Medical Instruments, Part 1 – Surface Finishing Requirements for Medical Instruments

Rosler Metal Finishing understands that medical instruments are subject to stringent quality standards. Whether during an office visit or a complicated surgery, material defects or malfunctions may create dangerous and even fatal consequences for patients and healthcare workers alike. Providing precise and durable surface finishes  for work pieces used in the medical industry is one of our passions.

In a series of blog posts, we’ll discuss the various technologies used for finishing the surface of medical instruments and how mass finishing and shot blasting play a key role, not only as intermediate steps but also for placing the final, finishing touch on these work pieces.

We begin with a basic question: What are the surface finishing requirements associated with medical instruments?

Materials Matter

Medical instruments are exposed to frequent use and subject to highly corrosive atmospheres caused by frequent sterilization in a steam pressure chamber, exposure to chlorine wipes, and ultrasonic cleaning. They must never fail. To minimize wear and prevent corrosion most medical instruments, especially surgical tools, are made from tough, slow wearing, corrosion-resistant, high-performance metal alloys including austenitic stainless steel, titanium, or cobalt chrome.

Surface Finishing Guidebook for Medical Instruments

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.Call to action text in case your image doesn't load.

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
