Cold Forging Dies
Ultra-precision punches and dies engineered for performance. Average lot size: 1.4 pieces — because we believe every single tool deserves the same level of craftsmanship.
Precision That Matters
For over 50 years, Nissin Pertechtual has manufactured cold forging punches and dies that meet the most demanding specifications. Our workshop in Saitama, Japan combines traditional craftsmanship with state-of-the-art CNC machining, wire EDM, and 5-axis milling to deliver tooling that performs.
With an average lot size of just 1.4 pieces, we specialize in what large-scale manufacturers cannot — or will not — do: prototype tooling, one-off custom dies, and small-batch production runs with zero compromise on quality.
Every die is manufactured in-house from start to finish. No outsourcing, no handoffs. One team, one facility, complete accountability.
