Nitrofreeze® cryogenic deburring is a fast, safe, and consistent way to remove burrs from batches of machined parts. During cryogenic deburring, parts are cooled below the material’s glass transition temperature (Tg) so that burrs become brittle and easy to remove. Parts are then blasted with a specified cryogenic-grade polycarbonate media that comes in different diameters […]
Cryogenic deflashing and vibratory tumbling can both remove flash from molded plastic or rubber parts. Both finishing processes are machine-based and put batches of molded parts inside a drum or barrel, where the parts come in contact with an application-specific media. Beyond these basic similarities, cryogenic deflashing and vibratory tumbling are very different mass finishing […]
Rubber deflashing is the process of removing excess rubber known as flash from the surfaces and edges of molded parts. During rubber injection molding, flash is caused by parting line mismatches, improper venting, inadequate clamping pressure, excessively low viscosity, or poor sprue bushing support. Tooling and processing issues can also cause mold flash during injection […]
Teflon machining is used to produce components for the aerospace, electrical, medical, and processing industries. Filled and unfilled grades of this fluoropolymer are used in machined parts such as beads, bushings, and bearings; seals, gaskets, and O-rings; gears, guides, and fittings; and valve bodies and valve seats. Machined Teflon is also used for arc shields […]
Deflashing for Overmolded Connectors Nitrofreeze provides deflashing services and equipment for overmolded electrical connectors. Overmolded electrical connectors protect wires, cables, sockets and other electrically conductive components against environmental conditions such as dust, moisture, weather, and heat. Overmolding, an injection molding process, molds a polymer such as Bakelite over these electrical components. Bakelite combines high electrical […]
