Medical device parts,
traceable and autoclavable.

Prototype and pre-production manufacturing for medical device developers worldwide. Implant trial components, surgical instrument machining, autoclavable enclosures, and 510(k) submission samples with full material traceability.

How medical device customers use us

We're a contract manufacturer that supports medical device developers through the R&D, design validation, and regulatory submission phases. We're not a finished-device contract manufacturer for market distribution — that role sits with ISO 13485–certified suppliers. But for the years between "CAD finished" and "we've selected a production CM," our fast-turn machining, material sourcing, and documentation discipline fill a gap that pure production shops don't.

Typical project types: implant trial components (fit testing, surgeon feedback), surgical instrument machining (in PPSU, PEEK, 316L stainless, or Ti Grade 5), autoclavable enclosures and trays, 510(k) submission sample batches, and bridge production while the customer qualifies their final contract manufacturer.

Material sourcing and traceability

For medical work, material traceability is as important as dimensional accuracy. Every lot of stock we receive is checked against the mill cert, tagged with an internal lot number, and tracked through machining to shipping. When your parts arrive, the FAI report and Certificate of Conformance reference the specific mill lot. If you ever need to investigate a field failure, the traceability chain is intact.

For implant-grade stock (PEEK-OPTIMA®, Ti-6Al-4V ELI per ASTM F136), we source direct from certified mills (Invibio, TIMET, ATI, Baoji Titanium) on a per-project basis with a customer purchase order. Certificate chain is preserved from mill → us → customer.

Surgical instruments and handles

Surgical tool handles, retractors, scopes, and forceps are a steady workflow. Materials are typically 316L or 17-4 PH stainless (passivated per ASTM F86) or PPSU (Radel R-5500) for autoclavable grip handles. We machine, bead blast, passivate or polish, laser-mark with part number and lot, and ship double-bagged in cleanroom poly.

For ergonomic handle designs with complex curvature, we run 5-axis machining on our Beijing Jingdiao JD500 cells. Typical tolerances are ±0.05 mm for cosmetic surfaces, ±0.02 mm for mating interfaces. See our CNC machining page for full envelope and capability.

Implant trial components

"Implant trial" usually means non-implantable components used during surgery to verify size, fit, or feel before the actual implant is placed. We produce trial hip stems, trial spinal cages, trial bone plates, and trial screw sets in Ti Grade 5 or PEEK (non-implant-grade for trials, implant-grade if testing regulatory chain). Each trial set is engraved with size code and lot number.

For actual permanent implants intended for market distribution, customers need an ISO 13485-certified contract manufacturer — we're not that supplier. But for R&D implant prototypes used in cadaveric testing, surgeon feedback sessions, and submission samples, our process and traceability are appropriate.

Autoclavable housings and trays

Device enclosures that need to survive repeated autoclave sterilization (134 °C steam) must be made from PEEK, PPSU, Ultem, or 316L stainless. Polycarbonate enclosures, common on lab-only devices, craze and embrittle after 50 or so autoclave cycles. PPSU is our recommended default for autoclavable housings — see the PEEK materials page for detailed grade selection.

Frequently asked questions

Q01Are you ISO 13485 certified?+
Not currently. We operate under ISO 9001:2015 with documented controls for medical device work: controlled material receipt, full lot traceability, CMM-based First Article Inspection, and controlled shipment documentation. For customers requiring ISO 13485 suppliers, we support your incoming inspection and supplier qualification process and work under your quality system. We do not manufacture implantable devices for market distribution.
Q02Can you source implant-grade PEEK (Invibio PEEK-OPTIMA®)?+
Yes, on a per-project basis with a signed customer PO that names the end application. Invibio requires customer master-file linkage for implant-grade stock; we facilitate the purchase chain and maintain certificate-of-analysis traceability from Invibio lot number through our machining to your delivered parts. Budget 2–4 weeks for stock delivery on top of machining time.
Q03What's the typical scope of a 510(k) sample batch?+
Typically 10–50 pieces produced on matched-production process (same tooling, same fixturing, same inspection) so the samples represent the process your device will manufactured on post-clearance. Each piece carries full dimensional verification; we ship with FAI report, material certs, Certificate of Conformance, and cleaning/packaging per your spec.
Q04Can you clean and package to Class 100,000 cleanroom standards?+
We have a controlled cleaning environment with ultrasonic cleaning, deionized water rinse, and isopropanol final wipe, followed by double-bagging in cleanroom-grade poly. This is adequate for most surgical instrument and non-sterile packaging needs. For Class 100,000 bioburden-controlled packaging, we partner with regional sterile packagers; timelines add 1–2 weeks.
Q05What's the difference between prototype machining and pre-production runs?+
Prototype machining is optimized for speed — we may use wire EDM, manual setup, or reduced fixturing to turn parts in days. Pre-production runs use matched-production fixturing, CNC-controlled inspection, and documented process parameters. Pricing differs accordingly. We're transparent about which mode your project runs in and why.
Q06Do you support design iteration cycles?+
Yes — that's most of what we do. Medical device development typically cycles 5–15 iterations before regulatory submission. We hold customer CAD in our system, honor NDA-protected revisions, and turn each iteration in 5–10 days. For customers running parallel mechanical and biological testing tracks, we can produce sample batches on different revisions simultaneously.
