Blasting techniques have evolved dramatically over the past few decades, with innovation leading to greater precision, efficiency, and safety. These methods are essential in various industries, from automotive and aerospace to construction and manufacturing. Among the most effective modern methods is surface blasting, a technique used to clean, polish, or prepare materials for further processing.
This article explores the different types of blasting technologies, their benefits, and the growing relevance of specific methods like vapour blasting in achieving high-quality results.
Understanding Surface Blasting Technologies
Surface blasting is a mechanical process used to remove surface contaminants, such as rust, paint, or scale, or to texture a surface for better coating adhesion. Traditional blasting techniques often use abrasive media propelled at high speeds using air or water pressure.
The most common types include:
- Sandblasting: Utilises sand or similar abrasive particles. It’s cost-effective but can be harsh on surfaces.
- Shot blasting: Involves steel beads or shots to clean or strengthen metal surfaces, commonly used in heavy-duty applications.
- Bead blasting: Uses glass beads to create a smooth finish, particularly on softer metals.
- Soda blasting: Applies sodium bicarbonate, offering a gentler clean ideal for delicate surfaces like chrome or soft metals.
