Blasting Technologies

Blasting is a technology that propels abrasive media directly onto the surface of a workpiece at speeds of up to 170 m/s. The abrasive media is accelerated by airless turbines, compressed air, or electric pumps in water-jet cleaning applications. The blasting result depends on the type of blasting machine, the process parameters, and the selected abrasive media.

Rösler provides complete process solutions for surface preparation and finishing. Customers can choose from an almost unlimited range of vibratory finishing and blasting solutions. Through comprehensive testing, we consistently identify the most suitable and effective surface finishing solution for each customer’s requirements. This involves not only developing a specific process, but also selecting the correct equipment and consumables. We provide comprehensive, integrated solutions for all surface finishing requirements. Our success in the market confirms the effectiveness of this approach. The innovative developments and high quality standards that have made Rösler a global technology and market leader in vibratory finishing and blasting are no coincidence.

A blasting machine is a surface treatment system used to remove dirt, rust, paint, and other surface defects from materials. It is designed to eliminate contaminants from the surface by means of high-pressure air or water jets.

Blasting machines can be used to process a wide range of materials, including metal, wood, glass, stone, and plastic. They are widely used in industrial and commercial applications, particularly in sectors such as automotive manufacturing, shipbuilding, metalworking, and construction.

The operating principle of a blasting machine is based on removing foreign substances from a material surface by using high-pressure air or water jets. The process is performed with various abrasive media, such as sand, glass beads, aluminium oxide, or silica.

A blasting machine is used to clean, smooth, abrade, or prepare the surface of a workpiece. During the blasting process, a specially selected abrasive medium, usually sand, metallic particles, or glass beads, is propelled onto the workpiece surface under high pressure. The main applications and functions of blasting machines include:

• Surface Cleaning: Blasting is an effective method for removing dirt, rust, paint, varnish, and other contaminants from workpiece surfaces. It is especially common in the preparation of metal parts and the removal of old coatings.
• Surface Smoothing: Blasting can be used to smooth workpiece surfaces and eliminate unwanted surface defects or irregularities. This is particularly important before painting or coating, as a properly prepared surface improves coating quality and adhesion.
• Surface Preparation: Blasting prepares surfaces for painting, coating, or bonding. By removing dirt, oil, rust, and oxide layers, it helps create stronger and more reliable adhesion.
• Rust Prevention and Corrosion Control: Blasting can be used to remove rust and corrosion from metal surfaces, helping improve durability and corrosion resistance.
• Polishing: Blasting can also enhance the visual appearance of workpieces and create a more polished finish, particularly when specialised abrasive media such as glass beads are used.
• Surface Enhancement: In certain applications, blasting is used to improve the mechanical properties of a surface. For example, it may increase fatigue resistance or enhance surface hardness.

Depending on the type and size of the workpiece and the required process results, blasting can be carried out with different machine types and abrasive media. It is a widely used surface treatment method in industrial manufacturing, metalworking, shipbuilding, automotive production, construction-material manufacturing, and many other industrial sectors.
