Cyrogenic deflashing removes mold flash from plastic and rubber parts for improved appearance and performance. There are three different versions of this surface finishing process. The first, known simply as cyrogenic deflashing, freezes parts and blasts them with plastic media. The second, cyrogenic tumble deflashing, combines the advantages of cryogenic deflashing with dry ice deflashing, […]
Dry ice blasting for parts finishing is a non-abrasive process that removes flash and burrs from individual molded or machined parts. Learn about its advantages, and when to use it instead of cyrogenic deflashing and deburring.
Molding defects reduce the surface quality of rubber and plastic parts. The causes include problems with flow lines, sink marks, vacuum voids, and surface delamination. Molding defects are also caused by short shots, burn marks, jetting, and warping. Flash or flashing, the formation of excess plastic or rubber on the surface of molded parts, is […]
Cryogenic deflashing for molded rubber parts removes mold flash from hard-to-reach areas such as cross-holes, blind holes, and other difficult geometries. During the rubber molding process, flash or flashing can occur anywhere that metal meets metal – especially as mold tooling wears. Rubber molders can remove these surface defects through hand or manual deflashing, but […]
Cryogenic deburring and cryogenic deflashing are versatile processes that improve the surface quality of plastic or rubber parts that have been machined or molded. This article explains how Nitrofreeze optimizes these cryogenic processes.
