Precision quality inspection

Industries We Serve

Trusted by manufacturers across sectors that demand precision, reliability, and full documentation.

Optics & Photonics

Precision is non-negotiable in the optics world. We machine components for optical assemblies, laser systems, and photonics equipment where surface finish and dimensional accuracy are critical. Our team understands the tight tolerances and material requirements that these applications demand.

Optics & Photonics manufacturing

Key Capabilities

  • Lens housings and barrel assemblies
  • Optical mounts and kinematic bases
  • Tolerances to +/- 0.0005"
  • Aluminum, stainless steel, brass, Invar, and copper
  • Fine surface finishes (Ra 16 and better)
  • First-article inspection reports

Automotive

From prototype brackets to production tooling, we support automotive manufacturers and their supply chains with reliable, repeatable machining. Our multi-machine capacity means we can scale from small development batches to sustained production volumes without sacrificing quality.

Automotive manufacturing

Key Capabilities

  • OEM and aftermarket component machining
  • Rapid prototyping and short-run production
  • Tooling, fixtures, and jigs
  • High-volume production runs
  • Steel, aluminum, and alloy materials
  • Consistent part-to-part repeatability

Food & Beverage

Food processing equipment demands materials and finishes that meet strict sanitary standards. We machine stainless steel components with the surface quality and material traceability required for food-contact applications, from conveyor parts to custom processing equipment.

Food & Beverage manufacturing

Key Capabilities

  • Stainless steel 304 and 316 machining
  • Sanitary surface finishes
  • Processing equipment components
  • Conveyor and packaging machine parts
  • Material certifications and traceability
  • Custom one-off and replacement parts

Defense & Military

Defense work requires precision, documentation, and accountability at every step. We manufacture mission-critical components to military specifications with full material traceability, dimensional inspection records, and the process controls needed to meet government and prime contractor requirements.
