Custom Stamping Punch – PG Profile Grinding Precision Manufacturing
Custom Stamping Punches for Precision Stamping Die
As a specialized PG profile grinding outsourcing manufacturer, we provide non-standard stamping punches customized strictly according to customer drawings and technical requirements.
Steps：
- Grinding
- EDM (If required)
- Final PG Profile Grinding
Results：
- Accurate External Profiles
- Clean Cutting Edges
- Well-controlled Radius Transitions
PG profile grinding enables precise machining of complex geometries and small features that are difficult to achieve through conventional processes.
Hepha stamping punches are suitable for micro-sized components, special profiles, and tight-tolerance applications. They are commonly used in progressive dies and high-speed stamping operations.
