All You Need To Know About Vapour Blasting And Cars

The two most common types of surface preparation techniques used in the auto industry are dry blasting and wet blasting. Dry blasting is also known as sandblasting. This is where abrasive media is propelled toward the target surface using pressurized air. When the abrasive media hits the surface, it dislodges rust, dirt, grease, and other types of impurities. The result is a cleaner surface that's ready for coating either by painting, electroplating, or anodizing. It is important to note, however, that sandblasting usually leaves some abrasive media impregnated on the surface, which may not be as smooth as desired.

Using a vapour blasting machine

Unlike dry blasting, which only uses air and abrasive media, vapour blasting uses a mixture of water, air, and abrasive media. This surface preparation technique usually provides a smoother finish for two key reasons. For starters, the water in the mix washes away any impurities, including the abrasive media. Secondly, the water in the mixture prevents abrasive media from getting impregnated on the surface.  It is important to note that vapour blasting is also known as wet blasting, slurry blasting, ductless blasting, or liquid honing. Vapour blasting is the preferred surface preparation method when a smoother finish is desired. 

A vapour blasting machine is normally used in a chamber to blast surfaces. The most commonly used abrasive media is glass beads. However, sodium bicarbonate can also be used. It is also possible to mix the two blasting media to achieve the best results. Pressurized water is used to propel the abrasive media toward the surface. After hitting the surface, the glass beads or sodium bicarbonate are cleaned and recycled. 

Common Uses of Vapour Blasting

Slurry blasting is the natural choice for cleaning old car and motorcycle parts. This helps to remove factory coatings, grease, rust, and other contaminants. Steel, chrome, and aluminium parts usually develop a satin-like finish after wet blasting. When you want to clean soft metal parts, dry blasting may not be the most suitable option. This is because the impact of the abrasive media on the metal will cause friction. The heat generated by the friction will lead to the bending of the soft piece of metal. In such cases, the most suitable option is to use vapour blasting. The water in the slurry will act as a coolant. In the engineering and aerospace industry, web blasting is normally used to remove paint, oxidation, carbon deposits, and other types of contaminants. 

Vapour blasting is common in the auto industry. Whenever you need vapour blasting services, you have to do some research to identify the best service provider. Only firms with state-of-the-art vapour blasting equipment, a lot of experience, and a wonderful reputation in the industry should be shortlisted. You'll also have to do some research on the fees charged by different firms to get information that may help you make an informed decision. This is necessary because you're looking for affordable vapour blasting services. That said, cost should be the last factor to take into consideration during your research.
