From rugged enclosures to high-strength structural parts, industrial applications demand components that can take a beating and perform without fail. At Principal Manufacturing Corporation, we supply custom metal stampings, fine blanked parts, CNC-machined components, and overmolded plastic assemblies built to thrive in harsh, high-demand environments.

Our vertically integrated production model allows us to control cost, quality, and lead time, helping industrial OEMs stay competitive and responsive.

Parts We Commonly Produce

We support a broad range of industrial equipment manufacturers, producing parts such as:

  • Brackets, frames, and housings
  • Mounting plates and supports
  • Drive and linkage components
  • Motor and pump hardware
  • Fasteners, bushings, and clips
  • Sealing and insulating inserts
  • Control panel sub-assemblies

Engineered for Strength and Consistency

In industrial markets, failure is not an option. We provide:

  • Custom precision metal stamping services for components under stress
  • Fine blank stamping for clean edges and repeatable dimensions
  • CNC machining for shafts, fittings, and tight-tolerance mating features
  • Plastic injection overmolding to integrate cushioning, insulation, or grip
  • Secondary operations like orbital riveting, tapping, and grinding for turnkey part delivery

Our team works directly with your engineers to resolve design challenges and simplify downstream assembly.

Principal is certified to IATF 16949:2016 and ISO 14001:2015, and we maintain ITAR compliance for regulated programs. We serve as a trusted partner for industrial OEMs that require documentation, inspection, and consistent part performance.
