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.

Buyer Pain Points & Solutions

Thermal distortion on precision molds: TIG welding on polished mold cavities causes heat warpage that destroys dimensional accuracy. The fiber laser's concentrated beam deposits energy only at the weld point, keeping the HAZ under 0.2mm and preserving surrounding tolerances.

Post-weld grinding and polishing time: Arc welds leave raised beads requiring extensive grinding. The laser produces flush or near-flush welds with minimal reinforcement, reducing polishing time by 60-80% compared to TIG repair.

Repairing hardened tool steel: D2, H13, and S7 tool steels are prone to cracking with conventional welding. The laser's precise heat control and fast cooling rate minimize cracking risk on hardened tool steel repair.

Core Advantages

Microscope-guided precision welding - A 50x stereo microscope with crosshair reticle provides the operator a magnified view of the weld zone, enabling precise placement of weld material on cracks as fine as 0.1mm wide. The laser spot diameter is adjustable from 0.2mm to 2.0mm.

Adjustable pulse energy and duration - Pulse energy from 0.1J to 50J with pulse duration from 0.1ms to 20ms. This granularity allows welding of thin edges without burn-through and building up material on worn surfaces layer by layer.

Argon-shielded weld pool - Integrated argon shielding gas nozzle protects the weld pool from oxidation, producing bright, clean welds on tool steel, stainless steel, and aluminum alloy molds without post-weld discoloration.

Wire feeder for build-up welding - A precision wire feeder delivers 0.6-1.2mm filler wire for building up worn surfaces, repairing chipped edges, and restoring original dimensions. Wire feed speed is synchronized with pulse frequency.

Water-cooled laser source for continuous operation - The 2000W fiber laser source with water circulation cooling maintains stable output through 8+ hour repair shifts. The system stores 100+ weld parameter profiles for different tool steel grades and repair types.

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.
