Plastic Tumbling Media
Gentle, precise deburring and pre-plate finishing for softer metals like aluminum, brass, and zinc. Protects delicate part geometries while delivering exact Ra values.
Why Choose Plastic Media?
Pre-Plate Quality
Leaves a smooth, matte finish ideal for anodizing or plating. Prepares surfaces beautifully without harsh scratching.
No Impingement
Lighter weight prevents surface peening or damage to threaded parts, protecting your most delicate geometries.
