Shot blasting is a surface preparation technique that involves propelling abrasive materials, such as steel shots or grit, at a high velocity onto a target surface. This process is used to clean, roughen, or strengthen surfaces by removing contaminants, rust, or old coatings. Shot blasting machines are specialized equipment designed to facilitate this process. They consist of a chamber where the blasting occurs, an abrasive delivery system, and a dust collection system to ensure a clean and controlled environment. Shot blasting is commonly used in industries like manufacturing, construction, and automotive for surface treatment and preparation.
