Because of its many technical advantages and versatility, wet blasting is the fastest-growing segment in the field of shot blasting.
As with dry blasting, the available scope of wet blasting machinery ranges from simple, low-cost blast cabinets to sophisticated, partially or fully automated systems. Customers can choose between a wide spectrum of standard wet blasting equipment, however, for certain applications, special custom-engineered systems may offer the most efficient and cost-effective solution.
The machine type is usually determined by the processing task, the size and shape of the work pieces, and the desired degree of automation. Frequently, multi-axis robots are used for work piece handling or guiding the blast gun movement.
Rosler has extensive experience in wet blasting technology and the development of customized solutions. We have even developed the Rosler PureFinish® system for cleaning stainless steel components for the chemical, food, and pharmaceutical industries through wet blasting. This system cleans the work piece surface while facilitating cleaning, sterilization, and prohibiting bacterial growth.

Within the food, chemical, and pharmaceutical industries, hygiene is a top priority. For safety and quality assurance, the occurrence of contamination through bacteria, proteins, or other elements must be prevented. Process plants require a defined, homogeneous, and reproducible surface for all parts that come in contact with food, beverages, chemicals, and pharmaceutical products.
Rosler delivers full compliance cleaning for stainless steel surfaces with PureFinish®, a unique wet blasting process.
What is PureFinish®?
Rosler developed this proprietary blasting process to deep-clean stainless steel components. Media specifically designed by Rosler for this environmentally friendly process remains suspended in water and is propelled onto the work piece surface with velocity.
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.
