Application Case: PEEK Surgical Guide and Medical Fixture Machining

Application context

PEEK medical fixtures and surgical guides require careful language: prototype, non-implant, implantable-grade or validated production each means different documentation and risk.

This is an application case playbook, not a fabricated customer success story. It describes the engineering information a buyer should prepare and the manufacturing route FabVector would evaluate before issuing a firm quote.

Suggested manufacturing route

• Machine with sharp tools and low-stress clamping.
• Finish critical slots and holes after roughing to improve stability.
• Deburr edges and document dimensions that interact with instruments or anatomy models.

Material and finish decisions

• PEEK for high-performance polymer medical hardware.
• PEI/Ultem for heat-resistant fixtures where PEEK is not necessary.
• Titanium Grade 5 when metallic strength and biocompatibility are required.

Quality and risk controls

• Do not assume implant suitability without exact grade and regulatory context.
• Clarify sterilization and cleaning exposure.
• Thin flexible features need tolerance review.

What to include in the RFQ

• Material grade, certificate requirement and intended use.
• Critical dimensions, burr/edge criteria and cleaning expectation.
• Prototype, trial, or production-intent status.
