Jewelry Sandblaster

What is it?

A jewelry sandblaster is a bench machine that directs compressed air and abrasive media through a nozzle to texture, matte, clean, or prepare metal surfaces. It is used on gold, silver, platinum, and stainless components to remove oxides, casting residues, or to create uniform satin finishes prior to plating or final polishing.

Characteristics

Typical features include a pressure regulator, moisture trap, media hopper, blast gun, viewing window, gloves, and a dust extraction port. Some versions add manometers, quick-change nozzles, and protective window films. A compact unit may include LED lighting and a small cyclone to manage airborne fines.

How to Choose the suitable one?

When selecting this type of equipment, consider:
Cabinet Volume: Ensure there is enough room for rings, pendants, and small batches without overcrowding.
Pressure Range & Control: Adjustable regulation helps tune the surface texture for different alloys.
Filtration & Dust Port: Compatibility with an external extractor helps maintain visibility inside the cabinet.
Ergonomics: Glove reach, viewing angle, and lighting influence handling comfort and accuracy.

Application Range

A jewellery sand blasting machine supports oxide removal after soldering, pre-plate surface preparation, satin finishing, and selective masking for pattern contrast. It is also applied to watch cases, clasps, and other small metal components. In mixed workflows, blasting may be followed by ultrasonic cleaning or tumbling to standardize surfaces before inspection.
