Who We Work With
We mainly serve:
- Mold & die manufacturers
- Stamping and punching factories
- Tooling suppliers requiring custom precision parts
Our customers choose us when accuracy and delivery reliability matter more than low price.
Typical Challenges We Help Solve
Do you often face these issues?
- Custom punches with multiple steps or complex profiles are difficult to control in accuracy
- Inserts require tight fitting, causing repeated assembly and adjustment
- Trial mold or modification parts are urgent, but suppliers miss deadlines
- Repeat orders show dimensional inconsistency
Our job is to make these problems predictable and controllable.
Custom Parts We Manufacture
We specialize in non-standard, drawing-based precision components, including:
- Custom punches (stepped, profiled, angled, special shapes)
- Precision inserts and core components
- PG-ground forming punches
- Wire EDM precision profile parts
- Small-size, high-hardness tooling components
- Trial, modification, and small-batch production parts
Each part is manufactured with clear control of critical dimensions and fitting requirements.
