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.

Pege’s Cryogenic Deburring Machine Features ■Visual& Intelligent HMI Panel - User friendly 11inch HMI operation panel, one stop operation mode, can record and read the parameters, easy to operate and manage。 ■Robust Machine Frame - Frame is all made of 304 stainless steel, its edge uses red powder coating process to ensure both durability and elegant appearance. ■Compact Design to Save LN2 Consumption - To optimize the machine design to make sure the machine chamber is compact and small for saving liquid nitrogen to lower running cost. ■Greater Insulation Effect - Despite of using 75mm thicker insulation material, the insulation material is strengthened by SUS304 material, to ensure excellent heat preservation effect, also can lower LN2 consumption largely. ■Higher Blasting Speed with Big Diameter Wheel Ensure Great Power - Different wheel size choices ensure perfect match between power and barrel capacity to realize best processing result and highest productivity. Our 80Liter use a Ф300mm wheel with a max 7000rpm speed, and 120Liter&150liter a 350mm wheel with a max 7000rpm speed. ■Durable and Efficient Vibrator-Reliable customized SUS 304 vibrator can keep stable running for more than 10 years in the low temp, high humidity environment without failure. ■Bigger Diameter Sieve for Better Separation-Bigger capacity model(120liter&150liter’s) vibrator sieve diameters are around 600mm, which is larger than most of other manufactures, has the advantage of quicker filtering flash and media and has higher efficiency. ■Automatic Media Suction and Blasting- Automatic media circulation system by negative pressure occurred in machine inner chamber, not by screw lifter, save media and more intelligent. ■World Well-known Controller brand like SIEMENS, Panasonic or Mitsubishi, Omron to ensure high working stability in the low temp environment.■Easy and Convenient Media Exchange system to make operation quicker and easier. ■Better Gear Box Design and use customized anti-low temp oil seal to ensure very few dusts get into the box, so less maintenance on gear box. ■More Durable Umbrella Gear and Bearings will ensure long term consistent running with less failure and less maintenance cost. ■Robust Barrel and Machine Door-use strong and thick steel for barrel and machine doors, deformation will not happen even after long time use.
