Creating a texture surface on a material by using compressed air to blast abrasive particles against it.

Spray etching is a surface treatment process in which ink containing controlled particle sizes is sprayed onto a mold surface using a spray gun, following a specific texture or pattern requirement.

Photo etching is the process of using ultra-violet light to fix an image onto a sheet of metal, and then using chemicals to etch the shape into the metal, removing more and more of the material until only the shape is left.

Film etching is a surface texturing process where a photo film is precisely positioned and attached to the mold surface.

Group of techniques of applying texture processing on the surface of plastic moldings instead of engraving or pasting leather on the surface of a mold. One of the features is that original three-dimensional design patterns can be produced on the surface of finished products using processed data of design patterns. There is no need to make tangible design patterns.

Special coating technique originally developed by Tanazawa Hakkosha, which is to be applied on mainly grained surface of injection moulds. G COAT is applicable on any mould, as long as heat curing is applicable.
