Cryogenic Deflashing & Deburring


Arrow Cryogenics has been offering cryogenic deflashing and deburring to numerous industries since 1983. Our expertise, along with a wide variety of cryogenic deflashing machines, has allowed us to customize equipment, invent processes and master the art of turning your precision components into high quality, finished parts.

Cryogenic deflashing and deburring is one of the most efficient and cost-effective processes to remove flash from injection molded parts and burrs from machined components. This process can be completed on a wide variety of materials, including rubber, plastic, silicone and light metal die castings.

Cryogenic Deflashing for Metal Parts

Cryogenic deflashing removes unwanted residual mold flash from newly molded rubber and plastic parts. This deflashing method utilizes cryogenic temperatures to aid in the removal of flash on cast or molded workpieces. These temperatures cause the flash to become stiff or brittle and to break away cleanly. Cryogenic deflashing is the preferred process when removing excess material from oddly shaped, custom molded products. The cryogenic deflashing process does not degrade the parts or harm their finish.

Cryogenic Deflashing Materials & Applications

There are numerous types of materials and applications that can be utilized by cryogenic deflashing, these include:

Materials for Cryogenic Deflashing

A wide range of molded materials can be deflashed with great precision:

  • Silicone
  • Plastic
  • Rubber
  • Die Casting

Applications for Cryogenic Deflashing

Typical examples of applications that use cryogenic deflashing include:

  • O-rings & gaskets
  • Medical implants, surgical tools and devices
  • Electronic connectors, switches, and bobbins
  • Gears, washers and fittings
  • Grommets and flexible boots
  • Manifolds and valve blocks

The Cryogenic Deflashing Process

The use of liquid nitrogen within the cryogenic deflashing process allows the utilized part to reach a low enough temperature where its material becomes brittle. The cryogenic deflashing machine is then able to quickly and easily remove flash from the part without altering its finish. This is accomplished by tumbling and blasting the part with media once it is cooled. It is also possible to alter or provide a polished or textured finish to a part’s surface through the cryogenic deflashing process.

Advantages Associated with Cryogenic Deflashing

Cryogenic deflashing provides a wide range of benefits over other types of deflashing methods, these include:

  • The process is computer controlled, therefore removing the human operator variable from the process.
  • The process offers consistent results from lot to lot.
  • Cryogenic deflashing is non-abrasive.
  • The cost per part is generally well below any alternative technique.
  • The process maintains part integrity and critical tolerances.
  • Since it is a batch process, the price per piece is far less as many more parts can be processed in a given amount of time.
  • Cryogenic deflashing extends mold life.

Cryogenic Deburring

A raised edge of excess material on a metal part, called a burr, is the result of performing a machining operation such as grinding, milling, drilling or turning. Removing this burr is called deburring. Cryogenic deburring of components increases their safety, quality and functionality. Cryogenic deburring is much more economical and efficient than labor intensive hand deburring. You can save time, cost, and have consistent quality using cryogenics for deburring.
