Mold and Die Laser Cleaning Applications

Laser cleaning in mold and die applications removes carbon buildup, release agents, epoxy residue, and rubber deposits from injection molds, die-cast tooling, and stamping dies without disassembly or abrasive damage to polished cavity surfaces. Nanosecond-pulsed fiber lasers ablate mold release and charred polymers from deep cavity features and thin ribs where mechanical cleaning causes dimensional loss. Tool steel and P20 chrome-plated molds are primary substrates, and surface finishes as fine as SPI A-1 are preserved at optimized fluence levels. In-situ cleaning cycles integrated into press downtime reduce tooling change intervals measurably. Debates persist on whether CW or pulsed modes better handle adhesive rubber flash on tire and gasket dies.
