If you mold or machine rubber, plastic or metal, cryogenic deflashing can dramatically increase throughput and processing speed. C.D.S.'s deflashing systems are compact, easy to install, and much more efficient than manual deflashing or rotary tumbling. The result is faster order processing with reduced labor costs.

Benefits ......................................................................................................
• Greater productivity.
C.D.S.'s deflashing machines trims parts in seconds. This is much faster than chemical stripping, molten salt baths, incineration, rotary tumbling, and hand sanding. As a result, more parts can be deflashed in less time.

• Better product quality.
The high temperatures of molten salt baths and incineration can distort parts. C.D.S.'s deflashing systems keeps parts cold to preserve their integrity. Use of plastic blast media prevents the scratching caused by hand sanding and blasting with abrasive such as sand, steel shot, aluminum oxide or glass beads.

• Environmentally sound.
The nitrogen cryogen can be recycled or vented safely to the atmosphere. The use of toxic chemicals and the problems associated with their disposal are completely eliminated. In addition C.D.S.'s systems are typically enclosed to minimize noise.

• Improved plant safety.
C.D.S.'s deflashing systems prevents the splashing that can occur when using a molten bath. It also gets rid of toxic fumes and dust associated with chemical stripping and manual deflashing.

• Simple operation.
Highly automated, today's C.D.S.'s systems are easy to use. All systems are configured to deflash rubber, plastic, and metal products in a wide range of materials, sizes and shapes, either cryogenically or ambiently. Compact design permits installation even when space is limited.

How it works .............................................................................................
Rubber and plastic parts are placed in a stainless steel perforated basket and inserted in a blast chamber. The basket rotates to evenly expose 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. Use of high-purity, moisture-free nitrogen eliminates the need for a dryer and prevents part contamination.

A high-speed impeller shoots polycarbonate plastic pellets into the basket. Traveling at high speeds, these pellets cleanly trim off the inner and outer diameter flashing in one operation. Optimized hardness and lubricity minimize impeller wear to extend useful operating life.

The unit is fully enclosed to minimize ambient noise levels. Blast media and flash can be separated and recovered for reuse.
