The 7-station long stroke nut former builds on the advantages of a multi-station forming layout while introducing extended punch travel. This combination allows deeper material deformation without compromising forming stability, making it suitable for thicker or taller nut designs.
Within cold heading machine applications, long stroke configurations are evaluated for their ability to maintain material flow continuity during deeper forming operations. By spreading deformation across seven stations and allowing additional stroke length, this nut former helps reduce forming stress and improve dimensional consistency.
TAICHUANG presents this solution for customers producing nuts that exceed standard height or internal profile requirements.

7-Station Long Stroke Nut Formers are typically selected when standard stroke machines reach their forming limits. The extended stroke supports gradual deformation, helping maintain consistent geometry across deeper profiles.
TAICHUANG assists buyers in evaluating whether a long stroke nut former aligns with their product design and production requirements, including material behavior and forming depth expectations.
Q1: What makes a nut former “long stroke”?
It allows greater punch travel, enabling deeper and more controlled deformation.
Q2: Is a long stroke nut former suitable for standard nuts?
It can be used, but it is mainly selected for nuts requiring deeper forming.
Q3: Does long stroke affect forming speed?
Cycle timing depends on configuration; buyers typically prioritize forming stability over speed in these applications.
