Unlike dry blasting in which only solid abrasive media is used, wet blasting processes use a slurry in which the media is embedded in water. This greatly cushions the impact energy on the work pieces, providing gentler, yet effective results for delicate work pieces.
As the utilization of wet blasting increases, Rosler reminds manufacturers to review their traditional, dry shot blasting applications and consider if wet blasting could provide additional efficiencies, reduced costs, and better results.
Understanding the Differences
As in any surface finishing process, the starting condition of the work piece, its material composition, shape, and final finish largely dictate which finishing application is most appropriate. Understanding how the application changes the work piece is a key consideration.
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.
