Pilger Dies

We specialize in manufacturing high-precision Pilger Dies that are essential for cold pilgering processes used in the seamless tube and pipe industry. Our dies are custom-engineered and meticulously crafted to deliver superior dimensional accuracy, excellent surface finish, and longer die life—making them ideal for reducing the diameter and thickness of tubes with precision.

Manufactured from high-grade alloy tool steel and heat-treated for maximum durability, our Pilger Dies play a critical role in producing seamless tubes for industries such as automotive, aerospace, nuclear, medical, and petrochemical.

What Are Pilger Dies?

Pilger Dies are critical tools used in cold pilgering mills, a metal forming process where seamless metal tubes are passed through a pair of rolling dies. The dies work in a reciprocating motion to gradually reduce the tube's diameter and wall thickness while improving its surface and mechanical properties.

Technical Specification

Manufacturing Features:

• High-Quality Tool Steels: Made from D2, H13, or other premium-grade alloy steels for exceptional strength and wear resistance.
