FAQs

Shot blasting is a surface preparation technique used to clean, strengthen, or polish a material's surface by forcefully propelling abrasive materials, known as "shot," at high speeds onto the surface. The impact of the shot removes contaminants, scales, rust, or old coatings, leaving behind a clean and textured surface.

Shot blasting involves the use of a shot blasting machine to propel abrasive materials, such as steel shot, grit, or sand, onto the surface of the material being treated. The abrasive particles impact the surface, removing impurities and creating a desired surface finish. The process is highly effective for preparing surfaces for painting, coating, or further treatment.

There are several types of shot blasting machines, including wheel blasting machines, air blasting machines, and wet blasting machines. Each type utilizes different mechanisms for propelling abrasive materials onto the surface being treated, catering to various applications and surface requirements.
