A 6-station nut former is one of the most widely adopted configurations within cold heading machine systems for nut production. Its forming process divides material deformation into six controlled stages, allowing the nut body, chamfer, and internal features to be shaped gradually rather than through aggressive single-step forming.
Compared with lower-station machines, this nut former provides greater control over material flow and dimensional stability. Each station performs a specific forming function, helping reduce internal stress and improve overall shape consistency. This structure supports predictable forming behavior across extended production runs.TAICHUANG introduces this cold heading solution for buyers who focus on process stability, tooling clarity, and consistent nut geometry across standard fastener specifications.
