- • Perform laser cladding repair treatment for cracks, scratches, abrasions, collapses, etc. that occur during the use of the mold.
- • The mold can be processed by laser quenching, laser melting and hardening, laser cladding (repair) and laser alloying.
- • Laser cladding is realized without preheating the mold or subsequent heat treatment. The cladding surface is smooth and flat, and is metallurgically combined with the mold body. The hardness of the cladding layer can meet the requirements of different hardness levels according to the process requirements of the user’s mold. After covering, only a small amount of machining molds can be directly put into use.
- • In view of the user’s large mold size, easy local wear and other characteristics that require high-precision repair, laser cladding alloy powder has been specially developed.
- • According to the user’s mold shape and size and its requirements for heat treatment and cladding process, special processing software is compiled, which can meet the buyer’s current laser heat treatment and cladding process requirements for all molds; after appropriate adjustments to the processing software and process, it can Meet the laser heat treatment and cladding process requirements of plastic molds and other types of molds and other types of parts that the buyer needs to process in the future.
- • For special-shaped mold workpieces (inside and outside), high-reflectivity gold-plated copper mirrors (including total reflection focusing system) are used to achieve laser heat treatment, which makes the focusing system low in cost, long in life, and easy to maintain.
Laser quenching and cladding repair process index of mold
- • The range of mold size for laser quenching and cladding repair ≥ 3000×2000×1000 (mm)
- • Quenching hardness ≥HRC58 (for 45# steel)
- • Hardened layer thickness ≥1mm
- • Quenching speed 25mm broadband scanning, speed ≥1500mm/min
- • Cladding hardness: It can be arbitrarily controlled between HRC15-62.
