Everything You Wanted To Know About The Shot Blasting Process

Have you ever checked the smooth surface of your vehicle? Do you believe that the metal parts came out of the mould in such a smooth fashion? Manufacturers of vehicles depend on the shot blasting process to smoothen the surface of the metal casing of the vehicle. Manufactured metal parts are not ready for use right out of the mould. Typically, they require welding work, powder coating, and a coat of paint. However, the surface of the metal has to be clean for these processes can happen. Shot blasting prepares the metal parts for additional processing such as powder coating and painting. This extremely vital process ensures the coat adheres properly to the metal. The process can clean away contaminants such as remove metal oxides such as mill scale or rust as well as clean off contaminants like oil or dirt. If you are in the metal processing industry, you need the help of a company offering a shot blasting service. In this process, the company offering the service use a special machine to shoot abrasive material at high pressure on the surface of the metal. Depending on the type of material used, a centrifugal wheel (wheel blasting) or a pressurised fluid (such as compressed air) may propel the shots.

Additional information about the process

The technological process mentioned above uses abrasive materials to remove different impurities from various surfaces. Owners of diverse industries that process metal use it as a prior-preparation of surfaces and for surface protection prior to further processing such as welding as well as colouring. The density, size, as well as the shape of the shots determine the results. The types of metal abrasives used in this process include aluminium pellets, copper shots, as well as steel grit. In other processes, the processing company uses materials such as crushed kernels, sodium bicarbonate, glass beads, as well as silica sand. The result of the surface being cleaned depends on several types of factors such as the impact angle of the particle, the velocity at which the abrasive is blasted on the surface of the metal, the coverage, and density of the strokes, the shape of the particle, as well as the mass of the abrasive particle. The vehicle industry apart, many other industries use this metal cleaning process such as shipbuilding, aviation, and metal manufacturing. The process is also used for the production of various types of chassis, pipelines, silos, and tanks.
