This automation minimizes manual intervention, reducing labor requirements and associated costs. Furthermore, the high level of automation improves workplace safety by reducing human exposure to hazardous cutting environments.
Key Considerations When Selecting a Laser Cutting Machine for PEB
Choosing the right laser cutting machine is a strategic decision for any PEB company. Several critical factors must be carefully evaluated to ensure the investment yields optimal returns and integrates effectively with existing operations.
Laser Type: Fiber Lasers Dominating the Market
For industrial metal cutting, especially in PEB applications, fiber lasers have become the technology of choice. They offer superior cutting speed, energy efficiency, and lower maintenance requirements compared to older CO2 laser systems.
The power of the fiber laser (measured in kilowatts, kW) is a crucial consideration, directly impacting the maximum material thickness and cutting speed. For typical PEB steel components, systems ranging from 6kW to 20kW and beyond are often required to efficiently process thicker structural plates.
Machine Size and Bed Dimensions
PEB manufacturing frequently involves processing large steel plates and long profiles. Therefore, the cutting bed dimensions of the laser machine must be large enough to accommodate the typical sizes of raw materials used.
