Description
Laser YAG Mold Laser Welding Machine Product Introduction
The YAG mold laser welding machine is a high-precision welding solution specially developed for the mold industry. It uses high-energy density pulsed laser to perform precise welding and repair on tiny areas of molds. Its core strengths include low heat input, small weld spots, and controllable welding depth. It is particularly effective for micro-cracks, edge chipping, blade reinforcement, and pit filling. Even with highly reflective materials like copper and aluminum or hard alloys like titanium alloy and tungsten carbide, this machine delivers excellent results, achieving post-weld hardness of HRC50+ without pores or cracks.
YAG Mold Laser Welding Machine Core Advantages
Ultra-fine welding spots ideal for microscopic repair areas
Extremely low heat input, heat-affected zone < 0.1mm with minimal thermal deformation
Excellent performance on copper, aluminum, and hard alloys with over 98% yield
Adjustable laser energy, frequency, and pulse width for precise control
Post-repair hardness up to HRC50+ with no pores or cracks
YAG Mold Laser Welding Machine Application Scenarios
1.During plastic injection molding, long-term exposure to high pressure and temperature can cause micro-cracks that affect product quality. YAG laser welding enables distortion-free micro-crack repair, ideal for mold cores and cavities.
2.Die-casting molds for aluminum or zinc alloys often suffer edge wear or chipping due to thermal erosion. YAG laser welding offers low-heat, precision repair to restore mold integrity and extend service life.
3.In multi-cavity molds, localized damage can be costly if full replacement is needed. YAG laser welding allows precise local repairs without disassembly, greatly reducing maintenance costs.
