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？
Sample Deflashing Tests We invite you to send us some of your parts for sample deflashing tests. This will enable you to review the quality of deflashing our equipment can achieve. In order for us to establish parameters for the parts you send, please identify each, by your part number, the main compound used in the manufacturing, along with a finished or Q.C. example. We use this as a guide to your expected quality level
Consumables for cryogenic rubber trimming machine – supply of liquid nitrogen
The frozen rubber deflashing machine, as an essential auxiliary manufacturing machinery in the production process of rubber enterprises, has been indispensable.
However, since its entry into the China mainland market around the year 2000, local rubber enterprises have little knowledge of the working principles and processes of the cryogenic deflashing machines.
Therefore, this article will provide a detailed introduction to the storage and supply methods of the cryogen, liquid nitrogen, for the cryogenic deflashing machines.
In the past, liquid nitrogen was typically stored in separate liquid nitrogen tanks. Therefore, when purchasing a cryogenic deflashing 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 machiness 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.
This cryogenic deflashing 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 cryogenic deflashing machines immediately after purchase. Above are good options for the container of the Liquid Nitrogen.
The main body of the cryogenic deflashing 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.
Nanjing PEGE always provide strong technical support for customer to better use the cryogenic deflashing system.
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.

For heating and cooling systems: Individual challenges require individual solutions
Clean air and the right air humidity and temperature: Creating an optimal indoor climate is the basic prerequisite for comfort and efficiency – for humans and machines alike.
Whether it’s a family home, an office complex or a computer centre: Every building is different and presents specific challenges in the planning and implementation of an optimal heating, air conditioning and ventilation system. Effective and efficient HVAC systems require suitable, individual components that are matched to one another.
The challenges vary depending on the building project, but the requirements placed on the components remain the same. The pumps and valves used should function reliably, quietly and have a long service life.
In addition to functionality, however, the economic and ecological parameters of heating and cooling systems in building technology are equally important. The efficient use of energy is one of the most important topics.
