Die Laser Quenching
Use German IPG 4000W Fiber Laser to quench on varies automobile die.
The width of Light spot is 10-30 mm; power density spreads evenly; the hard layer of quenching is 1.0-1.5 mm; the hardness of quenching area is HRC55-62.
The common materials for automobile die quenching include:
Ductile cast iron：GGG70L 2070 190 245 246
Cast steel class：1.2379 1.2358 A2 D2
Die steel：CR12MOV H13
The advantages of laser quenching to repair automobile die are: higher speed of the laser quenching process on automobile dies, less temperature change of total die, and smaller metal crystal in metallographic structure than other quenching techniques, no shape change. The abrasion resistance increased significantly.
