Laser cutting systems

Laser cutting systems from Europe, the United States, and Japan have been in use for decades. It wasn’t until the early 2000s that Chinese lasers gained recognition, particularly in die-making. Today, over 2,500 steel rule dies manufacturers worldwide rely on laser cutting technology.

Types of Laser Movement Systems in Cutting Die Construction
Laser machines for cutting formes production employ four distinct movement systems:

1. Moving Head: The laser head moves along both the X and Y axes.

2. Moving Table: The table shifts in the X and Y directions while the laser remains stationary.

3. Hybrid: One axis (typically longitudinal) moves the table, while the transverse axis adjusts the laser nozzle.

4. Flying Optics: The laser beam is directed via mirrors to any position across the table.

Each system has its strengths and weaknesses, yet all remain widely used in mold-making due to their unique benefits.

CO2 Lasers: A Staple in the Industry

CO2 lasers have been the go-to choice since the technology’s inception and were still prevalent in the late 1990s. Over time, innovations like "sealed-off" and "slab" designs reduced gas consumption and maintenance needs. Pioneering brands such as Coherent (which later absorbed Rofin Sinar), Ferranti, Feha, Cutlite-Penta, PRC, and Fanuc became industry standards. While some brands, like Trumpf, are less dominant in die-making, they excel at cutting steel and plastic.

Alternatives to Laser Cutting

For cutting grooves in wood, alternatives to laser technology include CNC saws (increasingly sourced from China) and CNC milling (suitable for both flat and rotary molds). These methods offer two key advantages: simpler maintenance and a cleaner working environment.

Environmental Considerations in Die-Cutting

The die-cutting industry is facing growing pressure to address environmental concerns, particularly exhaust fume filtration. Past attempts faltered due to inadequate oversight, but modern, proven filtration solutions now exist. It’s only a matter of time before such measures become mandatory—though the cost may catch some by surprise.

The Future of CO2 Lasers

CO2 lasers remain the fastest and most effective option for cutting slots in multiplex plates (die-boards). While fully automated alternatives for steel rule processing and bending exist, traditional processes continue to hold their ground in cutting die production.
