Product Overview

Weytrust Plastic Resin Polishing Media

1. Product Composition & Polishing PerformancePlastic resin media ranks among the mainstream abrasives for vibratory and centrifugal finishing processes. Manufactured by mixing premium abrasive grains and high-toughness synthetic resin, it features mild cutting capacity. It can effectively clear burrs, sharp edge flash and subtle surface flaws while avoiding over-cutting on fragile workpieces.

2. Broad Applicable Workpiece MaterialsThis media fits the surface finishing of aluminum, zinc alloy, copper, brass as well as thin-walled precision hardware parts, ideal for delicate metal components with high surface finish standards.

3. Wide Equipment CompatibilitySpecially designed for wet mass finishing, it supports matching with multiple standard polishing equipment, including centrifugal barrel polishers, vibratory finishing machines and rotary tumbling machines.

Weytrust Resin Media Knowledge Points

Professional Guide to Resin Media Polishing

Cutting Grade Density Wear Loss Cutting Power Cutting Grade Application Scenarios
Fast Cutting 1.7–1.75 10–15 0.7–1.1 Ideal for removing burrs, oxide layers and excess materials.
Medium Cutting 1.95–2.0 25–30 2–2.8 Used for surface finishing and correction.
Light Cutting 1.8–1.9 18–22 1.1–1.6 Designed for fine polishing to achieve high-gloss surface.

Mesh Differentiation

Mesh count refers to the number of openings per linear inch on the sieve. A higher mesh count means finer abrasive particles with slower cutting performance and superior polishing effect. A lower mesh count means coarser particles, featuring fast material removal but leaving slight surface scratches.

  • Cutting Grades:resin media cutting performance levels.
  • Density:Unit: g/cm³.
  • Wear Loss:Abrasive wear rate & consumption.
  • Cutting Power:Refers to abrasive cutting efficiency.

Frequently Asked Questions - Resin Media

We have sorted out the most frequently asked questions from customers. If you have any other doubts, feel free to contact us anytime.

No. Higher mesh count means finer particles for slower cutting and better polishing. Lower mesh count means coarser particles for faster cutting and higher material removal.

Fast cutting media is for deburring and removing oxide scale. Medium cutting is for surface trimming. Light cutting is for fine polishing to achieve high surface finish.

They work well with vibratory tumblers, rotary tumblers, centrifugal finishers and other mass finishing equipment.

Lower wear loss means better durability, longer service life and lower overall cost.

With diverse contact angles, it can reach gaps and holes of workpieces, reducing blind spots and delivering uniform polishing results.
