Sandcarving is the process of engraving using a stencil and a sandblasting machine. The sandblasting process propels an abrasive media such as Aluminium Oxide onto the surface causing abrasion and etching into the surface. The stencils protects the area not to be etched.
Stencils can be made of a variety of materials but we focus on SR3000 PhotoMask Film to create fine detail images through exposing SR3000 to artwork with ultra violet light and then washing out the image to create a very fine detail and sharp stencil/resist.
In the engraving industry sandcarving combined with photopolymer resist (SR3000) is used to engrave crystal and glass products such as trophies and glassware, metal plaques signage, timber and stone. You can engrave almost anything with the sandcarving process and it is often the best solution when you have an eneven surface or tricky positioning. Sandcarving provides a very fine detail indelible etching and it's versatility makes it a valuable process in any workshop.
Why Sandcarving
Sandcarving provides the most versatile engraving solution available and at very low cost compared to other engraving processes. You can engrave almost anything that is non-rubber and any shape.
Crystal and Glass
It provides a far superior result than any other glass engraving process available. You get very fine detail work and sharp crisp lines. It is by far superior to laser engraving methods which a) gives a duller finish with not as sharp line edges and b) does not like hi-led content crystal or cheap grade glass. With Sandcarving it does not matter about the quality of glass you get exceptional results on cheap glass right through to high quality lead crystal. It beats Laser Engraving in quality everytime.
Metal Etching
Sandcarving provides a superb solution to metal engraving needs. Whilst it does not produce depth but rather a surface etching that when paint filled looks fantastic and becomes permanent.
Sandcarve etching stainless steel is a very profitable process as it is much quick than traditional cutter engraving style. For example an A4 opening ceremony plaque which typical text and logo can be etched paint filled and cleaned up in just 40 minutes.
Timber Etching
Of course laser engravers can etch timber but they leave a streaky finish based on the variable density of the grain. With Sandcarving you get sharp edges and good depth which is then paint filled which makes it look like the best laser engraving you’ll ever see in timber as the paint (normally black) looks like a burnt laser finish but does not have the streaky look.
Stone Etching
Sandcarving does a magnificent job of stone etching. Granite, marble, rocks can all be etched easily with high definition detail.
Ceramic Etching
Glazed or unglazed ceramics can be easily sandcarved with intricate patterns. It is often used by artists to add sharp fine details into ceramic pieces. Crafts people etch into glazed coffess mugs for a creative and different effect.
