Precision Micro specialises in photo etching medical alloys – including 300 series stainless steels, Sandvik strip steels and cobalt-chromium based alloys – and operate Europe’s only dedicated, ISO 13485 accredited production titanium etching capability. This opens up an array of possibilities for medical devices and instrument which require a combination of lightweight, strength, corrosion resistance and biocompatibility.
Biocompatible cranial and dental implants can be extremely feature dense, and demand burr-free edges which traditional machining technologies find difficult to achieve.
Photo etched implants benefit from zero thermal distortion and burr-free openings. Complex, accurate aperture arrays and countersinks can be included at no additional cost, removing the need for additional machining.
Orthopaedic saw blades
Typically, sharp-toothed blades are profiled using laser cutting before grinding to achieve the required tooth offset. By utilising the depth etching technique, one of the world leading medical OEMs partnered with Precision Micro to develop a unique tooth profile which removed the need for the secondary grinding operation.
Today, Precision Micro supplies 1,000s of sagittal and oscillating bone saws each month, machined to ±0.005mm – impossible with laser cutting and grinding.
Ultra-fine, stress-free titanium membranes and micro contact springs used in hearing aid microphones and PCBs can be etched burr-free to ±0.025mm accuracy.
Cardiac rhythm management
Precision Micro manufactures intricate titanium anode and cathode battery current collector grids used in lithium batteries contained within implantable defibrillators, ensuring reliable energy supply from a smaller footprint. We also manufacture micro pacemaker screening cans which feature an electrical insulator selectively applied to reduce arcing.
A wide range of 2-D and 3-D electronics components, including lead frames, EMI/RFI shielding, connectors, contacts, biosensor springs and meshes, can be photo etched burr- and stress-free, with clean profiles and no heat-affect, making them ideally suited to the requirements of the medical sector.
