Product Description

Higher cryogenic deflashing machine is used for deflashing of thermoset parts, rubber and silicon parts and metal die casts.

PRINCIPLE
With the decrease of the temperature, rubber/plastic parts enters into hardened, brittle, and crystallized process, its flexibility is gradually lost. It is easily broken by external force when it is under brittle temperature. Flash of the molded products is generally much thinner than finished product itself, it become brittle earlier than product in the low temperature. Cryogenic deflashing machine applies this principle, works in the time range when flash is brittle while products still keeps its flexibility, hit the flashes by high speed projected special plastic media, clear out the brittle burr. The flashes can be easily removed and the product not be damaged.

APPLICATION

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

Typical 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 & goggle

ADVANTAGES

• 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. Rather than replace or repair a mold (which typically involves downtime and high cost), the parts can be deflashed. This is typical of parts molded at the end of their product lifetime.
• The process is computer controlled, therefore removing the human operator variable from the process.
• The process offers consistent results lot to lot.
• Cryogenic deflashing is non-abrasive.
• Cost per part is generally well below any alternative techniqu
