Laser hardening process coating equipment

Compared with the traditional heat treatment technology, the laser hardening process has many advantages, from an economic point of view, it improves working efficiency, productivity and product quality. In many applications, partial processing and small amount of heating can reduce the deformation, and the rapid cooling can produce good microstructure.

Metal sheet forming die

Metal sheet forming dies are widely used in the whole industrial field. The contact surfaces of the sheet can cause serious wear, especially for high-contacted pressure and radius of sliding areas. The laser hardening process can be used to replace the flame or induction from problems of deformation and reliability.

Laser hardening is well-suited for precision applications and rapid processing time of contact surface hardening to achieve minimum heat input, minimum deformation. Products with a length of more than 5M can be traced to 25mm width, 3mm depth hardening treatment. The flexibility of the laser equipment can be applied to all components in various shapes with hardening treatment process.

Plastic injection mould

Now, more and more plastic injection moulds are formed by laser hardening process. Because of growing service life, it requires the edge of tools to be hardened. The conventional mould, whether it is segmented or overall shape, the weight can reach 10 tons or more.

During the operating process, high injection pressure (~ 1000 bar) leads to a high degree of wear and tear, especially when the plastic is abrasive. These parts wear will cause edge burrs, often require repeated tedious manual removal. When compared with laser hardening treatment, the flame or induction hardening process can not achieve the desired effect, it also has limitations for the complex shape of moulds.
