Porcelain Tumbling Media
Porcelain tumbling media produces a polished surface on metal and plastic surfaces.
Meanwhile, it has a very attrition rate.
Unlike stainless steel tumbling media, porcelain media does not make work hardening on metal parts.
The main composition of porcelain tumbling media is aluminum oxide.
At Inovatec, we have two main types of ceramic porcelain polishing media: the standard porcelain tumbling media with alumina content 30-40%, and the fine porcelain tumbling media with alumina content 70%.
Porcelain tumbling media is sturdy and robust media.
Inovatec offers four primary shapes in porcelain media.
We suggest the right sizes and shapes according to the geometry of your part.
The most commonly used porcelain tumbling media is porcelain ball, cylinder shape (pins), and triangle and tri-star shape media.
Porcelain ball shape media also called microbrite sphere media. It is also used for ball burnishing process.
The application of porcelain polishing media is comprehensive.
For example, it polishes brass bullet parts, cutlery, and knives, surgical instruments, clock parts, kitchen accessories, fittings, turbine blades, crankshafts, bearings, valves, stationery (ball-pen tops, clips, springs, etc.).
At Inovatec, porcelain tumbling media used in the final stage of processing.
