Join host Jonathan Filer in this episode of Alpha Welder as he showcases the AL-ROCK mobile laser system at Laser Hard, Inc. in Meadville, Pennsylvania. Discover how laser hardening offers a superior alternative to traditional induction hardening, eliminating part deformation and ensuring precise, localized hardening.
In this video, Jonathan and Dallas demonstrate a laser hardening application on a bottle mold used for producing one-gallon plastic milk jugs.
Why this matters?
- Parting lines (mating surfaces) wear significantly faster than the rest of the mold.
- Conventional heat treatment requires post-machining.
- Laser hardening eliminates post-processing and reduces turnaround time.
In this video, you’ll learn:
- Why parting lines are selectively hardened.
- How laser hardening increases wear resistance on critical mold areas (Stavax (420 ESR), ~30 HRC → low to mid 50s HRC).
- How repeatable and efficient processes are achieved with stored programs on the AL-ROCK system.
With real-time temperature monitoring and pre-programmed processes, laser hardening revolutionizes durability and efficiency for heat-sensitive components.
