High-Precision Copper Wiper Die for Wrinkle-Free Tube Bending

Precision Tooling for Perfect Tube Bending

In modern tube fabrication, surface quality and dimensional accuracy are critical.
BLMA’s copper wiper die is specially developed to eliminate wrinkles during bending, ensuring smooth deformation and consistent forming results even under tight radii and thin-wall conditions.

Why Choose Copper Wiper Dies

Compared with conventional steel or nylon materials, copper provides:

• Excellent anti-wrinkle performance

• Superior surface protection for stainless steel, aluminum, and coated tubes

• Stable friction characteristics for precise bending control

• Long service life under continuous production

These advantages make copper wiper dies ideal for high-end CNC tube bending applications.
