Medical Device Finishing
Many life changing breakthroughs in the medical device manufacturing field are made possible through technological innovations. As orthopedic devices, cardiovascular implants, and surgical instruments evolve, surface finishing techniques must also continue to improve to support the medical device manufacturing industry. These groundbreaking advances are only made possible by using the newest materials along with continuously improved machining techniques and surface refinement processes.
High Quality Finishes
Only the highest quality super alloys are able provide the corrosion and wear resistance needed. The combination of complex geometries with these exotic alloys makes it especially difficult to maintain the smooth, crevice free surfaces these parts require. Through our work with titanium, stainless, silicone and polymer alloys, we have developed and documented processes designed to ensure each finished part meets or exceeds strict medical requirements. Our experience producing high quality surface finishing is a crucial step in the manufacturing process of medical instruments, orthopedic implants, knee and hip replacements, bone screws and plates, catheters, reattachment buttons and other surgical support items used in the operating environment; handles, trays, hooks, clamps, drill bits, and drill guides.
View Before and After results
Mass finishing is an extremely consistent surface finishing technology that matches well for the medical device industry. Dimensional accuracy, component production efficiency, and high performance surface finishes have become a medical engineering requirement. Mass finishing technology has played an essential role in delivering consistent quality surfaces to medical instruments, implants, and pharmaceuticals. ISO Finishing has developed proven finishing processing results that contribute to the life cycle of medical device manufacturing.
Benefits of Medical Device and Equipment Metal Finishing
- Improve Part Durability and Strength
- Improved Corrosion Resistance
- Reduce Manufacturing Cycle Times
- Maximize Product Yield
- Provide Consistent Surface Finishing
- Uniform Cleaning and Sterility
- Compressive Stress Gains
When the application requires higher strength, resistance to repeated heat cycles and corrosion resistance, today’s stainless and titanium alloys deliver. Although more expensive and difficult to machine, these materials provide the durability to meet the high-test requirements of the medical industry.

Centrifugal Barrel Finishing
Barrel tumblers work well for jobs requiring heavy burr removal. Centrifugal barrel finishing machines are also good for burnishing, rapid radiusing of edges, and heavy deburring. Removing excess material or polishing medical parts, remove burrs, improve surface appearance, polish and clean are all possible using centrifugal barrel finishing equipment.
In the manufacturing world, deburring refers various methods used to remove burrs, the residual rough edges or protrusions left behind after a part is produced. Burrs can affect the surface quality of manufactured parts produced where performance, safety, and appearance of a part is concerned.
Deflashing is the process of removing residual aluminum, titanium, or stainless material used in the manufacturing process. The deposition of small bits of residual material called “flashing” may appear each part. The particles can be removed using a centrifugal barrel machine for a fast and cost-effective method of removing any residual particles.
Our passivation of stainless steel system has been designed to offer our customers a one-stop solution tailored to meet the stringent ASTM a967 specification for the cleaning, testing, and passivation of stainless steel, titanium and other metallic parts. Our relationships with local and national medical manufacturers and our expertise allow us to be a true value-added solution in passivation services to our customers finishing needs.
The presence of burrs, parting lines from castings or other surface imperfections affects the adherence, continuity, and general durability of plated materials. Metal surfaces often require polishing and buffing prior to decorative plating. ISO Finishing understands the importance of pre-plate finishing. Polishing is not only used to enhance the appearance of a part, it also helps prevent contamination of instruments, remove oxidation, create a reflective surface, optimizes performance and can prevent corrosion in pipes. When it comes to machined parts, smoother is better for reducing heat and friction.
Radiusing is a type of deburring which entails the removal or rounding of sharp part edges formed during the medical manufacturing process. Parts with sharp edges can be radiused to pre-defined specifications using centrifugal barrels, vibratory bowls and centrifugal disc machines.
Ultrasonic cleaning is an environmentally friendly alternative to the solvent based cleaners previously used. Ultrasonic cleaning uses high frequency sounds waves, those beyond the range of normal human hearing (18 kHz), and an appropriate cleaning solvent to remove contaminants from parts. The ultrasound can be used with just water or be combined with surfactants to gently remove residual cutting oils and microscopic chips.
