How to repair the damaged mold:
1. Argon arc welding repair
The welding is carried out by using the burning arc between the continuous welding wire and the workpiece as the heat source and the gas protection arc emitted by the torch nozzle.
2. Mold repair machine repair
Die mending machine is a high-tech equipment for repairing die surface wear and processing defects. The die mending machine has the advantages of long service life and good economic benefits.
3. Brush plating repair
Brush plating technology adopts a special DC power supply equipment, the positive pole of the power supply is connected to the plating pen as the anode during brush plating; the negative pole of the power supply is connected to the workpiece as the cathode during brush plating, the plating pen usually uses high-purity fine graphite block as the anode material, and the graphite block is wrapped with cotton and wear-resistant polyester cotton sleeve.
4. Laser surfacing repair
Laser welding is a kind of welding which uses the laser beam formed by focusing the high power coherent monochromatic photon flow as the heat source. This welding method usually includes continuous power laser welding and pulse power laser welding. The advantage of laser welding is that it does not need to be carried out in vacuum, but the disadvantage is that the penetration force is not as strong as that of electron beam welding.
5. Laser cladding technology
Laser surface deposition technology is a surface strengthening method which can rapidly heat and melt the alloy powder or ceramic powder and the substrate surface under the action of laser beam. After the laser beam is removed, the self-excited cooling will form the surface coating with extremely low dilution ratio and metallurgical combination with the substrate material, so as to significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical characteristics of the substrate surface.
