Hanger shot blasting machine is a type of surface cleaning equipment widely used in foundries, metal fabrication shops, and manufacturing industries. It is designed to remove rust, scale, sand, and paint from the surface of metal parts through the high-speed impact of steel shots.
In our production workshop, surface preparation is one of the most important steps before painting, coating, or further processing. Among many cleaning methods, the hanger shot blasting machine has become an essential piece of equipment due to its efficiency and versatility.
Top 5 Benefits Based On Real Operation Experience.
1. Excellent Cleaning Efficiency
The hanger shot blasting machine uses powerful high-speed impellers to throw steel shots at the workpieces. The blast stream covers all surfaces evenly, removing rust, scale, and old paint quickly. Even complex-shaped castings or welded parts can be cleaned thoroughly in one cycle, which greatly shortens the preparation time.
2. Suitable for a Wide Range of Workpieces
Unlike tumble or table-type machines, the hanger type can handle large, heavy, or irregularly shaped components. Parts can be hung individually or in batches on rotating hooks. This flexibility makes it ideal for automotive, foundry, construction machinery, and steel structure industries.
3. Damage-Free Cleaning
Because the workpieces are suspended and do not collide with each other during blasting, there’s minimal risk of surface deformation or damage. This is especially important for precision castings or welded structures that must maintain dimensional accuracy.
4. Reduced Labor and Maintenanc
The machine can be operated automatically with a PLC control system, reducing manual handling. The abrasive recycling system continuously separates dust and broken shots, ensuring consistent blasting performance and longer equipment life. Routine maintenance is easy—most wear parts can be replaced without complex disassembly.
5. Improved Surface Quality and Coating Adhesion
After blasting, the surface achieves a uniform roughness (Sa2.5–Sa3), which provides the perfect base for paint, powder coating, or plating. This not only improves the product’s appearance but also enhances corrosion resistance and coating adhesion, resulting in longer service life.
Conclusion
In daily production, the hanger shot blasting machine has proven to be a reliable and efficient tool for surface cleaning and preparation. Its combination of efficiency, versatility, and surface protection makes it one of the best choices for modern manufacturing workshops.
