Sandblasting of metals for surface preparation and finishing
There metal sandblasting Sandblasting is a crucial step in industrial surface treatment cycles. This process removes impurities, oxidation, and residues from metal surfaces, preparing the products for subsequent processes such as powder coating, cataphoresis, or the application of protective coatings. Euroforesi, based in Luzzara in the province of Reggio Emilia, performs sandblasting on iron, steel, cast iron, and aluminum, ensuring precise and controlled processing.
Proper preparation of the metal substrate is crucial to ensuring optimal adhesion of subsequent treatments. For this reason, sandblasting is performed using specific equipment and with technical parameters calibrated based on the type of material and the size of the piece.
When sandblasting metals is done
There metal sandblasting It is generally performed before painting or surface protection treatments. The process involves projecting an abrasive grit, mixed with compressed air, at high speed onto the surface of the piece.
This process allows you to:
- eliminate rust, oxides and corrosive waste
- remove old paint or encrustations
- make the surface uniform
- improve the anchoring of subsequent coatings
Careful preparation helps reduce the risk of defects in the finishing stages, improving the overall duration of the treatment cycle.
How sandblasting is done
The process uses grit composed of inert materials and metallic abrasives, selected based on the characteristics of the substrate being treated. The size, shape, and hardness of the abrasive directly affect the intensity of the treatment.
The more resistant the metal surface, the larger the grit size used. Increasing the abrasive size has a more effective impact on the surface, allowing even deep alterations due to oxidation or atmospheric agents to be removed.
There metal sandblasting It gives the product a clean, uniform surface that is technically suitable for subsequent treatments, improving the overall quality of the final result.
Sandblasting systems
Euroforesi has two dedicated sandblasting systems, designed to handle components of various sizes.
Cluster system
Suitable for small and medium-sized parts. The components are positioned inside the machine and subjected to shot blasting by fixed turbines that treat all surfaces.
Maximum workable dimensions: approx.
2500 x 2800 x 1500 mm.
Pass-through system
System designed for large components. The turbines project the shot as the piece passes through the system.
Maximum workable dimensions: approx.
6000 x 2000 x 1000 mm.
This configuration allows us to offer a flexible sandblasting service, suitable for both serial production and large structural components.

Frequently Asked Questions
What is metal sandblasting?
It is a surface treatment that uses a jet of abrasive grit to remove impurities, oxidations and residues from metal surfaces.
Why is sandblasting important before painting?
Improves coating adhesion, reducing the risk of peeling or defects over time.
What materials can be sandblasted?
Iron, steel, cast iron and aluminium are among the commonly treated materials.
What sizes can be machined?
The systems allow the processing of components up to 6000 mm in length, depending on the type of system used.
Can sandblasting be integrated with other treatments?
Yes, it can precede cataphoresis, powder coating, liquid painting and anti-corrosion sealing.
