Overview:
Manufacturing moulds and tools can be a costly process, and their service lives are often shortened due to wear and tear, damage, and corrosion. However, laser welding has emerged as a promising solution to significantly enhance the lifespan of moulds and tools through laser deposition welding. The Die Mould Laser Welding Machine, developed by SIL, offers exceptional performance and flexibility in this regard.
Our robust and high-performance Die Mould Laser Welding Machine enables the welding of intricate structures that would otherwise be challenging or even impossible to weld using traditional welding technologies. This is particularly advantageous when working with delicate materials such as plastic or glass. With precise control over laser energy and exposure time, the machine allows for welding of metallic materials with high melting temperatures and excellent thermal conductivity. Moreover, it possesses the capability to weld different types of metals, further expanding its versatility.
