What is Shot Blasting?
Shot blasting is a surface preparation technique where abrasive media, referred to as shot blasting grit or shot blast medium, is propelled at high velocity onto metal surfaces. This process removes rust, mill scale, and contaminants, creating a clean surface ready for coatings such as powder coating or hot zinc spray.
The key to effective shot blasting lies in the choice of abrasive, the blasting standards, and the precision of the equipment. A well-prepared surface ensures optimal adhesion and longevity for the subsequent coating.
Shot Blasting Standards: 2.5 Standard and 3 Standard
Standards in shot blasting are crucial for achieving the desired surface profile. The most commonly used standards are:
- 2.5 Standard: Also known as near white metal blasting, this level removes nearly all rust, mill scale, and coatings, leaving only slight stains. It’s ideal for most industrial applications.
- 3 Standard: Known as white metal blasting, this is the most thorough level of blasting, leaving the surface completely clean. It’s commonly used for critical coatings like hot zinc spray.
At NSP, we ensure all surfaces meet these rigorous standards to provide a flawless finish.
Shot Blasting Medium: Choosing the Right Abrasive
The choice of abrasive medium greatly affects the final surface. Some common options include:
- Steel Grit: Angular particles ideal for aggressive cleaning and profiling.
- Glass Beads: Spherical particles used for polishing and delicate surfaces.
- Aluminium Oxide: Durable and versatile for hard surfaces.
- Sand: Traditionally used but now less common due to health risks.
Each medium has specific applications. For heavy-duty jobs, shot blasting grit like steel grit is preferred, whereas glass beads are better suited for precision work.
Shot Blasting Equipment and Nozzles
The effectiveness of shot blasting depends heavily on the equipment used. High-quality systems, such as those supplied by Kube, offer advanced features like:
- Adjustable Shot Blasting Nozzles: Different nozzle sizes allow for customized blasting patterns, ideal for reaching intricate areas or handling large surfaces.
- Protective Roller Doors: These ensure safety and efficiency during operation.
- Air Extraction Units: These maintain a clean environment, reducing dust and debris.
- Shot Recovery Systems: Recycled abrasives lower costs and environmental impact.
Investing in advanced equipment guarantees consistency and quality across all shot blasting jobs.
Safety First: PPE for Shot Blasting
Safety is a top priority in shot blasting. The process generates high-speed particles and dust, which can pose significant risks. Personal Protective Equipment (PPE) is essential and includes:
- Air-Fed Helmets: Protects the operator’s head and respiratory system.
- Protective Overalls: Shields the body from flying abrasives.
- Heavy-Duty Gloves: Ensures hand safety during operations.
- Steel-Toe Boots: Guards feet against heavy objects and abrasives.
At NSP, we follow strict safety protocols to ensure the well-being of our team during every project.
