In this episode of ALPHA WELDER, join Mike from Phoenix Laser Solutions as he showcases a high-precision repair on a plastic injection mold used to create trash can lids. Watch as Mike uses advanced laser welding techniques to fix an engraving error on the mold without needing to fully re-machine it—saving both time and cost.

Thanks to laser welding’s minimal heat input, Mike can work without preheating, maintaining material integrity and protecting nearby sensitive areas like timestamps. He finishes the repair by hand-benching the weld using a stone, ensuring a seamless and polished result ready for re-engraving. This efficient, non-invasive approach offers a practical solution for detailed mold repairs, especially in production environments.
