With worldwide sales at nearly $10 billion annually, there is a high demand for spinal implants. These implants are subject to very specific and strict surface finishing requirements to ensure longevity and fixation to bone.

Mass finishing and shot blasting play key roles in creating the right finish for spinal implants, not only for intermediate surface treatment after forging, casting, machining, additive manufacturing, etc., but also for placing the final surface finish before implantation.

Let’s examine the capabilities of mass finishing and shot blasting for spinal implants and how Rosler Metal Finishing can develop a precise and repeatable finishing process to meet your unique challenges and goals.

Spinal Implants, Part 2 – Processed to Perfection

Along with the material choice discussed in Part 1 of our Spinal Implants series, surface treatment is the most important factor affecting the functionality, performance, and longevity of spinal implants and instruments.

During the manufacturing process they may have to undergo multiple finishing operations including burr removal from previous manufacturing operations, rounding of sharp edges, general surface cleaning, surface smoothing, and, frequently, high gloss polishing.

Treatment steps can also include surface texturing/profiling and shot peening, areas Rosler Metal Finishing has extensive experience in.

This blog post will focus on the finishing requirements and challenges of spinal implants as well as the solutions provided by mass finishing and shot blasting processes and the associated costs.
