Laser Mold Repair Welding Machine

YAG Laser Spot Welder for Mould Repair

Mold laser welding machine is mainly used for repair of large and medium-sized molds. It is widely used in mobile phones, digital products, automobiles, motorcycles and other mold manufacturing.

Mold Repair Laser Welding Machine

The laser mold repair welding machine can quickly and accurately repair the pores, slag holes, and shrinkage holes formed during the casting process. Suitable materials for laser repair include ductile iron, gray iron, stainless steel, etc.

The laser welding machine for mold & die Repair is specially designed for the mold industry and is utilized in the restoration of precision molds made of materials such as gold and silver. It finds applications in various mold manufacturing, including electronics, mobile phones, toys, automobiles, motorcycles, and other molding industries. The laser mold repair technology effectively addresses all welding and repair tasks for small components, overcoming the limitations of traditional argon arc welding techniques in repairing and welding fine surfaces. This mold repair welder avoids the challenges of thermal strain and post-processing, significantly reducing the mold production cycle.

Applications of laser welding industrial molds
1. Edge repair
2. Hole repair
3. Restoration of worn edges
4. Welding of small components
5. Addition of shim materials
6. Tool maintenance
7. Porosity repair

Laser Mould Welding Machine Advantages:
1. By welding workpiece axis X/Y/Z/D for stepping drive, meet the needs of the big trip.
2. Repeated positioning precision, fast welding speed and high efficiency.
3. Automatic focus and rotation function weld products of any shape 3D space.
4. Tailored four axes linkage control system for laser welding, stable performance and easy for beginner.

1. Processing speed is fast.
2. Small thermal deformation and heat affected zone (suitable for processing high melting point, high hardness, special materials)
3. Local heat treatment of the parts.
4. It can process complex shapes of parts and small parts, and can also process in vacuum.
5. No noise, no pollution to the environment.
6. Combine with computer technology to facilitate automation.
7. Improve the quality of the workpiece.
8. No pre-heat treatment is required, and the workpiece will not anneal after welding.
9. deformation-free collapse, no pores and trachoma.
10. can be used for cracks, collapses, corners, sand holes and repairs after use of the mold.


Fiber laser welder for mold repair can be used on titanium, nickel, tin, zinc, copper, aluminum, chromium, niobium, gold, silver and other metals and their alloys, as well as steel. Welding of the same material of such alloys as felling alloys may also be applied to copper-nickel, nickel-titanium, copper-titanium, brass-copper and other heterogeneous metal welding.

Mold industry
