CNC Machining for Medical Devices
Hanstar provides medical device machining for precision components used in medical devices and surgical instruments.
We machine titanium, medical-grade stainless steel, and PEEK on German Hermle 5-axis centers.
Critical features can be held to ±0.002 mm and verified by CMM inspection, with inspection records and lot traceability available for your project.

Medical Components We Machine
Hanstar supports medical device prototyping and repeat production on the same certified production line used for our aerospace and automotive programs. We maintain inspection records and lot traceability from the first sample through production.
Surgical Instruments & Tool Components
Instrument handles, forceps and clamp components, retractor parts and instrument bodies in medical stainless and titanium — reuse-critical geometry held repeatably, batch to batch.
Device Enclosures & Housings
Machined housings, bezels and structural frames for imaging, monitoring and surgical equipment — cut from billet or finish-machined from our own cast blanks.
Orthopedic & Trauma Components
Bone screw, plate and instrument components machined in implant-grade titanium and stainless to print — every lot backed by material certificates and batch traceability.
Fluid Handling & Analytical Parts
Pump bodies, manifolds, valve components and flow-path parts for IVD analyzers and laboratory fluidics, machined burr-free with the flow geometry your assay depends on.
Shafts, Pins & Precision Fittings
Instrument shafts, pivot pins, couplings and fittings where fit, finish and repeatability decide how the instrument performs in the surgeon's hand.
Diagnostic & Lab Equipment Parts
Optical housings, mounts, brackets and precision hardware for diagnostic instruments and laboratory automation systems.
Medical Machining Capabilities
Named machines, verified tolerances, documented inspection. This is the equipment behind every medical component we machine — the same fleet our 5-axis CNC machining service runs on.

Tolerance is only half of a medical qualification
±0.002 mm means nothing to a device customer without the record behind it. Every critical feature is verified on a Zeiss CONTURA CMM with 0.001 mm resolution, 100% of shipments pass final inspection, and material lots stay linked to the finished part. That documented tolerance-to-verification loop — ready to hand over, part by part, in your supplier file — is what medical buyers are really purchasing.

Medical Device Machining — Frequently Asked Questions
Straight answers to the questions buyers ask before sending a drawing.
Are you ISO 13485 certified for medical device machining?
Yes. We hold ISO 13485 certification, alongside AS9100D, ISO 9001 and IATF 16949. Certificate details and customer-specific quality documentation are available upon request.
What materials do you machine for medical devices?
We machine titanium, stainless steel, aluminum, engineering plastics and copper alloys, including Ti-6Al-4V, 316LVM, PEEK and PEI (ULTEM). Material certificates are available according to project requirements.
What tolerances can you hold on medical components?
We achieve tolerances down to ±0.002 mm on selected critical features under suitable machining and inspection conditions. Actual tolerances are defined by your drawing and verified using ZEISS CMM inspection equipment.
Do you provide material certificates and lot traceability?
Yes. We maintain material identification and lot traceability throughout production, linking incoming materials to manufacturing and inspection records. Traceability documentation and material certificates are available according to project requirements.
Can you machine implant-grade titanium and PEEK?
Yes. We machine specified titanium grades, including Ti-6Al-4V ELI (Grade 23), as well as PEEK and other engineering polymers. Please share your drawing and material specifications so we can confirm manufacturing and documentation requirements.
What documentation do you provide for medical device parts?
Documentation can include dimensional inspection reports, Certificates of Conformance (CoC) and material certificates. FAI reports and inspection data packages can also be prepared according to your project requirements.
Is there a minimum order quantity for medical device components?
No minimum order quantity. We support projects ranging from single prototypes and low-volume validation batches to repeat production orders.
Do you sign NDAs before I send drawings?
Yes. We can review and sign customer-provided NDAs or use an agreed confidentiality agreement before receiving confidential drawings. Customer technical information is not published without written authorization.
