Shot blasting is a surface preparation technique that involves propelling small metal or ceramic beads, known as shot, at high speeds onto a surface. This process removes contaminants, rust, and old paint, making the surface clean and ready for further treatment, such as painting or coating. The equipment used in shot blasting includes a blasting machine and a dust collector to manage debris. Shot blasting is commonly used in industries like automotive, construction, and manufacturing to enhance the durability and appearance of metal components and structures.
