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.
