Objective

Develop a repeatable polishing process for resin Mah Jongg tiles to improve surface clarity and achieve a consistent, high-gloss finish.

A manufacturer near Denver, Colorado producing custom decorative game components required a refined finishing approach to remove routing marks. The process needed to deliver a consistent surface suitable for downstream carving and painting.

Process TechnologyDeburring, Polishing
Equipment TypeCentrifugal Barrel Finisher / Harperizer

Solution

Bel Air developed a polishing process using a Mini Hoppa Harperizer to refine the surface of resin Mah Jongg tiles.

After routing, the tiles showed visible surface marks and fine imperfections that needed to be removed before further processing. A controlled finishing process smoothed the surface and enhanced clarity while maintaining the part geometry.

The result is a repeatable, production-ready polishing process that delivers a uniform, high-quality surface suitable for decorative applications.

  • Removes routing marks and surface imperfections
  • Improves surface clarity and gloss
  • Provides a consistent finish across individual tiles
  • Prepares parts for downstream carving and painting
