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.

The path to a sustainable hydrogen economy is full of challenges
To effectively protect the climate, we need to significantly reduce the share of fossil fuels in the energy mix and promote the further expansion of renewable energies. Hydrogen is seen as one of the most promising forms of renewable energy. If climate neutrality is the goal, it can significantly reduce carbon emissions, leaving the power sector far behind. In Germany alone, there will be hydrogen plants with a total installed capacity of up to 10 GW by 2030, and KSB is providing advanced solutions to achieve this goal.
We spare no effort in the development of hydrogen energy
Hydrogen technology will play a key role in the future energy supply as it has many advantages. Firstly, "green" hydrogen produced using electrolysers is carbon neutral and relatively simple to produce. Electrolysis is the process of splitting water molecules (i.e. H2O) into hydrogen and oxygen at the cathode and anode using electricity (in this case from renewable sources such as wind, hydro or photovoltaics). The two gases are separated and processed for further use. Hydrogen produced in this way can be used for a wide range of applications, such as storing energy, producing climate-neutral fuels, powering vehicles or as a raw material for the steel and chemical industries.
As a solution for compact containerized electrolysers: The flow rates here are around 10 m3/h.
Choosing the right pumps and valves is crucial in the transition to hydrogen. As an experienced manufacturer in the field of industrial and chemical processes, we have a broad product portfolio and extensive expertise in systems engineering, operating modes, materials and energy efficiency.
We have the perfect product for every production technology for green hydrogen. Our solutions are compatible with all major green hydrogen production technologies – from alkaline electrolysis (AEL) and proton exchange membrane electrolysis (PEM) technologies to future technologies such as anion exchange membrane electrolysis (AEM) or high-temperature electrolysis (HTEL). Of course, as a full-service supplier with comprehensive expertise, we also offer ideal solutions for the production of blue, grey or blue-green hydrogen.
Whichever process wins out in the future and which production scale or type of electrolyser proves to be more efficient, KSB will be able to cope with it because its product portfolio covers all stages of the hydrogen value chain and different Power-to-X technologies (including the production, transportation, storage and use of hydrogen).
In addition to our research activities and extensive funding projects, we also keep a close eye on emerging hydrogen business models and technologies. These initiatives are aimed at developing this technology for a greener future and driving the development of the hydrogen economy. We are committed to creating a greener future together with you. Welcome to the world of green solutions!
