Dry Ice Deflashing removes flash on the exterior and interior of parts and cleans cross-holes and slots within the parts. The process is effective in removing minor flash from parts.
Dry Ice Deflashing is an ideal solution for parts that have inconsistent flash. Since the parts are deflashed separately, attention is given to the areas of concern. If a work holder is required, NitroFreeze is expert in developing low-cost fixtures to support the deflashing of the parts.
Dry Ice Deflashing is available for most molded parts, especially on engineered materials and composites.
We have many cases of successful flash removal on parts machined from plastics, polymers, nylons, Delrin, Teflon, polypropylene, polycarbonate, ABS, PET, HDPE, PEEK, DAP, Tefzel, PPS, Viton, Torlon, CTFE, and Liquid Crystal Polymer.
The cost to deflash parts as a general rule of thumb is between 10% and 20% of the value of the part, although each part must be considered on its individual characteristics. Dry Ice Deflashing is more cost-effective than labor-intensive hand deflashing by a significant margin. Our automated process produces consistent part-to-part results, unlike variations produced by individual operators attempting hand deflashing.
Solid blocks of dry ice (CO2) or dry ice pellets are used as a non-abrasive media. The dry ice blasting system is connected to a compressed air source which achieves blasting at rates as high as 150 PSI. Once the dry ice impacts the surface, it sublimates, causing it to expand 800 times its original size. This allows the flash to be easily removed.
