The Cryogenic Deflashing Process Cryogenic Deflashing is a process designed to remove molding flash created during the molding process. Molding flash can be found on molded parts along the parting lines, gate vestiges, and where pins and slides are located. In order for molded parts to complete their desired function, the residual molding flash needs […]
Rubber deflashing is the process of removing excess material called flash, or flashing, from the surfaces of molded rubber parts. The causes of flash are numerous and include parting line mismatches, improper venting, inadequate clamping pressure, poor sprue bushing support, and excessively low viscosity. No matter what the cause, old or worn tooling is often […]
What’s the difference between dry ice deflashing vs. cryogenic deflashing? Both are used to remove mold flash from plastic or rubber parts. Dry ice deflashing uses compressed air to propel a stream of solid carbon dioxide (dry ice) particles that blast away surface defects. Cryogenic deflashing uses gaseous nitrogen to freeze parts so that mold […]
Cryogenic deflashing removes flash, a type of surface defect, from molded rubber and molded plastic parts. This computer-controlled batch process provides faster cycle times, reduced labor costs, and greater part-to-part consistency than hand trimming.
Nitrofreeze® Cryogenic Deflashing provides part molders and OEMs with a fast, consistent way to remove flash from rubber components including natural rubber, silicones, EPDM, Polyurethane, Neoprene, Viton, Vamac,butylrubber, and more . Cryogenic deflashing uses gaseous nitrogen to freeze the parts, and plastic media to break-off the surface imperfections and excess material. This safe, clean process […]
