Why cryogenic deflashing machines are becoming more and more popular?
The use of cryogenic deflashing machines has revolutionized the way manufacturers produce high-quality products. Cryogenic deflashing machines use liquid nitrogen to remove excess material from manufactured parts. The process is fast and precise, making it ideal for mass production. In this article, we will explore the advantages of cryogenic deflashing machines and why they replace traditional manual deflashing methods.
First of all, using a cryogenic deflashing machine is environmentally friendly. This makes Operating Room safer, healthier choice for workers and the environment.
Secondly, cryogenic deflashers require less maintenance than traditional deflashing methods. This is because high quality spare part enable the machine to operate for a long time and do not require frequent replacement or maintenance.
Thus, these machines save the manufacturer time and business cost.
Thirdly, the cryogenic deflashing machines provide higher deflashing precision and accuracy. The process is controlled and consistent, ensuring that each pitch is finished to a high standard. This is useful for products that require smooth edges, such as medical instruments, automotive components, and electronic equipment.
Finally, the cryogenic deflashing machines are versatile. They are available in a wider range of materials including rubber, injection molding (including elastomeric materials) and zinc magnesium aluminum die casting. This flexibility means they can be used in a variety of industries, making them a valuable investment for many companies. All in all, the advantages of low temperature deburring machines make them an excellent choice for manufacturers. They are environmentally friendly, require less maintenance, provide greater precision, and are versatile. The cryogenic deflashing machines are becoming more and more popular in the manufacturing industry as technology advances and machine designs improve. They are likely to continue to be popular as manufacturers seek to produce high-quality products efficiently and cost-effectively.
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 Pegedeflashing 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 cryogenic deflashing 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.
Cryogenic Deflashing Machine Product and Company Introduction
Cryogenic deflashing machines are known for its precise quality de-flashed parts with up to 95% performance output without affecting the final part dimension and shape from small O-rings to big molded parts.
These Machines serve the need for Rubber, Metal-Rubber parts, small precision plastic parts and small die-casting parts like Zinc and Magnesium alloy.
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.

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.
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. How to know if the product is suitable for cryogenic deflashing？

On the year of 2022, one customer from Colombia sent some samples for testing. The rubber parts to be deflashed are rubber O rings.
You can see from following photo:
There are many flashes which are difficult for manual deflashing.
After Cryogenic deflashing, we can get good results without flashes.
Even though the deflashing result was acceptable, customer was hesitating to make decision to purchase the cryogenic deburring machine due to the budget problem.
They paused the purchase this nitrogen shot blasting deflashing machine.
On the year of 2025, last year, customer restarted the project and we talked about the model and the offer and finally we made a deal to sell the cryogenic deflashing equipment Model PG-60T to customer.
It is a wonderful machine for automatic rubber deflashing process, it is well designed and well manufacturered.
