Enhance Your Mass Finishing Process with the Right Media Selection

Media is an essential component in the finishing process and is required for the proper operation of any Mass Finishing equipment. Finishing media is carefully selected based on its composition, shape, size, and performance to optimize the efficiency and effectiveness of the finishing process.

In addition to the wide variety of media and liquid and powder compounds in our Media Store, we also manufacture our own corn cob blends at our manufacturing facility in Howard Lake, MN.
