Joint Reconstruction, Part 6 – Shot Blasting for Surface Finishing, Coating Preparation, and Increased Component Life Span

Leave a comment

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.

Forge & Foundry, Part 7 – Selecting a Shot Blasting Machine for Forgings, Non-Sand Castings, and Powdered Metal Components

Leave a comment

This installment of Rosler Metal Finishing’s Forge and Foundry Series continues with shot blasting machine selection considerations for forgings, non-sand castings, and powdered metal components.

While none of these work pieces contain sand, their surfaces may show oxidization or – in the case of ferrous metals – heavy scale/rust caused by iron oxide.

All forms of oxidization must be removed to ensure that subsequent manufacturing operations such as machining, coating, and painting are economical and efficient. Poorly cleaned work pieces may cause additional processing, premature wear on milling tools and drill bits, excessive pollution within coolant systems, and inefficient adhesion of coatings and paint.

Traces of oxidation may also impact the work piece’s functionality.
