Plastic molding can produce parts with flash, excess material that forms on part surfaces. During injection molding, molten plastic may escape through the mold’s parting line. Improper venting, low clamping pressure, low material viscosity, and uneven flow can also cause flash formation. In addition, injection molding flash sometimes occurs after the gate runners are removed. […]
Nitrofreeze® cryogenic deburring removes burrs from PEEK gears without affecting part geometry or surface finish. Unlike other burr removal methods, cryogenic deburring removes only the surface imperfections left behind by machining. The edges on gear teeth are maintained without unwanted rounding, and the Nitrofreeze® process can deburr challenging geometries and hard-to-reach areas. Keep reading to […]
Nitrofreeze® cryogenic deflashing removes flash from injection-molded PPS parts without affecting critical dimensions or surface finish. This proven process removes gate vestiges, flash that extends from the surface of an injection-molded part after gate runners are removed. Cryogenic deflashing also removes flash from hard-to-reach areas such as cross-holes, blind holes, and other challenging part geometries. […]
Medical plastics machining can produce complex parts with excellent dimensional stability. During CNC machining operations, however, milling and drilling can stretch part surfaces. If the workpiece material contains a crack, this stretching may cause the crack to grow and fracture. This creates burrs, raised areas that can interfere with part seating, sealing, or assembly. Nitrofreeze® […]
Medical plastic injection molding can produce high volumes of tight-tolerance parts for medical devices and equipment. During the injection molding process, however, excess material known as flash can form on the surfaces of parts. Cryogenic deflashing can safely, cleanly, and cost-effectively remove this unwanted plastic flash without affecting critical part tolerances. There are many other […]
