Die & Mould Laser Welding Machine
Repair worn moulds and dies precisely – without re-making them
Laser welding machine for die and mould repair. Builds up worn edges, cracks and engineering changes with filler wire — very small heat zone, no deformation and easy machining after welding.
- Laser type
- Pulsed YAG / fiber laser
- Laser power
- 200 W – 400 W
- Pulse energy
- Up to 100 J
- Spot size
- 0.2 – 2.0 mm
- Free sample testing
- Installation & training
- Pan-India service support
Re-making a damaged injection mould, die-casting die or press tool is expensive and time-consuming. The die & mould laser welding machine lets your toolroom repair it in hours. A fine laser beam melts a thin filler wire onto the worn area, layer by layer, building up material with almost no heat spreading into the tool.
Why toolrooms prefer laser repair
- No pre-heating and no risk of cracking hardened steels.
- Minimal distortion — critical dimensions stay intact.
- Dense, pore-free deposits that polish and texture well.
- Small weld beads mean less machining and polishing afterwards.
Models are available with a moving worktable, crane-style arm for large moulds and a stereo microscope for fine positioning.

Frequently Asked Questions
Can it weld hardened steel?
Yes. Because heat input is very low, hardened tool steels can be welded without pre-heating in most cases.
Is the repaired area machinable?
Yes. The deposit can be milled, ground, polished and textured like the original surface.
