Hardware molds, plastic molds, stamping molds, metal surface laser hardening

Laser quenching is a quenching technology that uses laser to heat the material surface above the phase transition point. As the material cools, austenite transforms into martensite, hardening the surface of the material.
Practical application
Laser quenching technology can strengthen the surface of various guide rails, large gears, journals, cylinder walls, molds, shock absorbers, friction wheels, rollers, and roller parts. Suitable materials are medium to high carbon steel and cast iron.
Characteristics of laser quenching
1. The quenched parts will not deform, and the thermal cycle process of laser quenching is fast.
2. The surface roughness is almost undamaged and a thin anti-oxidation protective coating is used.
3. Laser quenching will not crack, precise quantitative CNC quenching.
4. Precise CNC quenching can perform local, groove and groove quenching positioning.
5. Laser quenching is clean and efficient and does not require cooling media such as water or oil.
6. The quenching hardness is higher than the conventional method, the quenching layer structure is fine, and the strength and toughness are good.
7. Laser quenching is a rapid heating and self-induced cooling process that does not require furnace insulation or coolant quenching. It is a pollution-free, green and environmentally friendly heat treatment process that can easily achieve uniform quenching of the surface of large molds.
8. Due to the fast laser heating speed, small heat-affected zone, and surface scanning heating and quenching, that is, instant local heating and quenching, the processed mold deformation is very small.
9. Due to the small divergence angle and good directionality of the laser beam, the mold surface can be accurately partially quenched through the light guide system.
The depth of the hardened layer of laser surface quenching is generally 0.3-1.5mm.
