Sandblasting is a process involving the cleaning and smoothing of metal surfaces. A sandblaster forces solid sand particles across the metallic surface at high speed using a source of compressed air.
You get two types of sandblasting – “Siphon” and “Pressure” blasting systems and “Suction” blasting systems. You also get two types of sandblasting machines – portable blasters and fixed blasting cabinets.
What Are the Components of a Sandblasting System and How Does It Work?
Your sandblasting system consists of four components.
- Air source – The air compressor or bottled gas.
- Blasting cabinet – Houses the material you want to blast.
- Dust collection – Extracts dust from the blasting cabinet.
- Blasting media – The sand or material used for blasting the surface of your project.
Sandblasting is effective for removing old paint, rust, or residues from the surface of metal materials. The process is fast and effective, cleaning the surface of your project in seconds. The process can even remove marks, scratches, or other surface issues on your material.
The Steps for Successful Sandblasting
- When sandblasting technicians prepare and blast your project, they follow these steps.
- Open the cabinet door and hang the item on the hook inside the cabinet.
- Close the door and turn on the power to the blaster.
- Place your hands inside the heavy-duty gloves.
- Grip the blasting gun or suction hose.
- Step on the blaster foot pedal to start the process.
- Blast the surface evenly, avoid dwelling on any specific area.
- After blasting, blow off the project to remove any blasting media.
- Inspect the surface and repeat where necessary.
- Open the door and remove the project.
