Sandblasting (abrasive blasting) is the process of propelling an abrasive medium — steel shot or grit, corundum, glass beads — against a surface using compressed air or a turbine wheel. It removes rust, old paint, scale and contamination, and leaves a uniform surface profile ready for painting, coating or metallizing.
Sandblasting (abrasive blasting) is a surface treatment process that cleans and prepares metal parts by projecting an abrasive at high speed onto the surface. It removes rust, scale and old paint and creates a controlled roughness that improves paint and coating adhesion.
What is sandblasting?
Sandblasting is a technology for treating and finishing surfaces, in which an abrasive is accelerated — with compressed air or with centrifugal turbines — and projected onto the workpiece. In sectors such as metallurgy, shipbuilding or construction, it is an essential preparation step before painting or coating.
How does the sandblasting process work?
The principle is simple: a jet of abrasive, accelerated with compressed air or by turbines, hits the surface and mechanically removes contaminants while creating a defined roughness profile.
What types of sandblasting are there?
By medium: dry (abrasive only — fast and aggressive) and wet (abrasive with water — dust-free). By propulsion: automatic blasting with turbines (highest productivity, for large series) and manual blasting with compressed air (flexible, for specific zones and interior surfaces). By technique (in air blasting): injection type and pressure type.
What abrasives are used in sandblasting?
The choice of abrasive determines both the result and the cost. Common abrasives include steel grit (angular), steel shot (round), and ceramic or glass beads. A suitable abrasive means a better result and lower consumption.
Where is sandblasting used?
Sandblasting is present in many industries: metallurgy, automotive, shipbuilding, construction, foundries and more — wherever surfaces must be cleaned and prepared.
How to choose the right sandblasting equipment?
The correct selection depends on the type and size of the parts, the production volume, the material and the required finish.
