SANDBLASTING
Surface preparation for effective nickel plating
Sandblasting is a surface pre-treatment service that we use to prepare metal components before electroless nickel plating or other technical coatings.
Through the use of selected abrasive materials, sandblasting makes it possible to remove impurities, oxides, scratches and imperfections, improving the morphology of the substrate and creating the ideal conditions for optimal coating adhesion.
A correctly prepared surface is the basis for uniform, resistant and durable nickel plating.
The advantages of sandblasting
Sandblasting and mechanical polishing techniques
At Deltar we use various surface preparation techniques, selected according to the material and the final application.
Sandblasting is carried out with abrasive materials such as corundum, Garnet and glass microspheres, able to remove from the surface any interfaces that would compromise the adhesion of the coating itself. It is also useful when a controlled and uniform roughness is required.
Rotorbital mechanical polishing, on the other hand, is carried out using flat or cylindrical brushes when a surface with a known and bright roughness is required, with high aesthetic quality of the finished component.
Both processes contribute to reducing surface defects and improving the overall quality of the treatment.
A tailored preparation for every application
The choice between sandblasting, polishing or a combination of the two techniques depends on several factors:
- material of the component
- geometry and required finish
- type of nickel plating planned
- functional and aesthetic requirements
Thanks to the experience gained in surface treatment, Deltar defines the most suitable preparation cycle for each application, ensuring reliable and repeatable results over time.
