Nitrofreeze® provides deflashing services for EMI parts including shielding gaskets and O-rings. These environmental seals and EMI shields are made of electrically conductive silicones, elastomers that are filled with metal or metal-coated particles to provide protection against electromagnetic interference (EMI), a growing problem with electronic devices and electrical equipment At our Worcester, Massachusetts (USA) facility, […]
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 […]
Medical silicones can be molded into parts such as distal handles for surgical instruments and dental tools. There are many types of silicone rubber, but medical grade silicones need to meet biocompatibility requirements such as USP Class VI or ISO 10993. Then, after they are molded, medical silicone parts need to have a finish that’s […]
Nitrofreeze® cryogenic deflashing removes flash from silicone bumper stops. This fast, consistent and cost-effective process uses gaseous nitrogen to freeze the parts and plastic media to break-off surface imperfections and excess material. Thanks to batch processing, cryogenic deflashing can also reduce lead times and labor costs. The Challenge Nitrofreeze was asked to remove flashing from […]
Nitrofreeze® cryogenic deflashing provides part molders and OEMs with a fast, consistent way to remove flash from silicone distal handles. 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 is also cost-effective because it supports batch processing. The report below […]
