Die Mould Laser Welding Machine

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.

BENEFITS & FEATURES

• Real Time power feedback , compares output power and desired output power & accordingly controls the input of lamp bump, to control the output power. This feature helps in achieving power accuracy & results in linear & stable power throughout the welding process.
• SIL welding machine uses fiber for laser delivery. The laser output head is easy to install, easy to operate & user friendly.
• The laser welding machine can be integrated with coaxial CCD monitor system thus increase the processing efficiency & increase the production.
• Standard length of fiber is 5M. Others can be 3M or 10M.
• Fiber core diameter: 200 µm, 300 µm, 400 µm, 600 µm, 800 µm

Advantages

• 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.
