China is gradually emerging as an international hub for processing and manufacturing, driving a growing demand for metalworking. In the metalworking industry, electrical control boxes and machine housings—commonly made from sheet metal—are particularly in high demand, which in turn is continuously boosting the need for advanced sheet-metal fabrication capabilities. As a result, the processes involved have become increasingly complex, with some components requiring as many as dozens of individual工序. This complexity, coupled with stringent precision requirements, places even greater demands on the quality and expertise of sheet-metal machining.

As a result, the processes involved have become increasingly complex, with some components requiring as many as dozens of individual工序. This complexity, coupled with stringent precision requirements, places even greater demands on the quality and expertise of sheet-metal machining.
Traditional sheet metal processing involves processes such as shearing, punching, and bending. Among these, the punching process requires a large number of molds, leading to significant waste of both time and financial costs.
Laser cutting is an efficient, high-quality, and flexible manufacturing process. Laser sheet metal fabrication eliminates the need for molds, making it simpler to operate, more versatile than traditional methods, and significantly reducing operational and maintenance costs.
Newwei Laser has innovatively upgraded its years of accumulated laser cutting technology, introducing a range of advanced laser cutting equipment that delivers efficient and professional laser-based sheet metal processing solutions to the industry—ultimately helping customers maximize their value.
Traditional sheet metal cutting equipment and process flow
The conventional processing method for stainless steel involves a sequence of cutting, punching, bending, and welding—or alternatively, flame or plasma cutting followed by bending and welding. However, when faced with orders that demand multiple varieties, small batch sizes, customization, high quality, and short lead times, this approach clearly falls short:
· (CNC) shear machines, due to their primarily linear cutting capability, can only be used for sheet metal processing that requires straight cuts;
· (CNC/Brick Tower) Punch presses have limitations when cutting steel plates thicker than 1.5 mm, resulting in poor surface quality, high costs, significant noise levels, and environmental concerns.
·Flame cutting, as the original traditional cutting method, results in significant thermal distortion during cutting, wide kerf widths that lead to material waste, and slow processing speeds—making it suitable only for rough machining.
·High-pressure water cutting has a slow processing speed, leading to significant pollution and high operational costs.
New-Generation Sheet Metal Cutting Equipment and Process — Laser Cutting
The advantages of the new sheet metal cutting process include:
·Laser cutting offers high flexibility, fast cutting speeds, and superior productivity, resulting in short product turnaround times. Whether dealing with simple or complex parts, laser technology enables rapid, one-step shaping and cutting.
·Narrow cutting seams, excellent cutting quality, high automation, simple operation, low labor intensity, and zero pollution;
· Enables automatic cutting layout and nesting, improving material utilization while eliminating tool wear and offering excellent material compatibility.
·Low production costs and strong economic benefits.
Laser cutting represents a revolutionary advancement in sheet metal processing—it’s essentially the “machining center” of the industry. This technology boasts remarkable advantages, such as flexibility and versatility. As traditional sheet metal cutting methods continue to face challenges, the demand for laser cutting is steadily rising.
Ruijin cylinders are primarily used as supporting components for large and medium-sized enterprises. Since their users have diverse product requirements—often demanding high quality and urgent delivery—we recommend utilizing high-power, large-format laser cutting machines. These machines not only enhance cutting performance but also significantly improve cutting efficiency. Additionally, their expansive working area maximizes material utilization while seamlessly meeting the unique demands of various materials.
