What is Cryogenic Deflashing / Deburring? And how can it
reduce cost?
- What is it?
- Cryogenic deflashing is the process of removing excess flash from
rubber and plastic parts super cool liquids and a media. The parts
that are to be deflashed / deburred are cooled to the embrittling point
of the material. Once brittle the parts are subjected to a blast
effect similar to a sandblaster. The media used is either a
plastic or metal of varying sizes. The size of the media is
dictated by many factors. The media then breaks off the excess
flash and can smooth rough edges.
- What materials can be deflashed / deburred cryogenically?
- The most common materials to be deflashed / deburred are plastics
and rubbers. The includes natural rubber and man-made rubbers.
From Neoprene to Silicone.
- What type of parts can be deflashed / deburred cryogenically?
- Almost any plastic or rubber part even some
metal parts can be deflashed / deburred in this fashion. The only
real criteria is that the flash has to be thinner than any area of the
part. Medical parts, automotive parts, o-rings, gaskets, etc.....
- Does cryogenic deflashing / deburring harm the parts?
- Freezing the material has not been shown to do any harm.
Rather, some customers are starting to research if the freezing may
actually be beneficial to the material.
- How can Cryogenic deflashing / deburring reduce cost?
- Not only does manual labor cost reduce but this process can reduce
the time to deflash / deburr. LEI machines typically run a single
load in approximately 5 minutes. It doesn't matter which
machine, the normal run is 5 minutes. That means that the CBD-6
will process 6 cu foot of parts in about 5 minutes. And the CMB-1
will process 1 cu foot in the same time.
