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.

  PPS PET and PA parts nitrogen deburring machine   Cryogenic deflashing and deburring is a process that employs cryogenic temperatures to remove flash on manufactured workpieces made of a wide range of plastics (and other materials) both thermoset and thermoplastic. Some examples of materials used include nylon, HD-PE, PPS, PET, polycarbonate, polypropylene, polyurethane, liquid crystal polymer, PA+GF, PC+GF, PEEK, and Acetal. Manufactured parts that have been successfully deburred include those made through injection molding, compression molding and extrusion molding.    What is “Flash.” “Flash” is a raised edge attached to the workpiece. It is an unwanted piece of material and requires removal. Many medical devices and other precision components are included in deflashing applications. Deburring accounts for a significant amount of the costs of manufacturing. The cryogenic deflashing process causes the flash or burr to become stiff or brittle and break away leaving a clean edge. There are three types of burrs that can be formed in manufacturing operations and can be classified by the physical manner of formation: Poisson burr, roll-over burr and Tear burr. ■Poisson Burr A Poisson burr results from the tendency of a material to bulge at the side when compressed until permanent deformation of the plastic occurs. ■Roll-over Burr A roll-over burr is a burr that is more of a chip that is bent rather that sheared. The resulting burr is usually comparatively larger. The process even removes recessed burrs in blind and through holes. ■Tear Burr A Tear burr is the result of material tearing from a work piece rather than shearing from it. In the cryogenic deflashing process, parts are loaded into a basket. A cryogem such as liquid nitrogen is used to cool the workpieces. After they are cooled they are tumbled with pellets- often a polycarbonate media ranging in size from 0.006 to 0.080 inches (0.15mm to 2.03 mm.) Sometimes cryogenic deflashing does not rely on a blasting action but rather on the tumbling of the parts to remove flash from the outer edges. The process can even remove recessed burrs in blind and through holes. The process does not affect the surface finish or the geometry of the part. Edges are maintained without rounding or removal of extra material and only the unwanted burrs are removed.   Cryogenic Deflashing Systems Advantages Cryogenic deflashing equipements provides advantages over manual deflashing. ■The process maintains part integrity and critical tolerances. As it is a bath process the price per piece is far less as many more parts can be processed at the same time. ■Cryogenic deflashing is non-abrasive. ■As the process is computer controlled, the human operator variable is removed from the process. ■Mold life is extended by the cryogenic deflashing process. Instead of making a new mold a company may choose to deburr a manufactured part cryogenically and achieve the same product quality very much as they would with a new mold for a period of time until maintenance is performed.   Pege’s Automatic Nitrogen Trimming Machine’s Features ■Greater productivity ■Large output in short time ■Better and consistent Finish ■Low Labour dependence ■Space Saving ■Low Media Consumption ■Wide variety of rubber compounds - NR to Silicon Rubber ■Low Nitrogen Usage ■Simple Electrical Controls ■High Efficiency Blast Wheel ■Safety Interlocks ■Simple and Very Low maintenance

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.
