All medical technology requires precise surface finishing to ensure safety, strength, and longevity. The specific surfacing goal and technique vary though.
From stainless steel dental drill heads that require deburring and
surface smoothing to stainless steel tweezers that require surface cleaning and
texturing after forging/grinding and induction welding, the specific treatments
are the key to surface finishing success.
In our last medical instrument blog, Rosler Metal Finishing discussed the merits of mass finishing and shot blasting for medical instruments.
This blog will address a particularly challenging form of material in need of surface finishing and answer the question: What specific surface finishing challenges are there in the medical field?

It is not surprising that trauma implants, along with other medical devices, are subject to the most stringent quality standards. Any material defect or malfunction can have catastrophic consequences for a patient.
For implants, the two key issues for manufacturers to deal with are selecting the right material and attaining the required surface finish. The finishing requirements can range from simple cleaning or deburring to surface smoothing and high-gloss polishing. Components exposed to a lot of tensile and bending stress even undergo a shot peening process to improve their fatigue life.
Some implants must have a textured or “rough” finish to promote osseointegration, which is the attachment of surrounding bone tissue to the implant. Other trauma implants require a very smooth surface to prevent the bone from attaching itself to the implanted material.
We’ve created another exclusive surface finishing guidebook to cover this complex topic, in which we will discuss the surface finishing needs of trauma implants and the impact finishes have on their functionality and performance. Examples of mass finishing and shot blasting applications will also be presented followed by detailed machine reports of actual applications used in the industry today.

Among the various technologies used for finishing the surface of medical instruments, mass finishing and shot blasting play a key role, not only as intermediate steps but also for placing the final, finishing touch on these components.
Besides the right material selection, surface treatment is an essential component of the overall manufacturing process of medical instruments. Only high-quality surface finishes guarantee the required functionality, high sterility, corrosion resistance, and absolute reliability that most medical components require, while also providing a satin, non-glare appearance.
To cover this complex topic, we’ve created an exclusive surface finishing guidebook, specifically for medical instruments! In this guidebook we will discuss Continue reading Surface Finishing Guidebook for Medical Instruments
