The Main Compositions of A Cryogenic Deflashing System A cryogenic deflashing machine, also known as a cryogenic deflashing system, is used for removing unwanted burrs, flash, or excess material from molded or machined components. The composition of a cryogenic deflashing system generally includes the following components: 1. Deflashing Chamber: This is the main working chamber where the components to be deflashed are placed. It is usually a sealed, insulated enclosure designed to withstand low temperatures. 2. Liquid Nitrogen (LN2) Supply: Cryogenic deflashing relies on liquid nitrogen as the cryogenic medium. The LN2 supply provides the necessary cooling agent required for the process. 3. LN2 Delivery System: This system is responsible for delivering liquid nitrogen to the deflashing chamber. It typically consists of supply lines, valves, and control mechanisms to regulate the flow of LN2. 4. Control Panel: The control panel houses the electrical and electronic components that control and monitor the cryogenic deflashing process. It includes temperature controllers, timers, pressure gauges, and safety features. 5. Media Circulation Mechanism: Some cryogenic deflashing machines incorporate an auto media circulation system to realize the media blasting function and then enhance the deflashing process. This can be in the form of tumbling barrels, rotating baskets, or oscillating fixtures. 6. Exhaust System: As cryogenic  deflashing process generates gases and vapors, an exhaust system is employed to remove these by-products from the deflashing chamber. It helps maintain a safe working environment and prevents the accumulation of hazardous substances. 7. Filtration System: To remove any debris or particulate matter generated during the deflashing process, a filtration system may be included. It helps ensure the cleanliness of the liquid nitrogen and prolong the equipment's lifespan. 8. Safety Features: Cryogenic deburring machines often have safety features such as emergency stop buttons, alarms, and interlocks to ensure operator safety during operation.   It's important to note that specific configurations and features of cryogenic deflashing systems may vary depending on the manufacturer and the intended application.

Cryogenic Deflashing is a Good Method for Rubber Deflashing   Cryogenic deflashing is considered a good method for rubber deflashing due to several reasons: 1.     Precision: Cryogenic deflashing process is a controlled process that can remove flash from rubber components with high precision. It targets the unwanted excess rubber precisely without damaging the desired part geometry. This ensures consistent and accurate results. 2.     Non-destructive: Cryogenic deflashing machine is a non-destructive process, meaning it does not damage or weaken the rubber components during deflashing. This is important for maintaining the structural integrity and functionality of the parts. 3.     Versatility: Cryogenic deburring can be used for a wide range of rubber components, regardless of their shape, size, or complexity. It is suitable for both simple and intricate parts, making it a versatile option for various rubber products. 4.     Efficient: nitrogen shotblast deflashing is a relatively fast process, allowing for high-volume production. The use of liquid nitrogen or other cryogenic media rapidly freezes the rubber parts, and subsequent tumbling or blasting breaks off the flash, ensuring efficient deflashing. 5.     Environmentally-friendly: Cryogenic rubber deflashing is an environmentally-friendly process compared to traditional deflashing methods. It does not involve the use of harsh chemicals or generate harmful waste. Cryogenic media, such as liquid nitrogen, evaporates during the process, leaving no residue behind. 6.     Cost-effective: While cryogenic shotblast deflashing may initially require an investment in specialized equipment, it can be a cost-effective solution in the long run. It reduces labor-intensive manual deflashing and minimizes the need for post-production rework or scrap due to damaged parts.

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.
