Low density plastic tumbling media is ideal for surface finishing applications that require a balance between effectiveness and part protection. It is especially well-suited for deburring, deflashing, and smoothing operations on softer metals like aluminum, brass, copper, and zinc. These materials are more susceptible to damage during vibratory or tumbling processes, and the lower mass of plastic media helps to prevent impingement or distortion.
This media type is also commonly used on molded plastic parts to remove flash and polish surfaces without scratching. In many finishing lines, it is the go-to media for creating a pre-plate finish—especially when uniformity and surface integrity are critical.
Key Applications:
- Deburring die-cast aluminum components
- Pre-plate preparation for zinc parts
- Surface refinement of brass plumbing fittings
- Smoothing molded plastic housings
