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 […]
Glass-filled nylon parts are injection molded into precise shapes for industrial, medical, electronic, automotive, and aerospace applications. Nylon, a generic name for a category of synthetic polymers, support the production of strong, durable parts; however, nylon typically has poor resistance to heat and ultraviolet (UV) light. The addition of glass fibers to nylon improves these […]
Medical injection molding supports the use of a wide variety of plastic and rubber materials. Examples include PEEK, polycarbonate, and LSR – just to name a few. During the injection molding process, excess material known as flash can escape the mold and mar part surfaces. The causes of flash are numerous and include parting line […]
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 Deflashing Challenge Injection molding flash, or flashing, is excess material that is forced out of a mold cavity at the parting line or ejector pin locations. This surface defect mars the finish of molded parts and can interfere with their performance. Traditionally, injection molders remove flash by hand. However, manual trimming is slow, time-consuming, […]
