effect of laser cutting technology on mold design and manufacturing
Laser cutting technology uses a focused high-energy-density laser beam to irradiate the workpiece, causing the temperature of the irradiated part of the workpiece to rise sharply, the material to melt and vaporize rapidly, and at the same time, the molten material is blown away by high-pressure gas coaxial with the beam to form a slit to cut the workpiece. Laser cutting technology has great advantages:
①) Laser cutting is a non-contact processing, the workpiece has no mechanical deformation, the laser beam has little effect on the non-laser irradiated parts, its heat-affected area is small, and the workpiece has little thermal deformation.
②) Laser cutting is fast and efficient, with a cutting speed of up to 10,000 mm/min. The entire cutting process does not require clamping and fixing, which can save both tooling and fixtures and auxiliary time for loading and unloading.
③) Laser cutting has good quality and high precision, the slit surface is smooth and beautiful, the surface roughness value is generally controlled at Ra=12.5um, and the positioning accuracy can be controlled at 0.05mm~0.01mm
4) Laser cutting has good flexibility function, and the entire cutting process is fully CNC-controlled. It can perform both two-dimensional cutting and three-dimensional cutting. By simply changing the CNC program, it can be used to cut parts of different shapes. It is not affected by the shape of the workpiece and can process any graphics.

(1) Laser cutting is directly utilized for the blanking of small batches and multi-variety chassis parts, eliminating the need for blanking molds in order to reduce mold development costs.
(2) The mold development cycle for new products is shortened by employing laser cutting in the blanking, middle trimming, and punching processes, effectively reducing the time required to determine mold test sizes. This not only meets product requirements but also expedites mold setup and saves on mold opening time.
(3) For the blanking of high-strength steel plates and complex spatial shapes of large workpieces, laser cutting is preferred over using molds due to lower manufacturing and maintenance costs. However, stamping dies are still necessary for mass production of small and medium-sized workpieces where the cost of laser cutting technology is higher.
(4) In the process of mold manufacturing, some parts that were originally cut by flame are now directly cut by laser without requiring additional processing. Additionally, certain components such as plates can be directly laser-cut into finished products, resulting in savings on mold manufacturing costs. 
When the mold is a small batch trial order, the cost of the stamping machine is very expensive. At this time, high-precision products can use cutting machines instead of stamping machines to save costs for customers and improve trail order processing time
