Plastic media consists of polyester resin combined with abrasive particles. It is lightweight and commonly used where dimensional control and gentle finishing are important.


Advantages

  • Very lightweight, minimizing part damage.

  • Excellent for preserving tight tolerances.

  • Produces smooth surface finishes.

  • Ideal for soft metals and delicate components.

  • Generates less noise during operation.

  • Lower risk of edge rounding compared to ceramic media.


Disadvantages

  • Slower cutting action than ceramic media.

  • Higher initial media cost.

  • Not suitable for removing heavy burrs or scale.

  • May require longer processing times.

  • Can generate residue and require more frequent cleaning than synthetic media.

  • Can become less effective in applications requiring aggressive stock removal.


Best Applications

  • Aerospace components

  • Medical devices

  • Aluminum parts

  • Zinc die castings

  • Precision-machined components
