I. The “Oxygen Code” of Laser Cutting: Purity and Stability Determine Processing Limits
As a core processing technology in modern industry, the efficiency and quality of laser cutting depend critically on the performance of auxiliary gases — especially for mainstream metal materials such as carbon steel and cast iron, where oxygen serves a role far beyond the basic function of “blowing away molten slag.” With years of experience in the industrial oxygen generation sector, Jiangsu Minnuo is well aware that for every 2% drop in oxygen purity, the laser cutting speed decreases by 50%. In contrast, high-purity oxygen with a concentration of over 99.5% can trigger a full iron-oxygen combustion reaction, releasing additional heat to form a “laser + oxidation” dual heating effect, thereby increasing cutting efficiency by 20%-30%.
In terms of technical parameters, laser cutting has targeted requirements for oxygen: a pressure of 0.6-0.8MPa is needed for cutting 1-3mm thin plates, which increases to 1.0-1.2MPa for 5-10mm medium-thick plates, while the oxygen consumption for 22mm thick carbon steel can reach 10m³/h. Traditional supply modes such as bottled oxygen or liquid oxygen not only face issues like pressure fluctuations and unstable purity but also incur high transportation and storage costs, becoming an invisible bottleneck restricting production efficiency.
II. Jiangsu Minnuo Oxygen Generator: Addressing Three Core Industry Pain Points in Laser Cutting
To meet the rigorous demands of laser cutting, Jiangsu Minnuo has developed exclusive industrial oxygen generation solutions using advanced PSA (Pressure Swing Adsorption) technology, fundamentally resolving the industry’s key challenges:
1. High Purity and Stability to Ensure Cutting Quality
The equipment stably delivers high-purity oxygen with a concentration of 99%-99.5%, fully meeting the purity requirements of laser cutting and avoiding problems such as dross adhesion and oxidative blackening of cut edges caused by impurities. Equipped with an intelligent pressure stabilization system, the pressure fluctuation is controlled within ±0.1MPa, ensuring thorough removal of molten slag during thick plate cutting and achieving a cutting surface finish of Ra≤1.6μm, meeting precision cutting standards.
2. High Efficiency and Energy Conservation to Reduce Comprehensive Costs
Compared with bottled oxygen, Minnuo’s on-site oxygen generators eliminate the need for transportation and storage, reducing gas costs by 30%-50% in long-term use. For example, a medium-sized processing plant equipped with an oxygen generator with a flow rate of 30-100Nm³/h can save hundreds of thousands of yuan annually. Meanwhile, the equipment adopts frequency conversion energy-saving technology, with energy consumption 15% lower than the industry average. Combined with automatic start-stop functionality, it further reduces unnecessary energy consumption.
3. Flexible Adaptability to Cover Full-Scenario Needs
Jiangsu Minnuo offers a full range of oxygen generation equipment, from small units (10-30Nm³/h) suitable for laser cutting machines below 6kW to large systems (>100Nm³/h) supporting ultra-high-power equipment above 12kW. All can be precisely matched according to the thickness of the cutting material and equipment power. With a footprint of only 1-15m², the equipment is easy to install and supports remote monitoring. Maintenance only requires regular filter replacement, significantly lowering operational thresholds.
III. Selection Guide: Jiangsu Minnuo Teaches You to Precisely Match Oxygen Generation Solutions
Choosing a dedicated oxygen generator for laser cutting should follow the principle of “demand-oriented.” Jiangsu Minnuo provides professional selection recommendations:
- Thin plate processing (<3mm): Recommend small oxygen generators (10-30Nm³/h) with a pressure adaptation of 0.6-0.8MPa to meet rapid cutting needs;
- Medium-thick plate processing (3-20mm): Select medium-sized equipment (30-100Nm³/h) with high-pressure output of 1.0-1.5MPa, combined with dual-nozzle protection function;
- Ultra-thick plate/high-yield scenarios (>20mm): Customize large-scale integrated nitrogen-oxygen generation systems with a flow rate >100Nm³/h, supporting 24/7 continuous operation and adapting to high-precision production needs in automotive manufacturing, construction machinery, etc.
