Why Medical Injection Molding Uses Cryogenic Deflashing

Medical injection molding supports the use of a wide variety of plastic and rubber materials. Examples include PEEK, polycarbonate, and LSR – just to name a few. During the injection molding process, excess material known as flash can escape the mold and mar part surfaces. The causes of flash are numerous and include parting line […]

The Five T’s of Cryogenic Deflashing Molded Parts

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 […]

Cryogenic Deflashing for Plastic Parts

Cryogenic deflashing for plastic parts is an automated batch process that removes mold flash, excess material that affects surface quality and can cause problems with sealing and assembly. During  cryogenic deflashing, molded parts are put in a perforated drum, subjected to cryogenic temperatures, and blasted with plastic media. The cryogen, a gaseous nitrogen, embrittles the […]

Cryogenic Deflashing – How It Works

Cryogenic Deflashing offers a modern approach to remove flash from your parts created during the molding process. The cryogenic deflashing process removes flash from parts via tumbling and blasting of fine, polycarbonate media in a cold atmosphere. By subjecting the parts to cold temperatures, the flash becomes brittle and is easily removed when the media […]
