Most frequently asked question regarding the technology of the cryogenic deflashing    1. What is cryogenic deflashing? Deflashing machines use liquid nitrogen to help the part reach a low enough temperature where its substrate becomes protected. Once the excess flash or burrs reach a brittle state, the cryogenic deflashing machines are used to tumble and blast the part with polycarbonate or other media to remove the unwanted flash.   2. Does cryogenic deflashing work on molded plastic parts? Yes. The process removes burrs and flash on plastics, metals, and rubber.   3. Can cryogenic deflashing remove internal and microscopic burrs? Yes. The cryogenic process combined with the appropriate media in the deburring machine removes the smallest burs and flashing.   4. What are the advantages of cryogenic deflashing? Deflashing is an efficient and highly effective method that provides several advantages, including: ·   ♦ 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 ·   ♦ Use low cost cryogenic deflashing to avoid repairing your expensive mold. ·   ♦ Computer controlled process provides higher accuracy than manual deburring   5. What kind of products are able to be cryogenically deflashed? 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   6.

Consumables for cryogenic trimming machine – supply of liquid nitrogen   The frozen cryogenic deflashing machine, as an essential auxiliary manufacturing machinery in the production process of rubber enterprises, has been indispensable. However, since its entry into the mainland market around the year 2000, local rubber enterprises have little knowledge of the working principles and processes of the frozen trimming machine. Therefore, this article will provide a detailed introduction to the storage and supply methods of the cryogen, liquid nitrogen, for cryogenic deflashing machine. In the past, liquid nitrogen was typically stored in separate liquid nitrogen tanks. Therefore, when purchasing a cryogenic trimming machine, it was necessary to buy a matching liquid nitrogen tank to ensure the proper operation of the machine. The installation of the liquid nitrogen tank required approval from the relevant authorities, which was a cumbersome process, and the tanks themselves were expensive. This has led many factories that urgently need to use cryogenic deflashing machines to improve work efficiency to hesitate, as it also involves a certain upfront cost investment. Nanjing PEGE has introduced a liquid nitrogen manifold supply station to substitute for liquid nitrogen tanks. T his system centralizes the gas supply of individual gas points, enabling multiple low-temperature Dewar flasks to be combined for centralized gas supply. It solves the cumbersome process of handling liquid nitrogen tanks, allowing customers to operate the frozen edge trimming machine immediately after purchase. The main body of the system simultaneously connects three bottles of liquid nitrogen Dewar flasks, and it also includes a port that can be expanded to accommodate four bottles. The system pressure is adjustable and equipped with a safety valve. It’s easy to assemble and can be mounted on the wall using a triangular bracket or placed on the ground using the bracket.

Nanjing Pege Cryogenic Deflashing Machines  PRODUCT DESCRIPTION PROCESSING PRINCIPLE With the decrease of the temperature, rubber/plastic parts enter into hardened, brittle, and crystallized process, its flexibility is gradually lost. It is easily broken by external force when it is under brittle temperature. Flash of the molded products is generally much thinner than finished product itself, it become brittle earlier than product in the low temperature. Cryogenic deflashing machine applies this principle, works in the time range when flash is brittle while products still keeps its flexibility, hit the flashes by high speed projected special plastic media, clear out the brittle burr. The flashes can be easily removed, and the product not be damaged.   FUNCTIONS Our cryogenic deflashing machine is widely used in removing the flashes of small rubber and plastic parts like O-rings, gaskets and other press molded or injection moulding parts. With the cryogenic processing technology, the flashes are firstly frozen and then blasted down by the high-speed projection media (Polycarbonate media). The surface quality of molded rubber and plastic rubber parts can be improved greatly while the product are not damaged.   APPLICATIONS  A. O rings, irregular rubber parts with different material and sizes.  B. Micro electronic product parts  C. Precision elastomeric parts  D. Precision injection moulding plastic parts  E. R & D part runs  F. Die casting products, like zinc aluminum, magnesium alloy   FEATURES High efficiency: The automatic rubber deflashing machine can replace about 60-80 worker to removing the flashes. High precision: It can remove small and hardened flashes which cannot be removed by handworkers and improve precision of the products. Low cost: It also has a feature of lower cost comparing with processing the parts by handworkers.
