Cryogenic deflashing media are cylindrical sandblasting particle made from polycarbonate monofilaments, available in various colors.
This product is primarily used in liquid nitrogen freezing trimmers to remove flash, burrs, and edges from rubber products, injection-molded products and metal castings.
HLH utilize advanced foreign technology, equipment, and unique technological innovations to process polycarbonate monofilaments into cylindrical micro-particles. These particles are uniform, have neat cross-sections, are anti-static, strong, and wear-resistant.
This product has a certain toughness and relatively higher hardness compared to other products in the same series.
It is used for cleaning burrs and overflow glue on the surfaces, holes, and recesses of plastic, bakelite, resin and other products without damaging the workpiece, and it has an exceptionally long service life.
You can choose the color of the nylon sand for deburring based on the color of
your product, with white and red being the most commonly used.
