What is Sheet Laser Cutting?
Laser cutting is a manufacturing process that uses a high-power laser beam to cut, engrave, or mark materials — typically sheet metal, plastics, wood, or composites. The laser melts, burns, or vaporizes the material along a programmed path, leaving a clean, precise edge.
Laser cutting uses a focused, high-power laser beam to precisely cut sheet metal and other materials with narrow kerf, clean edges, no tooling cost, and high speed — ideal for prototypes, low-to-medium volumes, and complex 2D profiles.
What’s advantages of Laser Cutting?
High Precision and Accuracy
Laser cutting delivers exceptional precision, typically holding tolerances of ±0.003–0.005 inches (±0.08–0.13mm). The focused beam creates fine cuts for intricate details, small holes, and complex contours, reducing or eliminating secondary finishing.Sheet metal parts are strong and durable but relatively lightweight — ideal for structural applications where weight matters (aerospace, automotive).
Minimal Material Loss
Low-cost prototyping with laser cutting (no tooling). For production, stamping dies reduce per-part cost significantly. Easily scales from prototypeThe laser beam creates a narrow cut width of 0.004–0.012 inches (0.1–0.3mm) — much smaller than plasma (0.060–0.120"). With nesting software, this achieves 80–90% material utilization, significantly reducing scrap and raw material costs. to high-volume runs.
High Cutting Speed
Laser cutting is extremely fast on thin sheet metal, with typical speeds of 10–30 meters per minute (330–980 ft/min) for materials under 3mm thick. This translates to shorter lead times, higher throughput, and lower cost per part compared to waterjet, plasma (on thin materials), or conventional machining.
Cuts Hard and Reflective Materials
Fiber lasers cut hardened steels (HRC 50–65), stainless steel, aluminum, brass, and copper — materials that destroy conventional cutting tools or cannot be machined after heat treatment. Laser cutting has no hardness limitation for conductive materials, making it ideal for pre-hardened components.
No Tooling Cost
Unlike stamping or punching, laser cutting requires no dies, punches, or hard tooling. This eliminates tooling fabrication time (days to weeks) and costs ($1,000–$100,000+), making it highly economical for prototypes and low-to-medium volumes (1–5,000 parts) with no penalty for design changes.
Clean Edges with Minimal Burrs
The laser melts and vaporizes material cleanly, producing smooth, burr-free edges directly from the machine. In most cases, no secondary deburring is needed — saving time and labor, especially for parts that will be welded, painted, or assembled.
Laser Cutting Capabilities from Prototyping to Mass Production
Laser Cutting
Fiber laser cutting is a modern sheet metal process that uses a fiber-delivered laser beam to cut, engrave, or mark conductive materials. Thanks to its higher efficiency, lower maintenance, and superior performance on reflective metals, it is widely adopted in industrial cutting — typically handling thin to medium-thick plates up to 25mm
It can typically cut various metal materials such as carbon steel, stainless steel, aluminum, brass and copper, etc.
CO2 Laser Cutting
CO₂ laser cutting is a manufacturing process that uses a gas laser — a mixture of carbon dioxide (CO₂), nitrogen, and helium — to generate a high-power infrared laser beam (10.6 µm wavelength) for cutting, engraving, or marking materials.
CO₂ lasers were the dominant technology for metal cutting before fiber lasers emerged. Today, they remain the first choice for non-metal materials and are still used for certain metal cutting applications, especially consider cost is a primary concern.
