Porcelain Tumbling Media
Porcelain tumbling media produces a polished surface on metal and plastic surfaces.
Meanwhile, it has a very low attrition rate.
Unlike stainless steel tumbling media, porcelain media does not make hardening on your 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 of 30-40% and the fine porcelain tumbling media with alumina content of 70%.
Porcelain tumbling media is sturdy and robust media.
It can be used either in an industrial vibratory tumbler bowl or high energy centrifugal disc finishing machine.
Inovatec offers four primary shapes of porcelain media.
We suggest the right sizes and shapes according to the geometry of your parts.
The most commonly used porcelain tumbling media is porcelain ball, cylinder shape (pins), triangle, and tri-star shape media.
Porcelain ball shape media also called microbrite sphere media. It is used for the ball burnishing process.
The application of porcelain polishing media is comprehensive.
For example, it polishes brass bullet parts, cutlery, knives, surgical instruments, clock parts, kitchen accessories, fittings, turbine blades, crankshafts, bearings, valves, and stationery (ball-pen tops, clips, springs, etc.).
Porcelain media is widely used for wet tumbling brass parts.
At Inovatec, porcelain tumbling media is used in the final stage of processing.

10. What is the media-to-parts ratio for porcelain tumbling media?
It really depends on the size of your industrial tumbler and the parts you are polishing.
If you are using large vibratory tumblers, then you can add more media for tumbling.
Porcelain tumbling media comes in different densities that suit a wide array of operations.
A good rule of thumb is to multiply the media density by the capacity of your industrial tumbler in a cubic-foot unit.
11. My porcelain tumbling media has sharp edges. What do I do?
Sharp edges in porcelain tumbling media indicate that the media needs to be broken in.
You can tumble your porcelain tumbling media in a vibratory tumbler separately for 4-6 hours and the sharp edges will be rounded.
12. How long does porcelain tumbling media last?
Porcelain tumbling is meant for soft operations like polishing and shining.
So, it lasts a lot longer than traditional deburring media.
However, small porcelain tumbling media will wear down quicker than large media.
