Rubber and plastic parts are placed in a stainless steel parts basket, which rotates in a blast chamber evenly exposing all parts to the blast media. The chamber is insulated with rigid polyurethane foam to ensure stable temperatures.
Liquid nitrogen lowers the interior temperature, freezing the flashing to make it brittle.
The high-speed impeller shoots polycarbonate plastic pellets into the chamber. Traveling at high speeds, these pellets cleanly trim off the inner and outer diameter flashing of parts in one operation. The unit is fully enclosed to minimize ambient noise levels. Blast media and flash can be separated and recovered for reuse. Benefits of This Unique Process Greater Productivity Cryogenic deflashing trims parts in seconds.
