose a CNC pipe bender for automotive exhaust production?

Automotive exhaust pipes require complex, tight-radius bends with minimal deformation. You must select a multi-stack CNC pipe bending machine capable of both draw bending and push bending (rolling) for variable radii (1D, 2D, or 3D). To prevent wall thinning and wrinkling on thin-walled stainless steel, the machine must support precise mandrel and wiper die automation. Wonsten Group customizes its CNC benders with multi-axis control specifically optimized for exhaust systems, ensuring zero-wrinkle performance and seamless integration with robotic loading arms.
