Unimog Parts Laser Cleaning Bay Area
Unimog parts are mixed steel pieces that pick up rust, grease, and old paint in threads, splines, and flat faces. Laser work can take that soil off so the part can be inspected and reused. The issues that matter are thread fit, heat on a thin bracket, and whether rust has already taken a spline or a bore. Keep the pass on the soil. A bright part that no longer fits is still scrap.

Cast Iron Laser Cleaning
Cast iron arrives under rust and foundry scale. After the pass those films are gone and the graphite stays in the metal, not blasted out of the face.
Iron Laser Cleaning
Iron arrives under rust and mill scale that hide the face. After the pass those films are gone and the metal is bare, not abrasive-blasted or pitted.
Tool Steel Laser Cleaning
Tool steel dies look filmed and oxidized before work starts. Afterward the operator has a still-hard working land without a blue temper stain.
Bronze Laser Cleaning
Bronze statues look green and crusty at the start. A stopped pass leaves the intended hue, not a raw wound where the crust once sat.
Hastelloy Laser Cleaning
Hastelloy welds look stained and dull before work. A stopped pass takes the stain off and the alloy still resists chemicals, not ground thin.
Mortar Laser Cleaning
Mortar joints arrive painted and weathered at the pointing. After the pass the laser leaves the pointing joint full, not raked out hollow.
Polypropylene Laser Cleaning
Polypropylene moldings arrive oily under mold release. After the pass the laser leaves the molded part shaped, not warped or browned.
Redwood Laser Cleaning
Redwood siding looks coated and weathered before work starts. Afterward the operator has bare boards that are still sound, without a char streak.
Stainless Steel 316 Laser Cleaning
Stainless 316 tube arrives under weld tint inside the bore. After the pass the laser leaves that bore smooth, not roughened or retinted.
Stainless Steel Laser Cleaning
Stainless steel looks straw-tinted and filmed before work starts. Afterward the operator has a bright chromium face without a burn track.
Aluminum Laser Cleaning
Aluminum starts dull under oxide that takes the first energy. After a stopped pass, that film is gone and the metal is not pitted.

Questions this footage answers
What does this Short show about cleaning Unimog parts?
The clip is a 34-second pulsed-fiber demo on Unimog drivetrain and frame steel. You see rust and old coatings leave while threads and fit faces stay readable for the next assembly step.
What energy range fits rust on Unimog carbon-steel parts?
Coupon near 1.42–4.26 J/cm² for rust on carbon steel, and keep stacked energy under about 5.7–15 J/cm² so bare metal does not mark before coating.
Can I copy these settings to every Unimog casting?
No. Treat the Short as path and soil-leaving proof. Re-check each grade and coating stack, especially on thin sections and threaded bosses, before you raise energy for production.
