Although shot blasting and sand blasting can both serve the purpose of cleaning and decontamination, shot blasting can strengthen the workpiece, but sand blasting is not so obvious. Sand and steel shot are used for grinding, derusting and surface treatment of castings; The shot is round, and the steel grit has edges and corners; the steel grit is broken by the steel shot, and the size of the steel grit is also divided into different models according to the size of the steel shot; for different castings, the product models used are also different. Depends on the piece; the hardness of the steel grit is moderate, with excellent resilience, and the casting is cleaned.
The best way to clean castings is to mix steel shot and steel grit, so that the steel grit can hit the corners and the steel shot can hit the flat surface, which also avoids the roughness of the casting surface. Mixed use will be much better than using a single shot blasting machine abrasive. However, this method is not suitable for every product. It depends on the workpiece and the final shot blasting effect.
