I originally started using this for my aluminum motorcycle parts but when my boss saw a 3.2 intake he asked me to send out some pieces from the shop. We just got back two 67S sand cast aluminum cases. They aren't painted but they almost look that way. The vapor blast is a pressurized wet mixture of micro glass bead, water and soap. Done in a big tank. It polishes the metal vs leaving a rough finish like regular glass bead. It's also safe for internal engine areas. No residue. The guy I send the parts to is $60/hour and the exterior of the engine case took 2.5 hours. Intakes were 1 hour for the pair. My 40 year old motorcycle parts look like new. (Except for bigger scratches).

Parts look great....I don't like the name! Not a vapor process (IMG:style_emoticons/default/smile.gif)
Water+compressed air+glass bead ≠vapor (IMG:style_emoticons/default/headbang.gif) |

The first time I heard the phrase vapor blasting, I had something very different in mind until I started googling. It came out of the tank clean but ugly. (IMG:style_emoticons/default/sad.gif) I'm in the aerospace precision cleaning business and we never ultrasonic aluminum. What you see on the surface of the aluminum are cavitation marks generated by small implosions that are super hot in excess of 300F on the aluminum when the ultrasonics are on. Excessive exposure to sonication can generate pits and even cracks on the surface of the aluminum. When cleaning aluminum and ultrasonic cleaning is desired, its best to only do small burst 15-20 seconds of sonication at a time but not to exceed more that a few minutes in total for the cleaning.(IMG:style_emoticons/default/beerchug.gif) |
