Jiangsu Minnuo Oxygen Generator: The Efficient Gas-Production “Power Core” for Laser Cutting

In modern industrial manufacturing, laser cutting has become the mainstream process in the metal processing field due to its advantages of high precision, high speed, and low loss. It is widely used in engineering machinery, automobile manufacturing, sheet metal processing, aerospace, and other industries. The stable operation and cutting quality of laser cutting are inseparable from the supply of high-quality, continuous, and stable oxygen. As a key auxiliary gas for laser cutting, oxygen not only supports combustion to increase the cutting temperature but also blows away slag and avoids incision oxidation. Its purity and pressure stability directly affect cutting efficiency and workpiece precision. With years of experience in the gas equipment field, Jiangsu Minnuo has independently developed an oxygen generator with core advantages of “on-demand gas production, controllable purity, stability, and high efficiency.” It has become the preferred gas source solution for the laser cutting industry, providing strong support for enterprises to reduce costs and increase efficiency.

I. Core Oxygen Requirements for Laser Cutting: Why Choose Jiangsu Minnuo Oxygen Generator?

In the laser cutting process, the quality and supply stability of oxygen directly determine the success of the process. The traditional mode of purchasing bottled oxygen or liquid oxygen has been difficult to meet the high-efficiency production needs of modern industry:

• Strict purity requirements: The oxygen purity must reach 99.5%. Insufficient purity will lead to severe oxidation of the incision, increased slag adhesion, rough cutting surface, and even laser head wear.
• Uninterrupted supply: In continuous production, gas source interruption will cause production downtime, resulting in material waste and construction period delays.
• Precise and stable pressure: The oxygen output pressure needs to be maintained at 0.6-1.2MPa (adjusted according to the cutting material and thickness). Pressure fluctuations will lead to inconsistent incision width and reduced cutting speed.
• Cost control needs: Purchasing liquid oxygen involves transportation losses, storage risks, and its price is greatly affected by market fluctuations, resulting in high long-term use costs.

Adopting advanced Pressure Swing Adsorption (PSA) technology, Jiangsu Minnuo Oxygen Generator can accurately match the gas demand of laser cutting, outputting industrial oxygen with adjustable purity of 93%-99.5%. It also features “instant startup and production, continuous supply, and constant pressure,” completely solving the pain points of traditional gas supply modes and providing stable and reliable gas source guarantee for laser cutting.

II. Core Advantages of Jiangsu Minnuo Oxygen Generator in Laser Cutting

1. High-Purity Gas Production to Ensure Cutting Quality

Equipped with high-quality molecular sieves and a precision filtration system, Jiangsu Minnuo Oxygen Generator can effectively separate impurities such as nitrogen and carbon dioxide in the air. The output oxygen purity is stably maintained at 93%-99.5%, fully meeting the oxygen purity requirements for laser cutting. High-purity oxygen ensures full combustion of fuel during the cutting process, rapidly melting metal materials, while reducing the thickness of the incision oxide layer. This results in a smooth and flat cutting surface with no slag adhesion and good perpendicularity, eliminating the need for subsequent grinding and significantly improving workpiece qualification rates. For example, in the cutting of stainless steel plates, when using oxygen with 99.5% purity, the surface roughness of the incision can be controlled below Ra12.5μm, and the qualification rate is increased by more than 30% compared with cutting with ordinary low-purity oxygen.

2. Uninterrupted Stable Supply to Improve Production Efficiency

Compared with the frequent cylinder replacement of bottled oxygen and transportation delays of liquid oxygen, Jiangsu Minnuo Oxygen Generator can be directly connected to the gas source pipeline of laser cutting machines to achieve 24/7 continuous gas production. The equipment is equipped with an intelligent pressure control system, which can automatically adjust the output pressure and flow according to the real-time gas demand of laser cutting. The pressure fluctuation range is controlled within ±0.01MPa, avoiding cutting interruptions or quality defects caused by unstable pressure. Meanwhile, the oxygen generator supports a multi-unit parallel design. For large-scale laser cutting production lines, multiple devices can be linked to ensure full coverage of gas source supply, increasing production efficiency by 20%-40%. It is particularly suitable for batch processing and continuous operation scenarios.

3. Energy Conservation and Consumption Reduction to Lower Comprehensive Costs

Adopting a high-efficiency and energy-saving compressor and an optimized adsorption process, Jiangsu Minnuo Oxygen Generator has an energy consumption of only 60%-70% of traditional oxygen generation equipment. The production cost per cubic meter of oxygen is as low as 0.3-0.5 yuan, which is much lower than that of purchased bottled oxygen (about 1.5-2 yuan/cubic meter) and liquid oxygen (about 0.8-1.2 yuan/cubic meter). Taking a 100Nm³/h oxygen generator as an example, operating 20 hours a day and 300 days a year, it can save about 180,000-360,000 yuan in gas source costs annually, with an equipment investment payback period of only 1.2-2 years. In addition, the oxygen generator does not require special storage equipment and covers a small area (about 3-5㎡ per unit), reducing safety risks and labor costs in transportation and storage links, and further lowering the comprehensive operational burden of enterprises.

4. Intelligent and Convenient, Adapting to Industrial Scenarios

Jiangsu Minnuo Oxygen Generator is equipped with a full-Chinese intelligent control system, supporting one-key start/stop, parameter setting, fault alarm, and other functions. Operators can easily operate it without professional skills. The equipment is equipped with a remote monitoring module, allowing real-time viewing of oxygen purity, pressure, flow, equipment operation status, and other data through a mobile APP or computer terminal. When an abnormality occurs, an alarm message is automatically sent to facilitate timely maintenance. Meanwhile, the core components of the oxygen generator (molecular sieves, solenoid valves, sensors) are all high-quality imported products. The continuous operation failure rate of the equipment is less than 0.3%, and the service life is as long as 8-10 years. It also supports customized design, which can tailor the adaptation plan according to the model, production capacity, and gas parameters of the laser cutting machine to meet the cutting needs of different industries and specifications.

III. Typical Application Cases: Jiangsu Minnuo Oxygen Generator Empowers the Laser Cutting Industry
