Why Choose PG Punches?

• Stable geometry for long tool life
• Accurate fitting for multi-step dies
• Inspection and records ensure repeatable production

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.

Why Mold Makers and Stamping Plants Choose Us
