Precision Mold Repair Fiber Laser Welding Machine
Mold and tool maintenance shops face a persistent challenge: repairing expensive injection molds, stamping dies, and precision tooling without causing thermal distortion or metallurgical damage to the surrounding material. Traditional TIG welding deposits too much heat, warping critical tolerances and requiring extensive post-weld machining. The Precision Mold Repair Fiber Laser Welding Machine from Shandong Xinhong CNC delivers controlled, low-heat-input laser welding specifically engineered for mold and die restoration - enabling micro-welding of cracks, edges, and worn surfaces with a heat-affected zone under 0.2mm.

FAQ
What tool steel grades can this machine repair?
The machine is suitable for repairing D2, H13, S7, A2, P20, and other common tool steels used in mold and die making. The adjustable pulse energy and duration allow optimization for each grade's metallurgical characteristics. Contact us with your specific tool steel grade for recommended weld parameters.
How thin can the weld be?
The minimum spot diameter is 0.2mm, allowing welding of cracks as fine as 0.1mm wide. Pulse energy can be reduced to 0.1J for welding extremely thin edges without burn-through. The microscope guidance system ensures precise placement at this scale.
Can the machine build up worn surfaces?
Yes. The precision wire feeder delivers 0.6-1.2mm filler wire synchronized with the laser pulse, building up worn surfaces layer by layer. This restores original dimensions on worn mold cavities and damaged die edges without excessive heat input.
What training is required for operators?
Basic mold repair laser welding can be learned in 2-3 days. The microscope-based operation is intuitive for operators familiar with precision work. We provide comprehensive training manuals, video tutorials, and remote support. Advanced techniques for complex repairs require additional practice.
Is the machine CE certified?
Yes. Xinhong's fiber laser welding machines are CE compliant for European industrial safety standards. Full compliance documentation is provided with every machine.
