Repair instead of replace
- Repair worn or damaged injection molds, die-casting dies and stamping dies in place
- Low heat input keeps base-metal hardness — no post-heat treatment in most cases
- Fine, dense weld bead that polishes to a mirror finish
- On-machine repair without disassembly — less downtime
- Typical savings of 30–70% versus making a new mold
Common repair cases
- Corner damage and edge wear on injection molds
- Cracks and pitting on die-casting dies
- Worn guide surfaces on stamping dies
- Machining errors and venting-slot correction
Recommended BUVA machines
- Handheld Water-cooled Fiber Laser Welding Machine — precise pulse welding for mold steel
- 1200W All-in-One Air-Cooled Welder — workshop mobility for mold shops
- Portable Pulse Laser Cleaning Machine — clean mold surfaces before welding
FAQ
Does laser welding affect mold hardness? The heat-affected zone is minimal, so base hardness is largely preserved; pulse parameters are selectable per material.
Can repair be done without removing the mold? Yes — the handheld head reaches the damage point on the machine.
Which tool steels? H13, SKD11, P20, 718, S136, stainless and alloy steels.
