Why Top Proto for Medical Device Manufacturing?

Medical device manufacturing requires more than machining capability — it requires a supplier with documented quality systems, biocompatible material traceability, and process controls aligned with the regulatory standards that govern medical device production. Here is how Top Proto specifically supports medical device programs:

Materials and Surface Finishes for Medical Device Parts

Materials

Top Proto machines medical-grade materials including Titanium Grade 5 (Ti6Al4V) for surgical instruments and implant trial components, Stainless Steel 316L for corrosion-resistant instrument shafts and fluid contact components, PEEK for implant-grade structural components requiring radiolucency and chemical resistance, Aluminum 6061-T6 for diagnostic equipment housings and structural frames, Ultem (PEI) for sterilizable instrument components, and medical-grade ABS and polycarbonate for equipment housings and covers.

Surface Finishes

Medical device surface treatments at Top Proto include passivation of stainless steel to ASTM A967 standard for corrosion resistance and cleanliness, electropolishing of stainless steel components for reduced surface roughness and improved cleanability, Type II anodizing for aluminum diagnostic equipment components, bead blasting to specified surface texture requirements on surgical instrument surfaces, and cleanroom degreasing and packaging for components requiring particulate-controlled delivery.
