Therefore, precision control has become a key link in the sandblasting and rust removal process.

1. Adjustment of sandblasting pressure and nozzle size

Sandblasting pressure and nozzle size are key factors affecting rust removal effect and surface quality. By precisely controlling these two parameters, companies can adjust the strength and range of sandblasting according to the material and surface requirements of different workpieces to achieve the best rust removal effect.

• Sandblasting pressure: Excessive sandblasting pressure will cause excessive wear on the surface, while too low sandblasting pressure may not effectively remove rust. By fine-tuning the sandblasting pressure, you can ensure the rust removal effect while avoiding unnecessary damage to the surface.
• Nozzle size: The size of the nozzle determines the flow rate and coverage area of ​​the sandblasting. By choosing the right nozzle size, you can ensure that the sandblasting covers the workpiece surface evenly and accurately, avoiding uneven rust removal during the sandblasting process.

2. Selection of sandblasting materials

The selection of sandblasting materials is also crucial. Different sandblasting media have different hardness, particle size, and cleaning effects. Companies need to choose the most suitable sandblasting material according to the material and rust removal requirements of the workpiece. For example, for harder metal surfaces, choosing a blasting medium with higher hardness, such as aluminum oxide sand or steel shot, can ensure that rust is removed quickly and effectively; for metals with lower hardness, ceramic beads, and zirconium shots can be selected, and for more fragile materials, nylon sand, and resin sand can be selected.

3. The impact of precision control on surface quality

In the process of removing rust, precision control can ensure the smoothness of the surface and avoid excessive wear and surface damage. Precision control is particularly important in fields with high precision requirements (such as aviation, precision machinery, etc.). By finely adjusting each link in the sandblasting process, it can be ensured that the surface of the workpiece maintains both efficient rust removal and unnecessary wear, meeting high standards of surface quality requirements.
