Shot Blasting Machine Wiki

Shot blasting is a process that treats metals to remove rust, grease, scale, and other irregularities to create a smooth surface for applying a finishing surface. During this process, ssome abrasive material is blasted onto the surface and depending on the surface being treated, they may be sand, beads or water. It is important to create a smooth and clean surface to apply the final surface treatment, like, powder coating, to the metal surface to achieve a high-quality, beautiful and durable surface treatment. Shot blasting machine is a mechanical method that uses centrifugal wheels to propelling the abrasive to remove surface and other impurities from the surface of steel applications. In general, blasting prior to finishing serves three primary purposes:

· Cleans and descales surfaces

· Increase texture to enhance paint adhesion

· Properly reduces maintenance costs by extending coating life

Benjamin Tilghman was a general in the army and saw the effect of wind-blown sand on windows in the desert. This might be the basis of his shot blasting machine invention.[6];

On October 18, 1870, Tilghman filed a patent, titled “Improvement in cutting and engraving stone, metal, glass, etc.”, in the US (US patent 108,408.), [7] detailing many unique applications of the technology, such as sharpening files, carving bottles, cleaning boilers or turning The wood grain comes out. Later that year, a patent was issued in the UK.

Broadly, there are two methods of shot blasting machines: air blasting and mechanical blasting (also known as airless blasting, and wheel blasting).[8]

According to different structures of casting metal parts, shot blasting machine can be divided into roller conveyor type, hanger type, rotary table type, tunnel type, barrel type, trolley type, and so forth.[9] [10]

Initially, the shot blasting machine was used for industrial purposes, such as removing rust or polishing metal before painting. Nowadays, the technique has decorative purposes, including sculpting and texturing. Current uses include engraving awards, such as trophies and crystal awards, production of 3D signage, glass decoration, and building refurbishment, however one of the earliest items to be sold after was Alfred Dunhill's pipes which he found sold for more money than his smooth pipes.

Nowadays, the shot blasting machine has become a mandatory industry for every industry, mainly including automotive, construction,  wind power railway Industry, foundry-forging, and shipyard industry, to clean and polish surface metal preparation. The main benefit of the shot blasting machine is that it provides an effective and smooth surface to any kind of the metals.[11]
