Sandblasting embeds media in the surface, chemical pickling creates a disposal problem, and both are slow to set up. Laser cleaning vaporizes rust, paint and oxide selectively, because the contaminant absorbs the beam far more readily than the substrate below it.
For production rust and paint removal, continuous-wave machines (1000–1500 W) are the workhorses: up to 15 m² per hour on heavy rust, from a wheeled cabinet that one operator can move anywhere in the shop.
For precision work — molds, dies, weld pre-treatment, heritage restoration — a 200 W pulsed source removes contamination layer by layer with virtually no heat transferred to the base metal.
Operating cost is where laser cleaning wins the spreadsheet: no grit, no chemicals, no consumables beyond electricity and an occasional protection lens. Payback against outsourced blasting typically lands between 12 and 24 months.
Every LaserForge cleaning machine ships with preset programs for common jobs, so results are repeatable across operators from day one.
