Stacked Powder Coats Laser Stripped from Steel
Several heavy powder-coat layers on one part hide one film under the next, so they have to come off in turn. How the layers separate, leftover color in recesses, and heat that builds when the same spot is hit again decide when to stop.
What This Video Shows
Short mkAe0IbkG9Q shows pulsed laser clearing stacked heavy powder coat layers from steel in 47 seconds without grit.
Buyer questions about stacked powder coats
What does Short mkAe0IbkG9Q prove about stacked powder coat on steel?
The clip is a 47-second pulsed-fiber demo clearing multiple heavy powder coat layers from steel while the metal profile stays visible. It is footage proof that contactless strip can lift built-up industrial coating without a grit path, not a timed quote for every geometry or recoating history.
Why pick laser over blast when stripping stacked powder coats?
Thick stacked coats on steel often need to hold thickness for re-coat or weld prep. Media blast can erode the substrate and leaves grit to recover, while chemical baths add waste handling. The Short shows each layer leaving without touching the metal face.
How should teams transfer settings from this stacked-coat demo?
Read the Short for layer-by-layer clearing and the face going quiet, then coupon scrap with the same steel grade and coating stack before production overlap. Energy that worked on fewer layers can mark the next bracket if you skip that check ahead of coating removal work.
Where does published steel injury data cap stacked coating removal?
On coupon scrap, keep ns 1064 nm work below the carbon-steel injury band near 5.7–15 J/cm² while powder coat is still ablating. When the face stops giving off coating, stop the pass so leftover energy does not polish bare metal that still needs a new film.
