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.
