Although more well known for deburring and finishing applications on metal parts, mass finishing techniques can also be used to enhance surfaces and produce edge contour on a variety of different plastic components. Some examples are shown below:


Two-step centrifugal finishing (1) abrasive smoothing (2) final dry polishing.  As centrifugal typically has four barrel compartments these processes could be run concurrently.
These composite fabric parts were smoothed using centrifugal processing that made use of abrasive resin performs and the final smoothed with dry polishing media


Two-step finishing and polishing method with centrifugal isofinishing


These parts were finished in a two-step centrifugal method.  Smoothing was done with fine abrasive resin preforms and then final polishing was accomplished with dry granular polishing media.

Deburring (deflashing) and smoothing of thermoplastic materials can also be accomplished with high-energy centrifugal isotropic finishing systems

Isotropic Finishing and polishing can be performed in centrifugal barrel finishing equipment such as this 4-barrel Model HZ-60 machine.
