Abrasive blasting

. Open abrasive blasting

Using 5–10 m³ of air per minute at 8 bar pressure, we accelerate abrasive particles—such as steel, sand, slag, or corundum with a diameter of 0.5 to 2.5 mm—to high velocity and blast them onto the surface through a nozzle with a diameter of 8–10 mm.

What few people know is that this nature-inspired technology was patented by Alfred Gutmann in 1893. This method of surface cleaning is now known as open-air or free jet abrasive blasting, and when quartz particles are used, it is commonly referred to as sandblasting.

These abrasive particles, with their immense impact energy, remove everything in their path—rust, mill scale, paint, tar, and more.
The process itself hasn’t changed in 120 years; only the technology has continuously evolved. When developing abrasive blasting machines and compressed air generation equipment, safety, health, and environmental protection are top priorities. A prime example of this is a screw compressor equipped with a helmet climate control system and a refrigerated air dryer.

Fémtiszta Kft. has been using this blasting technology for 32 years and will continue to do so in the coming decades, as abrasive blasting is the only method capable of ensuring the highest levels of cleanliness and surface roughness — essential for the long-term corrosion protection of steel surfaces.

Free jet sandblasting is particularly effective when cleaning workpieces with complex geometries or large surface areas, as the controllability of the blasting stream provides maximum flexibility. This technology can be used as a preparatory phase before surface coatings, but it is also suitable on its own for rust and scale removal. Thanks to decades of experience, our experts reliably select the appropriate abrasive type and blasting parameters for each individual workpiece, ensuring optimal surface quality for industrial, energy, and infrastructure projects alike.

FAQ

What is sandblasting? Sandblasting is a technology in which various abrasive materials are blasted onto a surface at high pressure to clean or roughen it.
What materials are used for sandblasting?
Our company primarily uses steel grit, corundum, glass beads, and sand. The material is always selected based on the surface properties and the desired result.
What surfaces can be treated with sandblasting?
Almost any metal surface can be effectively cleaned with sandblasting, including steel, aluminum, and other alloys, as well as concrete and wood surfaces.
When should sandblasting be used?
Sandblasting is applied to remove corrosion, rust, old paint, contaminants, and other deposits, as well as to prepare surfaces for further treatment, such as painting, galvanizing, or coating.
Is sandblasting an environmentally friendly process?
Yes, our sandblasting technology uses environmentally friendly, recyclable abrasives that minimize environmental impact.
How is the cost of sandblasting determined?
Pricing depends on the size, type, and condition of the surface to be treated, as well as the selected sandblasting method. For an exact quote, please contact us!
How long does the sandblasting process take?
The duration depends on the size and condition of the surface and the type of procedure. Sandblasting a small part can be completed within a few hours, while larger industrial components may take several days.
What happens after sandblasting?
After sandblasting, the surface is immediately ready for further treatments such as painting or coating, providing longer lifespan and more durable protection for the treated part or structure.
