Shotblasting consists of the high-speed projection of an abrasive onto a surface to change its physical state or mechanical properties. This may entail cleaning or preparing surfaces to ensure that paint or other preparations to be applied will adhere perfectly to them, eliminating rust, corrosion and dirt or giving metal the desired roughness. Shotblasting is also widely used to harden a surface by creating surface tension. This is known as shot peening. The same process can be used to de-stress surfaces after machining or welding.
Different types of machine are used for different shotblasting processes, depending particularly on the type of workpieces to be treated and how they are loaded:
- Suspended load shotblasters
- Articulated table shotblasters
- Rotary table shotblasters
- Tunnel shotblasters
- Customised equipment
If a customer has a workpiece for which none of the above systems is exactly suited, we at MEBUSA can produce customised equipment tailored perfectly to the relevant process.
