Fine blanking delivers where traditional stamping falls short. At Principal Manufacturing Corporation, we use the fine blanking process to produce complex metal components with fully sheared edges, exceptional flatness, and tight positional accuracy—without the need for extensive value-added processes.

The process applies pressure from three directions to hold the material steady during cutting. This method creates clean interior and exterior forms with consistent repeatability across the full production run. Small holes, tight tolerances, and features near part edges are all possible using fine blank stamping.

Our facility houses fine blanking presses ranging from 100 to 700 tons. Every die is built and maintained in-house by experienced toolmakers using EDM, CNC, and grinding equipment. This setup gives us full oversight from tooling through production.

We work with a wide range of materials, including:

  • Aluminum
  • Copper, brass, bronze
  • Carbon Steel
  • Beryllium copper
  • Stainless Steel
  • Exotic and precious metals
  • Nickel and nickel alloys

Consistency matters in high-volume production. Our team supports automotive, industrial, and OEM programs with a process built around speed, quality, and control. Certified to IATF 16949:2016 and ISO 14001:2015, we maintain rigorous quality standards at every step.
