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.
The medical device industry sets high standards and tight tolerances on all manufactured products. One specification, and maybe the most important, is surface finish.
Nitrofreeze® cryogenic deflashing removes flash from glass-filled PEEK coupling rings. This fast, efficient and consistent finishing process uses gaseous nitrogen to freeze the parts and plastic media to break-off surface imperfections and excess material. Because it’s a batch process, cryogenic deflashing eliminates manual deflashing such as hand trimming for faster throughputs and reduced labor costs. […]
