Medical device accessories — stainless MIM components

Product Overview

This product family covers small medical-grade metal parts produced via metal injection molding (MIM) for OEM medical buyers. These include surgical instrument accessories, device housing components, orthopedic attachment parts, and other precision stainless parts that benefit from MIM's shape freedom and repeatability.

For medical OEMs, the key advantage of MIM is the ability to produce complex net-shape parts without secondary machining — reducing cost per part, inspection loops, and supply chain complexity.

Typical Applications

  • Surgical instrument handles and gripping components
  • Orthopedic implant adjuncts and attachment hardware
  • Medical device housing and chassis inserts
  • Custom OEM components for diagnostic and therapeutic equipment
  • Biopsy and grasping tool parts requiring clean edge finish

Why MIM Works for Medical Parts

Medical devices demand tight tolerances, clean surfaces, and material integrity — exactly the conditions where MIM delivers. Unlike CNC machining, MIM creates complex internal geometries in a single process step, and unlike conventional powder metallurgy, it produces the near-full density required for stainless medical alloys.

SINTS runs MIM for medical parts on the same XPS5 sintering lines we use for automotive and industrial programs, giving medical buyers access to production discipline that exceeds typical consumer-grade MIM.

Materials, Finish & Build Range

Typical Materials SUS304, SS316L, 17-4PH, and related medical-grade stainless alloys.
Tolerance Reference ±0.05 mm on critical features. Tighter control available for mating surfaces.
Surface Finish As-sintered, magnetic polish, or passivation per medical device requirements.
Process Route MIM primary. CNC finishing available for threaded or datumed features.
Quality Standard IATF 16949 / ISO 9001 production control. ISO 13485-aligned documentation.
MOQ Reference From 3,000 to 10,000+ pcs depending on geometry and material.

Project Support

For medical RFQs, SINTS can review drawings against MIM process capability, flag potential surface or geometry adjustments, and provide first-article samples. If the component will be sterilized, plated, or assembled under cleanroom conditions, noting these requirements early helps align the process route from the start.
