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.

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.

The definition, principal, and composition of a typical Cryogenic Deflashing Machine A cryogenic deflashing machine, also known as a cryogenic deburring system, is a type of equipment used to remove excess material or flash from molded or machined parts. Cryogenic deflashing is a process that involves the use of extremely low temperatures to freeze the parts and then removing the flash using various methods. The cryogenic rubber deflashing machine typically consists of a large chamber or tub where the parts are placed. Liquid nitrogen  is used to rapidly cool the parts, making them brittle. Once the parts are sufficiently cooled, they are subjected to tumbling or blasting action, which causes the brittle flash to break off from the parts. The rubber or plastic flash is then separated from the parts using air, vibration, or other means. Cryogenic deflashing is commonly used in industries such as automotive, aerospace, electronics, and medical devices, where precision and cleanliness are critical. It is an effective and efficient method for removing flash from complex-shaped parts without damaging the component itself. Moreover, cryogenic deflashing is considered to be environmentally friendly compared to traditional methods that involve the use of harsh chemicals or mechanical trimming. Nanjing Pege Techno is a leading supplier of various type of cryogenic deflashing machines.

When the feeder is running, the motor drives the feeding screw, vibrator or pump to move. At the same time, the material in the measuring hopper flows out. By reducing the weight in the unit time, obtain the actual feeding amount, compare it with the set feeding amount to get the error value, and then adjust the speed of the feeding motor through the PID closed-loop control algorithm to achieve the precise feeding requirements. This process ensures an accurate feeding or dosing during the production process. The general purpose of Loss in Weight feed system is to accurately weigh and control the output of variable products either, continuously or as a batch. Benifits Typical loss–in-weight feeders are used to negate the use of weigh hoppers and to eliminate the impact of material. This system is particularly useful when the product to be weighed is sticky and does not have good flow properties. A. Improve measurement accuracyB. Reduce premixing workloadC.
