Surfaces metal cleaning


This is a finishing procedure performed through sand launching so as to improve the surface appearance of metal pieces or parts of them. 

It can be executed with corundum and glass micro-balls: it is a manual and fine treatment such as to clean and polish the sandblasted pieces without the need of embedded abrasive particles; this procedure is generally used for fragile and valuable items. 

Among its most common uses are:

  • preparation of surfaces for subsequent treatments such as anodizing and chromium plating, ecc.;
  • removal of oxides and welding residuals;
  • polishing and opacification of moulds for plastic materials and pressure die-casting.
