What is shot blasting

2024-08-23

Shot blasting, also known as sand blasting, polishing, rust removal, cleaning, etc., is a common surface treatment technology that uses high-speed ejected metal or non-metallic particles to impact the surface of an object to achieve rust removal, decontamination, increase surface roughness, improve surface quality, and other effects. A mechanical processing method.

Shot blasting is mainly used for surface treatment and cleaning of metal and non-metallic materials, such as automobiles, railway vehicles, mechanical equipment, bridges, buildings, pipelines, castings and other fields. It can not only effectively remove impurities such as rust, oxide layer, paint, cement, dust, etc., but also increase the surface roughness of the material, improve surface quality, improve coating adhesion, and extend the service life of the material.


Shot blasting is mainly divided into two types: compressed air shot blasting and mechanical shot blasting. Compressed air shot blasting uses compressed air to generate a high-speed jet flow to spray particles onto the surface of an object to complete cleaning, remove surface dirt, oxide layer, coating, etc.; mechanical shot blasting is to project particles onto the surface of an object through a mechanically driven shot blasting wheel to complete surface cleaning, increase surface roughness, and improve coating adhesion.
