Craniomaxillofacial implants
As photo etching machines component features simultaneously, complex mesh designs cost no more to produce than simple ones and counter sinks can be included at no additional cost.
Pacemaker battery grids
Precision Micro photo-etches more intricate titanium anode and cathode battery current collector grids, ensuring reliable energy supply from a smaller footprint.
Pacemaker screening cans
Our micro pacemaker screening cans feature an electrical insulator selectively applied to reduce arcing.
Hearing aid contacts
Micro contact springs used in hearing aid PCBs are stress-free and can be etched to ±0.025mm accuracy.
Medical device electronics
We photo-etch a wide range of electronics components, burr- and stress-free, with clean profiles and no heat-affect, making them ideally suited to the requirements of the medical sector.
Bone saw blades
Precision Micro supplies 1,000s of sagittal and oscillating bone saws each month, machined to ±0.005mm – impossible with laser cutting and grinding.
Materials
We offer an ISO 13485 accredited photochemical etching service for medical devices and instrument manufacturers looking for clean, precise, fast and economical component supply from the widest range of medical-grade materials.
Some of the typical medical components we manufacture include:
- Complex, burr and stress-free cranial and dental implants
- Ultra-thin cathode battery current collector grids used in pacemakers
- Sagittal and oscillating bone saw blades with tight tolerance teeth
- Sensor and valve components used in ventilators
- Micro cochlear implant flexures and electronics components
Photo-etching medical grade materials
Metals and alloys for medical applications are characterised by their high strength-to-weight ratio, biocompatibility and corrosion resistance, all attributes which make them difficult to machine using traditional metalworking technologies, and indeed photo etching.
As one of the world’s only suppliers of titanium etched medical components, we have the know-how to supply a quality-assured, highly repeatable medical etching service from specialist metal grades, including:
- F67 titanium for medical implants
- 316-grade stainless steel for cleaner medical devices
- Ultra-hard Sandvik strip steels for medical cutting tools
Clean, accurate and quality assured
Photo etching is a clean process with no recast layers, metal swarf or chips.
Using tightly controlled ambient temperature chemistry to selectively remove metal, atom-by-atom, parts can be etched and supplied with, or without, post-cleaning and packaging in clean-room conditions.
As one of the only chemical etching companies supplied to ISO 13485, medical device manufacturers can rely on the quality and stability of our processes.
Prototype to volume – fast
Photo etching uses the same low-cost digital tooling for prototyping and production parts, meaning clinical trials can be conducted economically and products to get to market faster.
Custom, in-house solutions
We can combine photo etching with other inhouse processes, such as wire electro-discharge machining, to cut medical instruments to tighter tolerances.
Micro-crevices can also be removed by inhouse electropolishing to give medical devices up to thirty times more corrosion resistance.
