How Does Dry Blasting Differ from Wet Blasting?

In this article, we will share with you the main differences between dry blasting and wet blasting and when and where they are used.

Dry blasting

Dry blasting as the name suggests does not use any fluid or water but uses compressed air to force abrasives like stainless steel round cut wire shot through a venturi nozzle.

The main benefits of dry blasting

1). it is cost-effective: One of the many advantages of the dry blasting process is that it is less expensive compared to wet blasting as you don’t need any extra machinery to either regulate the flow of the water or even remove the waste.

2). It is highly efficient: Dry blasting is a very efficient method of cleaning the surface of any metal of any earlier coating in a very short period.

3). It is highly versatile: As dry blasting requires very few hardware pieces and arrangements, you can easily use it in various places with a lot of flexibility. This allows you to use dry blasting in factories, building sites, and garages.

Wet blasting

Wet blasting also uses dry abrasives like aluminum cut wire shot but instead of compressed air, water is the medium that forces these abrasives through water injection nozzles, and Halo nozzles.

Main benefits of wet blasting

Wet blasting offers several advantages over dry blasting which includes the following.

1). Reducing dust: As the main medium that forces the dry abrasives like the AMS 2431 cut wire shot is water, it significantly reduces the dust that otherwise is generated in this process. This makes it very environmentally friendly.

2). Hydrostatic forces: As water is used in this process, it means that there is more mass at the point of impact which ensures that you will need a smaller amount of abrasives to clean the surface. Furthermore, thanks to the presence of water the noise produced in this process are also much less compared to dry blasting.

3). Cleaning: For certain surfaces, you don’t need a different washing cycle to clean the surface after the blasting process is completed. This single process can both clean the surface and also remove all the dust that is generated.

4). No static charges: Sometimes the static charges that are urged generated during the dry blasting process can cause blasts or fires if there are inflammable nearby. In wet blasting this risk is removed as the use of water in this process eliminates any chances of static charges.

Always Prefer Quality over Price When Selecting the Right Steel Shot

In many industries, steel abrasives, steel shots and steel grits are widely used to clean the surface of metal sheet, rubber, or any other material in a fast and cost-effective manner. Most of the time materials like copper cut wire shots , or aluminium cut wire shots are used for either cleaning or physical modification of a surface. At the same time conditioned carbon steel cut wire shots are used as a preparatory process for metal surface cleaning. In such metal surfaces scales, dirt, paint coatings or rust are cleared off. Additionally, the steel shots are also used for physically modifying the metal surface (like roughening it up) so that better application of paint and coating can take place on it. This shows how important steel shots are in many industrial processes. However, many manufacturing companies when trying to source steel shots from the market look for the cheapest option available. This is done to minimise the cost. However, this can have a big impact on the o...

The Main Difference Between Shot Peening and Shot Blasting.

If you are in the metal industry or the manufacturing sector, then you may have heard about shot blasting or shot peening. Both these processes are done to prepare metal sheets or workpieces for further processing. Let us understand what these processes are and the main differences between the two. What is the shot blasting process? Metal parts that are manufactured, are not utilised directly when they came out of the factory floor. They need powder coating, welding work, or a layer of paint before they are soldin the market. However, to do these, the surface of the metal part should be clean of any foreign element. In the shot blasting process, you can quickly remove foreign particles like oil, earth, metal oxides, plant scale to make the surface of the metal smooth. How does this process work? In this process, a high-pressure stream of abrasive media like stainless steel round cut wire shot , glass beads, copper shots, aluminium cut wire shots and other such media are thro...

The Usefulness of Glass Beads in Blasting Process.

You may have heard about the abrasive blasting method that uses VDFI 8001 cut wire shot and other such hard abrasives. However, you will be surprised to know that in many industrial applications where abrasive blasting is used, instead of using hard abrasives like the stainless steel shots , softer glass is being used. Glass beads offer a cost-effective and highly practical solution for those cleaning processes that need silica sand which is considered a health hazard. In this blog, we will like to explain the usefulness of glass beads in the blasting process. The perfect abrasive for softer surfaces The glass beads are mainly used as a cleaning agents wherein, the size of the bead ensures different outcomes. These beads are generally used on softer surfaces as they are not able to damage the surfaces on which they are projected at high speed (which a steel abrasive can). Environment friendly and cost-effective Glass beads are generally used in place of sand or silica becaus...
