Mold Repair YAG Laser Welding Equipment Manufacturer

Product Description

Our Mold Repair YAG Laser Welding Machine is purpose-built for precision mold repair, leveraging high-energy YAG laser pulses to melt and deposit material exactly where needed. Using concentrated heat, the machine fills cracks, pores, and chipping defects with minimal thermal distortion—eliminating drawbacks of traditional argon arc welding and reducing rework. Ideal for repairing plastic injection, die-casting, stamping, and tooling molds across industries like electronics, auto, and medical.

Key Advantages

• Minimal Heat-Affected Zone: Reduces thermal stress and deformation on the mold

• Excellent Bond Strength: Ensures high-quality welds that match or exceed the base material’s hardness

• Versatile Metal Compatibility: Works with tool steels, stainless steel, copper, aluminum, titanium, and more

• Flexible Configuration: Adaptable laser head design allows repairs on complex geometries

• Durable Components: Long service life of laser cavity (8–10 years) and xenon lamps (8 million pulses)

• User-Friendly Control: Digital interface with adjustable welding parameters and memory presets

• Safe and Stable Operation: Built-in safety systems to protect operators and maintain consistent output
