VAPORMATT

Prosthetic Implant Surface Conditioning

 

Hip knee prosthetic implantSurface finishing of medical devices
for the orthopaedic Industry

Wet blasting is well known within the orthopaedic manufacturing world as the accepted procedure for surface finishing of prosthetic components, due to a number of advantages over other finishing techniques.

The surface finishing requirement varies with different types of orthopaedic implants, but generally falls into two categories; a smooth satin finish, achieved with spherical media, for removing machining marks, burrs and other surface contamination without altering the surface definition for “cementless” devices; and a rough texturing of the surface, achieved with angular media, to create an ideal bonding surface for “cemented” devices.

The Vapormatt Process can be used with different types of media (abrasive) to create either of the desired outcomes.

Being a wet process, no static build-up occurs on the surface of the part, which would otherwise hold microscopic particles. The process is carried out by flow, not impact, so washing and blasting are simultaneously carried out, but a greater advantage is the complete absence of media impregnation, leaving only a nascent clean surface with less need for subsequent cleaning processes or expensive contamination testing. The liquid continuously lubricates the cutting edges of the media ensuring a consistently sharp cutting action and lower media breakdown rates when using very course cuttings abrasives.

Due to Vapormatt’s patented slurry pumping system a range of “micro” medias can also be exploited, this is particularly advantageous when dealing with more specialist materials such as composites and prior to preparation for vacuum surface coating (PVD).

Explosion risks associated with dry processing of titanium components are eliminated. This opens up the possibilities in new applications of utilizing titanium powder as the cutting medium - so avoiding any possibility of secondary contamination.
