Mold Repair Capability
Localized Repair For Damaged Mold Areas
The laser welding head delivers concentrated energy to small repair areas, allowing operators to rebuild worn edges, fill cracks, repair cavities, and restore damaged machining sections without replacing the complete mold component.
Precision Repair On Complex Geometries
The microscope and CCD monitoring system provide direct visibility during welding, supporting repair work on narrow grooves, sharp corners, deep cavities, and fine mold details where positioning accuracy is critical.
Reduced Thermal Impact During Repair
The focused laser beam limits heat transfer around the welding area, reducing deformation, oxidation, and dimensional changes on precision molds requiring minimal post-processing.
Repair Applications
Injection Mold Repair
Used for repairing worn edges, cavity damage, cracks, gate areas, and ejector pin holes on plastic injection molds.
Die Casting Mold Restoration
Applied to aluminum, zinc, and magnesium alloy die casting molds requiring repair of erosion marks, thermal fatigue cracks, surface wear, and machining defects.
Stamping Die Maintenance
Used for restoring punching dies, trimming dies, forming dies, and progressive dies where replacement costs and production downtime need to be reduced.
Precision Tooling Repair
Suitable for molds and tooling components used in electronics, medical devices, automotive parts, connectors, and industrial components requiring accurate dimensional restoration.
Manufacturing Quality Control
Each machine completes inspection procedures from component verification to final welding performance testing.

FAQ
Q: What types of mold damage can this machine repair?
A: The machine repairs cracks, worn edges, cavity damage, machining marks, broken corners, and surface defects on injection molds, die casting molds, and stamping dies.
Q: What welding wire materials can be used?
A: The machine supports matching filler wires for mold steel, tool steel, stainless steel, aluminum alloy, and other repair materials.
Q: Does repaired mold surface require machining afterward?
A: Most repaired areas require only polishing or minor finishing because the laser welding process produces controlled weld layers with limited deformation.
Q: Can the machine be integrated into a production workshop?
A: Yes. The system supports fixture installation, customized worktables, and additional positioning solutions for production environments.
Q: What information is required before selecting a machine?
A: Customers should provide mold material, damaged area photos, repair position, mold dimensions, and expected repair process.
Q: Can welding samples be tested before purchase?
A: Yes. Customers can send mold samples or material pieces for welding evaluation and process verification.
Q: What documents are provided for export shipment?
A: Shipment documents include commercial invoice, packing list, user manual, electrical documents, and inspection records.
Q: What technical support is available after delivery?
A: Support includes installation guidance, operator training, process adjustment assistance, troubleshooting, and spare parts service.
