Chromium was discovered in 1797 by the chemist Louis-Nicolas Vauquelin. Sandblasting and shot blasting are used in the electroplating industry to prepare components before coating and, when required, for subsequent finishing operations. Sandblasting with angular abrasives, such as aluminium oxide, removes oxides, mill scale and surface residues while producing a defined surface roughness. The abrasive type, grit size and working pressure must be selected according to the material and the surface characteristics required before the electroplating process. Shot blasting with glass or ceramic beads, on the other hand, provides a less aggressive action and is mainly used to achieve a uniform surface with a consistent satin finish. It can be applied to components made of steel, stainless steel, aluminium, brass and other alloys. The process can be carried out using manual suction or pressure blasting machines or, for small parts suitable for batch processing, automatic rotary basket blasting machines. In the latter case, blasting time, blow-off time and basket rotation speed can be adjusted according to the component and the required process cycle. Process parameters therefore depend on the material, initial surface condition, abrasive type, grit size, working pressure and subsequent electroplating process. The same parameters should not be applied indiscriminately to different components and process cycles. In electroplating processes, surface preparation is essential to achieve a uniform coating and a high-quality finish. Industrial blasting machines remove oxides, residues and contaminants, preparing components for subsequent processing. Sandblasting and shot blasting are used on steel, stainless steel, aluminium, brass and other metals to achieve a uniform surface, obtain the required surface roughness or produce specific aesthetic finishes. Lampugnani offers robust and reliable manual sandblasting and shot blasting machines, with suction or pressure systems, suitable for surface preparation and finishing of components intended for electroplating processes. For small parts and repetitive production, automatic rotary basket blasting machines are available, allowing multiple components to be processed simultaneously. Dedicated timers allow the blasting and final blow-off cycles to be programmed, while the adjustable basket rotation speed makes it possible to adapt the process to different components. The correct selection of the machine, abrasive media and process parameters makes it possible to obtain clean, uniform surfaces ready for the subsequent electroplating process. Sandblasting removes oxides, residues and contaminants, preparing the surface for subsequent electroplating processes and helping to achieve a uniform and consistent finish. The selection of the abrasive media and grit size makes it possible to achieve different levels of surface roughness according to the subsequent coating process. Shot blasting with glass or ceramic beads produces a uniform surface and consistent aesthetic finishes on steel, stainless steel, aluminium, brass and other metals. For over 50 years, Lampugnani Sabbiatrici has been developing robust, reliable and easy-to-use machines designed for companies operating in the electroplating and surface treatment industries. The same sandblasting/shot blasting machine can be used for both sandblasting with abrasive media, such as aluminium oxide, and shot blasting with spherical media, such as glass or ceramic beads, adapting the process to different surface preparation and finishing requirements. Different machine configurations allow components made of steel, stainless steel, aluminium, brass and other alloys to be processed for cleaning, removal of oxides and residues, coating preparation and aesthetic finishing. Ease of use, simple maintenance and spare parts availability complete a range of solutions designed for everyday industrial use.
