what is vapor blasting?

Vapor Blasting usally called as water blasting,dustless blasting ,liquid blasting or wet blasting .

In short,Vapor blasting is a process which mix water and abrasives together to finish parts surface treating.

Compare with dry sandblasting, vapor blasting use less sand,less dust polution,and can get a perfect finish treating.

It can widely use on cast iron, aluminum, brass, mild steel etc 


After blasting it seals the parts surface, resulting in cosmetic enhancement and imparts a micro finish that helps
it resist further staining and oxidation.

Vapor blasting is a wet process. The water cushions the media (glass beads) impact,
provides a liquid honing effect and flushes away all of the contaminates (grease, dirt, oxidation, rust, etc.).
It flows and cleans in areas that dry blasting won’t, like inside of carbs, ports
and deep cylinder fins. The finish that vapor blasting provides is like the part was just cast.

The water component of the slurry provides a hydraulic cushioning effect to soften
the microbeads impact on the metal’s surface. Working together, they provide a gentle,
and somewhat time consuming process that peens the metal surface and leaves a bright lustrous satin finish. Finishes will vary from alloy to alloy and manufacturer to manufacturer, but all are good.
Aluminum castings in particular are well suited to this.

If you want get a perfect blasting treating,sometimes you have to try different mesh of sand,also time control.
