Cryogenic deflashing for molded silicone parts removes flash for improved appearance and performance. Mold flash is often a cosmetic defect, but silicone molders want to avoid the appearance of surface imperfections that suggest poor quality. With parts such as silicone gaskets or O-rings, flash that affects a part’s surface finish can interfere with proper sealing. The causes of flash are numerous, but molders and manufacturers who use cryogenic deflashing can achieve consistent, high-quality results.
Silicone mold flash can be trimmed by hand, but manual deflashing is labor-intensive and time-consuming. Hand trimming is also inconsistent since different workers may achieve different results. There can even be part-to-part differences by the same worker during the same shift. Outsourced deflashing might seem expensive, but cryogenic deflashing is an automated, computer-controlled batch process that can save silicone molders and manufacturers time and money.
