Porcelain Tumbling Media

Porcelain is fine white clay consisting of various ceramic elements, with kaolin being the most common one. Its chemical composition makes porcelain tumbling media relatively non-abrasive. As a result, it has a low wear rate, making it an excellent choice for polishing and burnishing metal and plastic parts.

Like any other tumbling media, it also comes in different shapes and sizes. Inovatec offers porcelain tumbling media in triangular, tri-star, spherical (micro bite) and cylindrical (pin) shapes.

This tumbling media can generate the mirror surface finish required in many industrial and aesthetic applications. To work with metal workpieces, however, you have to use one of our compounds with a suitable porcelain tumbling media.

Porcelain polishing media can be used for ceramic coated exhaust pipe polishing and metal ball burnishing.

Data Sheet

Porcelain media needs to reach the entire surface of the workpieces to create the mirror finish. So, the selection of the media largely depends on the shape and geometry of the parts to be processed. Our expert engineers will run different sample tests to see which one best fits your requirements. Contact us for further details.
