Customer Profile
This peek machining medical prototype case study shows Industry: Medical device prototyping (individual maker) | Location: Austin, Texas, USA | Order: 6 PEEK parts, 3 iterations, 1-month engagement
The Challenge
An independent medical device innovator needed small PEEK (polyetheretherketone) components for a surgical instrument prototype. PEEK is notoriously difficult to machine — high melting point, abrasive to tooling, and prone to stress cracking if machined incorrectly. Most shops reject small PEEK orders due to setup cost and material risk. This peek machining medical prototype case study demonstrates how QDJ delivers results when others can’t.
How QDJ Helped
- Material Expertise: Pre-heated PEEK stock to 120°C before machining to reduce internal stress. Used diamond-coated tooling specifically for PEEK.
- Low MOQ: 6 parts accepted — no minimum order. QDJ runs small-batch prototyping as core business, not a favor.
- Design Feedback: Suggested increasing wall thickness on one thin-walled section from 0.8mm to 1.2mm after FEA analysis showed potential cracking risk during autoclave sterilization.
- Certificate of Conformance: Provided material cert, machining parameters, and surface finish report for FDA submission package.
Results
| Metric | Other Shops | QDJ |
|---|---|---|
| MOQ | 50+ units | 1 unit |
| Per-part cost (6pcs) | $800+ | $195 |
| Lead time | 4 weeks | 7 days |
| DFM feedback | None | Wall thickness improvement |
Client Verdict
“QDJ didn’t just say yes when everyone else said no — they actually understood PEEK. The wall thickness suggestion was spot-on. Our prototype passed FDA review with zero manufacturing questions.”
