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

We have processed parts made of various durometers. We typically deflash rubber parts made of EPDM, neoprene, Viton, Buna-N, nitrile, natural gum, SBR, butyl, and other elastomers. Our Cryogenic Deflashing machine is often used by molders who work with silicone rubber. Silicone rubber, by its nature, is very viscous causing it to flash during the molding process. The Pege’s Deflashing machine removes mold flash from silicone rubber parts. We deflash parts made of liquid silicone rubber and even special blends of silicone rubber that include conductive fillers such as silver, graphite, nickel. Rather than invest in an expensive new or repaired mold tool, customers can elect to extend the functional life of their mold tool by adding the additional step of deflashing, to finish the part and remove any residual flash leftover after molding operations. It is economical to pay only a slight premium per part than to invest in a new molding tool that has a limited production life.         Cryogenic Deflashing is a fast and efficient process that provides complete removal of mold flash without affecting the surface finish. Therefore, it is a safe,clean and cost-effective alternative to traditional methods. Parts are placed in a chamber, cooled, tumbled and impacted with plastic polycarbonate media. Mold flash is removed quickly and cleanly. No dust or residue remains after deflashing. Cryogenic Deflashing is more cost-effective than labor-intensive hand deflashing by a significant margin. The cost to process parts can range from less than .01 cent to several dollars apiece. General rule of thumb: cost is between 10% and 20% of the value of the part, although each part must be considered on its individual   Nanjing Pege’s Cryogenic Deburring Machine’s ADVANTAGES 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   Our factory and Workshop of cryogenic deflashing systems Nanjing Pege Techno Machine Co.,Ltd production plant is located in the No.9 Ankang road, Guli Industrial Zone, Jiangning District, Nanjing.We have professional production workers and process, are determine to produce best product for the customer all over the world   Packing and Transportation of cryogeic deflashing equipments The machine produced by Nanjing Pege is well packed by plywood carton suitable for long distance sea transportation to ensure machine safety and performance.

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.

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. Overall, cryogenic deburring offers advantages in terms of precision, non-destructiveness, versatility, efficiency, environmental impact, and cost-effectiveness, making it a favorable choice for rubber deflashing processes in various industries.
