Nitrofreeze® cryogenic deflashing is a quick, consistent, and cost-effective way to remove flash from batches of molded rubber and plastic parts. Flash, a type of manufacturing defect, is excess material that forms on the surfaces of parts produced with injection, compression, or transfer molding. Flash detracts from a part’s appearance, but it can also cause […]
Nitrofreeze® cryogenic deflashing removes mold flash from parts produced using silicone rubber overmolding, a multi-step process that molds silicone rubber over parts made from another material. Examples include medical devices where silicone is molded over metal to provide protection against water, heat, impact, and electrical shock. Silicone can also be molded over plastic during two-shot […]
Nitrofreeze® cryogenic deflashing for plastic insert molding gently removes flash from parts and products like electrical connectors and surgical tools. During insert molding, a plastic or rubber material is molded over a substrate that has been inserted into the mold. In the case of an electrical connector, this substrate is an electrically conductive metal. The […]
Introduction to Cryogenic Deflashing Cryogenic deflashing is a process used to remove excess material or flash from molded components. Flash refers to thin protrusions or excess material that are often formed during the manufacturing process due to mold imperfections or parting lines. Cryogenic deflashing is particularly useful for removing flash from plastic and rubber components. […]
Introduction Buna-N, also known as Nitrile rubber) is a synthetic rubber polymer made from the copolymerization of acrylonitrile and butadiene. It is one of the most commonly used elastomers due to its excellent resistance to oils, fuels, and chemicals. Buna-N rubber has a high resistance to abrasion and is also highly durable, making it an […]
