HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Recently, in the demonstration workshop of the NUZHUO Technology Service Center, a cutting test aimed at evaluating the practical application capabilities of PSA (Pressure Swing Adsorption) oxygen generators attracted much attention. As the operator started the laser cutting equipment, a PSA oxygen generator independently developed by NUZHUO began to supply gas on-site. Within just a few seconds, a 10mm-thick carbon steel plate was perfectly cut. The cutting surface was smooth, flat, free of slag and burrs, and was unanimously recognized by the representatives of the on-site customers.

The customer uploaded a video that was over three minutes long, sharing the joy of the successful cutting.

This test aims to verify the gas supply quality and stability of the NUZHUO oxygen generation equipment in the laser cutting scenario. The auxiliary gas used in the cutting process has extremely high requirements for purity, pressure and dew point. Ordinary industrial oxygen cannot meet the needs of precise processing. At the test site, this oxygen generator continuously outputs oxygen with a stable purity of 93% ± 2%, with pressure fluctuations not exceeding ± 0.05 MPa, and a dew point lower than -40℃. It continuously provides clean, dry and high-concentration oxygen to the laser cutting head throughout the process. During the cutting process, the oxygen is fully used for combustion, the molten metal is discharged smoothly, the verticality of the 10mm sheet section is good, the roughness is controlled within Ra6.3, and it fully meets the quality standards of the precision processing industry.

From a technical perspective, this PSA oxygen generator adopts an imported zeolite molecular sieve and dual-tower alternating adsorption process, combined with the independently developed intelligent pressure equalization technology. This effectively enhances the oxygen recovery rate and the operational efficiency of the equipment. The device is equipped with a 7-inch touch screen human-machine interface, supporting one-click start/stop, real-time parameter monitoring, and historical data export. The operation is convenient, and the entire machine occupies less than 2 square meters of space, making it suitable for flexible deployment in various processing workshops.

The NUZHUO technical engineer gave a live presentation, stating that compared to the traditional liquid oxygen tank supply mode, the on-site PSA oxygen generation can help users reduce their oxygen usage costs by approximately 40%. At the same time, it eliminates the safety risks associated with liquid oxygen storage and transportation as well as the hassle of changing tanks. The excellent performance of cutting 10mm steel plates this time further confirms the reliability and applicability of NUZHUO’s oxygen generation equipment in the metal processing field.

It is known that this client is an enterprise engaged in the processing of mechanical engineering components. Previously, due to unstable oxygen quality, the cutting yield was relatively low. After on-site investigation and field testing, the client was highly satisfied with the performance of the NUZHUO equipment and reached a preliminary purchase intention on the spot. The relevant person in charge of NUZHUO stated that they will continue to focus on the laser cutting and oxygen supply support field, and provide better gas solutions to help manufacturing customers reduce costs and increase efficiency.

The successful actual measurement of the 10mm steel plate cutting this time not only serves as a powerful demonstration of the performance of NUZHUO PSA oxygen generator products, but also reflects the significant progress made by domestic industrial gas equipment in the field of precision manufacturing and assembly. As laser processing technology continues to evolve towards higher power and higher speed, end users have increasingly strict requirements for the quality of auxiliary gases and the stability of gas supply. The on-site oxygen generation mode is gradually becoming the mainstream alternative to traditional oxygen supply methods. NUZHUO, with its solid molecular sieve filling process, precise airflow distribution design, and complete after-sales service system, has accumulated rich practical experience in multiple application scenarios such as laser cutting, flame cutting, and metal heat treatment. In the future, NUZHUO will continue to increase its research and development investment, promoting the iterative upgrade of oxygen generation equipment towards higher purity and lower energy consumption, and providing more competitive gas solutions for industries such as sheet metal processing, shipbuilding, and automotive parts manufacturing, helping Chinese manufacturing move more steadily and further on the path of quality improvement and efficiency enhancement.
