Production finishing guidance
Built for consistent deburring, edge conditioning and surface preparation.
Pyramid plastic media provides repeatable part-to-media contact for deburring & grinding. Its geometry and abrasive composition help production teams match cutting action, reach and surface finish to the component.
How to select media
Match the media shape, size, cut and process time to the part material, geometry and finish required. For complex parts or specific edge targets, request a media recommendation before ordering.

Plastic media selection guide
How pyramid plastic media supports a repeatable finishing process.
Plastic tumbling media is selected around the part material, geometry, desired edge condition and the finishing equipment in use. This pyramid profile, sized 1/4" × n/a × n/a, is intended for consistent contact where a repeatable finishing action matters.
For dependable production results, review the machine load, media-to-part ratio, compound, water flow and cycle time together. Trial a small production run when the component, finish target or process changes, then document the setup so operators can repeat it.
Machinist's Vault supplies plastic finishing media for vibratory bowls, tubs and batch-finishing systems. Teams can order the listed production tiers online or request a custom quantity when their media program exceeds 1,000 lb.
