Thread rolling is a cold forming process where rotating hardened steel dies are pressed against the surface of a cylindrical blank causing the thread profile to be created in the raw material. The cold forming process gives the thread a higher fatigue strength than a cut thread. The following link provides a more detailed description of the Thread Rolling Process.
Namco Tooling provides a range of products and services for Axial and Tangential thread rolling. Further details can be found below.
"The introduction of Namco axial rolling heads enabled our company to significantly reduce our spend on thread rolling dies and dramatically increased roll life.
