Cryogenic Deflashing – How It Works


Cryogenic Deflashing offers a modern approach to remove flash from your parts created during the molding process. The cryogenic deflashing process removes flash from parts via tumbling and blasting of fine, polycarbonate media in a cold atmosphere. By subjecting the parts to cold temperatures, the flash becomes brittle and is easily removed when the media comes across the surface of the parts.

The Cryogenic Deflashing process offers a unique way for companies to remove burrs from parts. In a matter of a few short steps the process is complete.

  1. Parts are loaded into a basket, which is then loaded into the deflashing system.
  2. Liquid nitrogen flashing to gaseous nitrogen is pumped in to machine.
  3. Once operating temperature is achieved, parts begin to tumble against one another while media is blasted at the parts.
  4. After the cycle is completed a post tumble process begins, which removes any residual media from the parts.
  5. Once the post tumble is complete, the basket is removed from the system and the parts are put in a work holder where they are allowed to dry.

The Cryo Deflashing process provides many benefits to companies that need to remove residual flash from their parts. Benefits include the following results.

  1. Provides repeatable method to deflash parts
  2. Increases production throughput
  3. Does not charge surface finish
  4. Does not affect critical tolerances
  5. Eliminates the need for hand deflashing
  6. Reduced cycle times (minutes not hours)
  7. Lower or eliminate scrap yields

The Cryogenic Deflashing process is suitable for parts molded of various materials including plastics, polymers, nylons, rubbers, silicone rubber, polyurethane, neoprene, liquid crystal polymer, urethane, Viton, Buna-N, polycarbonate, PTFE, PPS, delrin, polypropylene, EPDM, nitrile, butyl, DAP, ABS, PEEK, and Acetal, among others.
