Why laser for Die-Mould Making moulds and tools are expensive, and their service life can be shortened by wear & tear, damage and corrosion. Laser welding can significantly increase the life of molds and tools. With the help of laser deposition welding, user can easily modify design/change design, so that an old mold will not have to be replaced. Laser systems from SIL feature excellent performance and flexibility. With our robust, high-performance laser welding devices, we provide you a machine that allows complicated structure that are difficult or impossible with traditional welding technologies, even in the immediate vicinity of sensitive materials, such as plastic or glass. The good control of laser energy and exposure time allows welding of metallic materials with high melting temperatures and high thermal conductivity. It can even be used to weld different metals.
Laser Sources :
Application determines the choice of a laser source. SIL has Nd:YAG and Fiber Sources.
Based on the application, we can therefore advise you in finding the best solution for you.
High accuracy, the welding spot diameter is only 0.2mm-2mm
Little heat affected area, no distortion of the processing parts.
No effect for etch after welding, low oxidation rate, the color of the processing part is intact.
No stomata or sand hole disappeared after welding.
Can process at the welding point, especially applicable to repairing mould requiring polishing.
The processing parts can reach 50-60 Rockwell hardness.
