Mass Finishing Solutions for the Dental Industry

At Mass Finishing Inc. (MFI), we’ve been providing high-quality and efficient dental finishing solutions for over two decades with our High-Energy Centrifugal Barrel Finishing Machines. The Dental Industry is one of our largest clients, we even created a separate division in 1998 to cater specifically to dental labs. Now known as our HZ-12 and HZ-40, these machines can quickly remove support material and rough edges on 3D printed molds and polish multiple dental partials and crowns in a single batch. By using high-energy finishing, customers can improve their production efficiency and reduce time-consuming methods such as using harsh chemicals with an electropolisher or polishing by hand.

MFI also offers great start-up kits to get labs up and running towards higher efficiency quickly.

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.
