Thanks to the great experience gained during these years STS can boast the ability to perform shine service within their production departments with staff with in-depth knowledge .

The polishing process performed by the STS of molds and components is a manual practice that involves the sequential use of abrasive systems ( stones , canvases , pastas ) adapted to reduce the surface roughness generated by the mechanical machining (tool for removal , grinding or EDM ) until obtaining optimal values ​​of Ra and ensure the best coating adhesion and promote a releasing effect .

Where the type of the application requires it , STS is able to prepare the surface with roughness typical of a lapping mirror .
