Our services

Three disciplines, one controlled workflow

Every program runs through the same documented process: build, seal, label, verify — with your specifications and quality requirements driving each step.

Manufacturing + Assembly

Single-use and disposable medical devices, electro-surgical instruments, cardiac insulation pads, Class 1 devices, kit assembly and non-medical products — simple to complex builds.

  • Blueprint-to-production ready
  • Class 1 medical devices
  • Kit assembly

Sealing + Packaging

Cleanroom packaging and sealing performed in our ISO Class 7 controlled environment, with pneumatic, heat, impulse and pouch sealing methods matched to your material set.

  • Pneumatic & heat sealing
  • Impulse & pouch sealing
  • ISO Class 7 cleanroom

Labeling

From simple information labels through to Microscan LVS barcode label verification, so every unit leaves with accurate, inspection-ready identification.

  • Basic & informational labels
  • Barcode labeling
  • Microscan LVS verification

Why manual manufacturing

Non-automated by design, not by limitation

Automation rewards volume and punishes change. Our non-automated approach does the opposite: skilled hands, documented steps, and inspection at the point of assembly. That is what lets us take on complex builds, tight tolerances, and evolving specifications with over 100 years of combined industry experience behind the bench.

Simple or complex assembly, prototype through sustained production — all under an ISO 13485:2016 certified quality management system and an FDA registered facility.

Hands-on precision

Experienced technicians build and inspect at the bench, catching variation an automated line would pass straight through.

Production flexibility

No tooling changeovers to justify. Low volumes, prototypes, and short-notice revisions are routine rather than exceptions.

Quality at every step

In-process verification is built into the workflow under our ISO 13485:2016 certified quality management system.

Scales with your program

From first-article builds through sustained production, the same team stays with your product — averaging 25+ years per client.
