Sandblasting & Cleaning Systems

Our sandblasting machines are designed to ensure efficiency, safety and high-quality results. As a manufacturer of industrial machinery, we guarantee durable designs, top-quality materials and comprehensive technical support. CORMAK’s range includes a wide selection of sandblasting and surface cleaning equipment, such as sandblasters – systems capable of meeting the needs of industry, workshops and renovation projects.

What is sandblasting – process and application

Sandblasting is a method of mechanical surface cleaning in which a stream of abrasive material – such as corundum, steel grit, glass beads or walnut shells – removes rust, old paint coatings, oxidised layers and other contaminants. This process produces a surface with a controlled roughness, ideally prepared for the application of new protective, paint or anti-corrosion coatings. Thanks to its effectiveness, sandblasting is widely used in restoration, in preparing components for painting, and in many industries where high-quality finishing is required.

What are sandblasting machines?

Sandblasting machines are devices that enable the sandblasting process to be carried out in a controlled, repeatable manner, tailored to the type of material being processed. It is thanks to them that it is possible to precisely direct the abrasive stream onto the surface of metal, steel, aluminium or structural components. A metal sandblasting machine allows you to quickly clean and prepare the surface for further processing, whilst a wheel sandblasting machine enables thorough preparation of the rims prior to refurbishment. These machines ensure stable operating parameters, high cleaning efficiency and full control over the final result, making them essential equipment in workshops, production plants and surface treatment companies.

Main types of sandblasting machines and equipment

Below we present the most important types of sandblasting machines and their characteristics:

• Cabinet sandblasters – fully enclosed chambers in which the operator performs sandblasting from the outside through gloves and a visor. The cabinets limit dust escape and ensure a safe working environment.
• Siphon sandblasters – operate by sucking in the abrasive using air and transporting it in an air stream. Their design allows for lower abrasive consumption and the use of various types of abrasive materials.
• Cabinet washers – used to clean components using a jet of medium (e.g. water or water-based abrasive) and chemical additives; ideal where sandblasting may be too aggressive or where drying and further processing are required.
• Equipment and accessories for sandblasting machines – essential for the proper operation of equipment used for sandblasting metals and other materials: guns, nozzles, extraction systems, gloves, viewing windows, filters, separators, and abrasive recirculation systems.

Equipment for sandblasting metals made of steel, aluminium or cast iron, whose surfaces are exposed to corrosion, oxidation, paint coatings and various types of contamination. For the cleaning process to be effective, the metal sandblasting machine must provide sufficient power, a stable flow of abrasive and full control over the intensity of the treatment. Only then is it possible to achieve a uniform, properly prepared surface that will meet the requirements of subsequent stages of production or renovation. Therefore, to be effective, a metal sandblasting machine must meet the following requirements:

1. Durability – a structure resistant to abrasion, overloads and vibrations,
2. Operator safety – sealed cabin, good lighting, visor with no blind spots, protective gloves, dust extraction and filtration,
3. Pressure adjustment and abrasive selection – different materials require different abrasives and jet intensities to avoid damage to the metal surface,
4. Ease of use and maintenance – quick replacement of consumable parts, access to accessories.

Applications of sandblasting equipment

Automotive industry

In the automotive industry, sandblasting is one of the fundamental methods of surface preparation prior to refurbishment or repair. It is used to clean steel and aluminium wheels, remove corrosion from vehicle frames, and restore engine components or bodywork. The method allows access to hard-to-reach areas where traditional abrasive tools fail. This makes it possible to thoroughly remove rust, old paint and contaminants, which significantly improves the adhesion of new paint coatings. In workshops specialising in classic car restoration, sandblasting is an essential step, as it allows the actual condition of the metal to be assessed and prevents further degradation.

Construction industry

In the construction industry, sandblasting plays a key role in preparing large steel components for painting, galvanising or further processing. Welded structures, trusses, pipes and load-bearing elements require a perfectly clean surface to ensure that anti-corrosion protection is durable. Sandblasting enables the rapid removal of scale, rust and residues from production processes, which translates into a longer service life for the entire structure. For large structures such as halls, bridges or industrial installations, specialised high-capacity equipment is used, allowing for continuous operation and treatment of large surfaces.

The aerospace and maritime industries

In the aerospace and marine sectors, surface preparation requirements are exceptionally high. Components of aircraft, ships or offshore platforms must be resistant to extreme environmental conditions, so the cleaning process must leave no imperfections. Sandblasting produces a uniform, appropriately rough surface that ensures ideal adhesion for protective coatings. In these industries, precision equipment with controlled jet force is often used to avoid damaging the material structure whilst achieving the highest quality of preparation. These are areas where sandblasting technology must combine effectiveness with absolute repeatability.

Crafts and restoration

In craft and restoration workshops, sandblasting is a tool that allows objects of great aesthetic or historical value to be brought back to life. It is used to restore antiques, metal furniture, decorative elements and architectural details. Thanks to the ability to select the appropriate abrasive and pressure, it is possible to work gently without damaging the material’s structure, whilst effectively removing old coatings and dirt. In arts and crafts, sandblasting is also sometimes used as a decorative technique, allowing for the creation of matt patterns on glass, metal or stone. This is an example of how industrial technology can become a creative tool.

Industrial production and metalworking

In facilities specialising in mass metal processing, sandblasting is a standard part of preparing components prior to powder coating, galvanisation or the application of protective coatings. Abrasive blasting ensures uniform surface roughness, removes scale from thermal cutting and improves coating adhesion. In the manufacture of machinery, equipment, structural components and precision parts, sandblasting is regarded as a stage that ensures repeatability and consistent surface quality, which has a direct impact on the durability of the finished product.
