Sand Blasting has a range of uses in a variety of industries.
For Jewellery it is commonly used as a surface finishing technique. The matt finish is deep, even and can be varied by changing the media. Castings can be cleaned up quickly and efficiently removing investment and evening the surface.
It is also increasingly useful in 3D prototyping where the surface often has print lines. Sand blasting evens the surface and gives a nice overall satin finish.
