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.
Features
-
Reduction of whiting/ghosting etc.
Improves the appearance on the parts by restraining slight scuffs so-called whiting, clouds or ghosting
-
Painted appearance
Gives plastics a painted appearance, and process of painting the parts might be skipped
-
Applicable without changing original grain structure
Only G Coat can be removed and re-coated
Other advantages
- Coating layer is extremely thin - 20 um or less
- Heating temperature is low and does not damage the steel
- Applicable either on running and existing tools
- There are few limitations on tool dimensions
Sample
-
Leather grain + G coat (molded with PP)
Without G coat. With G coat
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.
