Every new program starts with your print, requirements, and volume targets. Our engineering and tooling teams collaborate from the beginning to evaluate geometry, identify critical tolerances, and create a design strategy that supports reliable, repeatable production. CAD/CAM modeling, process knowledge, and decades of tooling experience guide each decision and keep tooling aligned with your production goals.

Expertise Across Fine Blanking and Metal Stamping

As a manufacturer with deep roots in fine blanking and custom metal stamping, our tooling capabilities support tight-tolerance work and complex features.

We develop and maintain:

  • Fine blanking tools for presses from 100–700 tons
  • Progressive and compound dies for intricate stamping programs
  • In-die features such as shave stations, re-strike operations, and mechanical assembly
  • Support tooling for CNC machining, grinding, and overmolding operations

Every tool is built for long-term consistency, clean shearing, and stable production across the full run. Toolmakers stay involved through tryout, PPAP, and production so adjustments happen quickly and efficiently.

A Fully Equipped In-House Toolroom

Our toolroom operates as an integrated extension of the manufacturing floor. Equipment and capabilities include:

  • CNC milling and turning for tight-tolerance die components
  • EDM for sharp corners and complex internal profiles
  • Surface and form grinding for precision die surfaces and shut heights
  • Dedicated resources for gauges, fixtures, and special tooling

Direct communication between toolmakers, engineers, and production staff helps keep schedules moving and eliminates the disconnects that often occur when relying on outside suppliers.

Maintenance and Continuous Improvement

Tool performance stays stable through structured maintenance and ongoing evaluation. Our team manages:

  • Scheduled inspections and tracking of wear components
  • In-house sharpening, rebuilding, and replacement of punches, inserts, and die sections
  • Rapid response when tooling requires real-time adjustment or repair
  • Updates that support engineering changes or volume shifts

Long-term tool health reduces downtime, strengthens part repeatability, and supports smoother production flow.

In-house tooling gives OEMs an efficient, predictable launch process. Coordination improves, changes move faster, and production teams stay aligned throughout each stage. With IATF 16949:2016 and ISO 14001:2015 certifications, our tooling operations follow the same disciplined standards that guide every program at Principal.
