Cryogenic deflashing is a deflashing process that uses a system whereby parts are placed in a chamber, exposed to extremely cold temperatures (achieved with the use of liquid nitrogen) and then tumbled and blasted with a polycarbonate media. Because the burrs have a high surface area relative to their mass, they “freeze” very quickly and become brittle. The tumbling action—combined with the impact of the media—removes the burrs without damaging the part itself.

Cryogenic deflashing is the preferred process when removing excess material from oddly shaped, custom molded products.

Process

Parts are loaded into a parts basket. A cryogen, such as liquid nitrogen, is used to cool the workpieces; once cooled they are tumbled and blasted with media pellets, ranging size from 0.006 to 0.080 inches (0.15 to 2.03 mm). In some instances, cryogenic deflashing does not utilize a blasting action, relying instead only on the tumbling of the parts to remove flash on the outer edges.

Applications

A wide range of molded materials can utilize cryogenic deflashing with proven results. These include:

Silicones

Plastics – (both thermoset & thermoplastic)

Rubbers – (including neoprene & urethane)

Liquid crystal polymer (LCP)

Glass-filled nylons

Aluminum zinc die cast

Examples of applications that use cryogenic deflashing include:

O-rings & gaskets

Catheters and other in-vitro medical

Insulators and other electric / electronic

Valve stems, washers and fittings

Tubes and flexible boots

Face masks & goggles
