Precision Progressive Stamping Die Manufacturing China
High-speed terminal stamping tooling, motor core lamination dies, deep-drawing tooling, and multi-station progressive dies. Engineered with sub-micron tungsten carbide punches, automated in-die tapping, and speeds up to 1200 SPM.
Progressive Die vs. Transfer Die Selection Matrix
Choosing between progressive and transfer die architecture depends on annual part production volume, raw material strip width, and part geometry complexity.
| Stamping Architecture | Strip Carrier & Feeding Mechanism | Production Speed (SPM) | Best Fit Application & Part Geometry |
|---|---|---|---|
| Progressive Stamping Die | Continuous coil carrier strip carries part through 10–40 stations | 300 to 1,200 SPM (High throughput) | Electronic connector terminals, automotive fuse blades, small brackets, high-volume contacts (>500K units/yr) |
| Transfer Stamping Die | Mechanical fingers transfer discrete blanks between independent die stations | 20 to 80 SPM (Medium throughput) | Deep-drawn cylindrical cans, large automotive chassis panels, parts requiring 360° deep flanging |
| Compound / Single Stage | Single station performs blanking and piercing simultaneously | 30 to 120 SPM (Batch production) | Flat washers, simple shims, low-to-medium volume flat stamped components |
🔗 Cross-Tooling Joint DFM: If your stamping terminals are destined for plastic housing assembly, independent tooling development risks burr interference and pin tilt. Read our technical whitepaper on how cross-tooling DFM prevents terminal-housing mismatch.
Strip Layout CAE & Springback Compensation
We perform full 3D strip layout design with AutoForm forming simulation, calculating non-linear material springback to guarantee dimensional accuracy on high-strength copper and stainless alloys.
Finite Element Forming CAE
Simulates thinning, wrinkling, and strain hardening across bending stations—see our guide on how to compensate for springback in progressive die design before cutting steel.
Reverse Springback Camber
Tool steel punch angles are pre-compensated by 1.5°–3.5° to achieve exact 90.0° ±0.2° post-forming bend angles.
Sub-Micron Wire-EDM
Seibu & Sodick slow-wire EDM cutting Ø0.05mm wire with ±0.0015mm punch-to-die clearance for burr-free edges.
Modular Quick-Swap Inserts
Carbide punch and die blocks are 100% interchangeable, enabling rapid on-press replacement in under 10 minutes.

High-Speed Stamping Economics & 50M+ Stroke Tooling ROI
High-speed progressive stamping dies dramatically reduce the amortized tooling cost per part while eliminating manual secondary assembly.
📈 Stamping Cost Amortization Formula
Cost Per Part = (Strip Material Cost) + (Press Hour Rate / (SPM × 60 × OEE)) + (Tooling Cost / Total Tool Life Strokes)
