Like mass finishing, shot blasting is an exceptionally versatile surface treatment technology. Its applications range from general cleaning after casting and forging to shot peening and, even, cosmetic blasting for placing a fine, matte finish on the work pieces.
For shot blasting of orthopedic implants Rosler Metal Finishing recommends mainly air and occasionally wet blasting systems. The blast media is accelerated by compressed air and thrown at the work pieces through a blast nozzle, creating an extremely precise blast pattern compared to turbine blasting. Another advantage of air blasting is that it can be used with metallic, mineral as well as organic blast media.
These attributes and many more make this surface finishing method particularly useful in the medical industry.

While choosing the right implant material is of utmost importance, as discussed in our previous Joint Reconstruction Series post, the significance of optimum surface treatment throughout the entire implant manufacturing process cannot be overstated.
This relates not only to the right surface finish
– be it a high-gloss polish for low friction, a textured surface for easy
osseointegration, or as preparation for subsequent coating, rounded edges, etc.
– but also total compliance with the specified tight dimensional tolerances. The
success of a joint implant is determined by the perfect match between the
various implant components. This depends, to a large extent, on the surface
treatment procedure(s).
With extensive experience in the medical industry, Rosler Metal Finishing is an expert in designing systems and solutions for the treatment of joint reconstruction implants utilizing shot blasting and mass finishing technologies.
Our Joint Reconstruction Series continues with an
overview of the stringent finishing standards for endoprosthetic implants.

Joint reconstruction implants allow millions of
individuals to regain mobility and reduce pain. Just as surgical skill is
required to implant these artificial joints, so is skillful construction and
finish of the joint components themselves.
A leader in surface finishing for medical technology, Rosler Metal Finishing has extensive experience in shot blasting and mass finishing a wide range of medical devices from instruments to implants used specifically for joint replacement.
Our Joint Reconstruction Series continues with an
overview of the most common materials used for these endoprosthetic implants.
Material Standards
The most common materials used for joint reconstruction implants are currently titanium and titanium alloys and cobalt-chromium alloys. Both materials are very tough, corrosion-resistant, highly biocompatible, and have proven themselves to be absolutely reliable.

With more than $18 billion in annual worldwide
sales, implants for joint reconstruction make up nearly 40 percent of all
orthopedic product sales. More active lifestyles and increased life expectation
continue to contribute to the rapid growth of this market segment.
Thanks to significant advancements on the material side and enhanced surface finishing technologies, artificial hips and knees can last more than 20 years before they must be replaced. Rosler Metal Finishing’s shot blasting and mass finishing capabilities are examples of processes and equipment that have and continue to evolve to accommodate the demand for increased endoprosthetics which are also known as orthopedic joint reconstruction implants.
These techniques play a key role in intermediate processing steps including cleaning, deburring/edge radiusing, surface smoothing, and surface preparation for coatings after casting, forging, machining, CNC grinding as well as placing the final finish on the implants before they are inserted.
