Tooling Design & Manufacturing
Laser Welding
National Molding uses precision laser welding to repair, modify, and enhance molds with exceptional accuracy. This process enables fast tool adjustments without compromising steel integrity—helping maintain uptime and extend tool life.
Why Laser Welding Matters
Laser welding allows tooling teams to make highly targeted refinements without the heat distortion or downtime of traditional welding. Key advantages include:
- Precise, micro-scale repairs and feature adjustments
- Reduced lead time for engineering changes
- Lower heat input to protect mold structure
- Fewer full rebuilds and reduced maintenance cost
Micro-Precision Repairs
Restoring edges, corners, and fine features
Engineering Change Support
Quick turnaround for dimensional tweaks or design updates
Surface Restoration
Improving cosmetic areas or sealing vent locations
High-Hardness Steel Compatibility
Effective on tool steels, inserts, and wear surfaces
Supporting Production Stability
Laser welding helps maintain tool performance across:
- High-volume, long-running molds
- Multi-cavity tools requiring tight alignment
- Cosmetic or Class A parts
- Tools processing abrasive or reinforced resins
Laser welding keeps tools running longer—with less downtime.
