We machine production parts for Medical Devices and Instruments customers, from single prototypes through to repeat batches of tens of thousands. Typical work covers surgical instruments, implant trials and pump housings, usually in 316L or Titanium Grade 5.
What makes Medical Devices and Instruments different from general machining is not the geometry — it is the documentation and the failure modes. The parts that come back are the ones where material traceability is mandatory — a mill cert is not optional was not designed out at the start.
Parts we machine for Medical Devices and Instruments
- Surgical instruments
- Implant trials
- Pump housings
- Sterilisation trays
Materials we run for Medical Devices and Instruments
- 316L
- Titanium Grade 5
- PEEK
- ULTEM
- 17-4 PH
Standards and documentation
- ISO 13485, FDA 21 CFR 820, ISO 7153 for instruments
Tell us which standard applies and which documents you need with the shipment. Dimensional reports, material certificates, certificates of conformity and first article inspection reports are all available, and it is much cheaper to agree them before the batch runs than to reconstruct them afterwards.
Where Medical Devices and Instruments projects usually go wrong
- Material traceability is mandatory — a mill cert is not optional
- Surface finish affects cleanability and bioburden
Tolerance and finish we hold
| Requirement | Typical capability |
|---|---|
| General tolerance | Ra 0.4 um or better on fluid paths; +/-0.01 mm on mating features |
| Surface finish | Ra 0.4 to 3.2 um |
| Material certification | EN 10204 3.1 on request |
| Inspection | Dimensional report, CMM report, FAIR |
| Packaging | VCI and desiccant for steel, individual wrap for cosmetic faces |
Frequently asked questions
Do you have experience with Medical Devices and Instruments parts?
Yes. Typical parts we run are surgical instruments and implant trials. We can share the process route and inspection approach for a comparable part before you commit.
Which materials do you recommend for Medical Devices and Instruments?
316L, Titanium Grade 5, PEEK, ULTEM. The right choice depends on which of corrosion, weight, strength and cost is the binding constraint, and we will say so plainly rather than quoting the most expensive option.
What documentation do you provide?
A dimensional report and a certificate of conformity as standard. Material certificates, CMM reports, FAIR and PPAP submissions are available when your quality system requires them.
What tolerances do you hold for Medical Devices and Instruments parts?
Ra 0.4 um or better on fluid paths; +/-0.01 mm on mating features is typical for the industry. Tighter tolerance on individual features is possible and is quoted against the specific feature rather than the whole part.
