Introduction to shot blasting

In the sheet metal processing machinery manufacturing industry, shot blasting is a key process that connects the processing links with the delivery of finished products. It is achieved by impacting the surface of sheet metal parts with high-speed projectiles (steel shots, cast iron shots, etc.) to achieve surface cleaning, performance optimization and quality improvement. Its necessity is mainly reflected in the following aspects:

1. Efficiently remove surface impurities to ensure quality in subsequent processes

2. Eliminate residual stress and improve dimensional stability

3. Enhance surface properties and extend part life

4. Optimize surface roughness and improve coating adhesion

5. Standardize batch processing to reduce production costs

Shot blasting is a comprehensive process in sheet metal processing that combines "surface purification + performance enhancement + cost optimization": it can not only eliminate surface defects left over from processing, clearing obstacles for subsequent processes; it can also improve product reliability through stress regulation and surface hardening. Moreover, its high efficiency and standardization are suitable for mass production needs. Especially in the fields of high-precision mechanical housings, load-bearing structural parts, and sheet metal parts for outdoor equipment, shot blasting is an essential link to ensure product quality and market competitiveness.
