Cryogenic nitrogen deflashing is used to remove unwanted residual mold flash from newly molded or cast rubber and plastic parts. This die cast deflashing method utilizes cryogenic temperatures that cause the flash to become stiff or brittle and to break away cleanly, even from oddly shaped parts.
The use of cryogenic temperatures allows for precise removal of flash from materials including silicone, plastic, polymers, elastomers, rubber and aluminum die castings, all without degrading the parts or harming the finish. It is suitable for rubbers of various durometers and parts that have been injection molded, extrusion molded, or compression molded.

Deflashing machines and cryogenic temperatures are used to remove flash from a broad range of products, including:
O-rings & gaskets
Medical implants, surgical tools and devices
Electronic connectors, switches, and bobbins
Gears, washers and fittings
Grommets and flexible boots
Manifolds and valve blocks
Nanjing Pege Techno Machine Co., Ltd has been offering cryogenic deflashing to numerous industries for nearly 10 years. Our expertise, along with a wide variety of practical experiences, has allowed us to customize equipment, invent processes and master the art of turning your precision components into high quality, finished parts.

What Is the Freeze Trim Deflashing Process?
Deflashing machines use liquid nitrogen to help the utilized part reach a low enough temperature where its material becomes brittle. Once the material reaches a brittle state, the cryogenic deflashing machines are used to tumble and blast the part with polycarbonate or other media. This results in quick, easy and controlled removal of any residual mold flash. Cryogenic deflashing machines can also be used to alter or provide a polished or textured finish to a part’s surface.
Advantages of Cryogenic Deflashing Over Manual Removal Methods
Almost every plastic or rubber molding method leaves some form of residual flashing on a product. This issue can be more common in silicones rubber or similar materials that have a high viscosity. Manual flash removal is one common method, but it can be time-consuming and lack the consistency required for medical devices and other precision molded components.
Using cryogenic temperatures for plastic deflashing is an efficient and highly effective method that provides several advantages, including:
Computer controlled process provides higher accuracy than manual deburring
High level of consistency
Non-abrasive and will not damage finishes
Lower cost than other plastic deflashing methods
Maintains part integrity and critical tolerances
Lower price per piece
Extends mold life

Cryogenic Deburring Machine Installations in Worldwide Customers Factory
Cryogenic deflashing and deburring is a process that employs cryogenic temperatures to remove flash on manufactured workpieces made of a wide range of rubber and plastic (and other materials) both thermoset and thermoplastic. Some examples of materials used include nylon, Tefzel®, HD-PE, PPS, PET, polycarbonate, polypropylene, polyurethane, liquid crystal polymer, ABS, Peek and Acetal. Manufactured parts that have been successfully deburred include those made through injection molding, compression molding and extrusion molding.
Cryogenic deflashing machines are known for its precise quality de-flashed parts with up to 95% performance output without affecting the final part dimension and shape from small O-rings to big molded parts.These Machines serve the need for Rubber, Metal-Rubber parts, small precision plastic parts and small die-casting parts like Zinc and Magnesium alloy.
Cryogenic De-burring Machine aims at realizing faster quality production cycle with least rejection on those parts including rubber molded, plastic injection molded and die-casting components' flashes removal process.
Cryogenic deflashing/deburring machine is applied to deflash or remove the flashes of polyurethane bumpers for Automotive shock absorption.
