How Shot Blasting Is Used In The Auto Industry

In the auto industry, metal fabrication is a major process. After molding the necessary components, cutting, welding, and bending sheets of metals, all the components must be given a fine finish to ensure they are ready for the final coat of paint or powder coating. In many cases, shot blasting is normally used to smooth rough edges and get rid of imperfections on metal parts, such as the chassis of the vehicle, rims, valve trains, valves, camshaft, crankshaft, engine block, and other parts.  Different grades of shot blasting materials may be used on different parts to achieve the desired results. The velocity of the blasted materials can also be adjusted to achieve the desired finish. It is important to note that many shot blasting material suppliers ensure that manufacturers and fabricators have access to the highest quality blasting materials.

Shot Blasting Explained

This is the use of hardened spherical metallic materials to get rid of imperfections on a metal workpiece. The spherical materials are usually steel balls that come in a variety of sizes. The steel shots are usually hurled toward the targeted area at high speed. The impact of the high-velocity steel balls is known to harden the metal workpiece and does not lead to the formation of dust. The material used to make the spherical balls does not get impregnated onto the workpiece. It is important to note that these materials can be recycled, so shot blasting is an economical and environmentally-friendly option. That is why it is the preferred method for hardening metal workpieces in the auto industry. 

Types of Materials Used in Shot Blasting

i) Steel Shots

Steel is one of the hardest materials known to man. It has impressive rust resistance properties and strength compared to iron. Steel shots are the most common in the shot-blasting industry. They are durable, reusable, recyclable and do not produce any smoke when they come into contact with the workpiece. If you need steel shots, be sure to search for the best supplier in the industry. 

ii) Steel Grit

This shot-blasting material is produced by crushing steel shots, so they are not as smooth as steel shots. When abrasion is required on the workpiece, steel grit is usually the preferred blasting material. Workpieces containing stubborn oxides or rust can be renewed by blasting them with steel grit. The material is just as durable as steel shots and can be reused multiple times before it has to be recycled. 

iii) Aluminium Shots

When a smoother finish is desired, aluminium shots can be used. This is the preferred blasting material in the aeronautical and aerospace industries. Whatever your needs, be sure to look for the best suppliers of shot blasting materials. 

Since many suppliers exist in the shot blasting industry, you have to do some research to identify the right firm for your needs. Start by comparing experiences, reputation, quality of materials sold, and guarantees offered. This will go a long way in ensuring you get the highest quality shot blasting materials possible. You may also want to compare prices before you commit yourself.
