Precision Mold Components Surface Treatment Function

Precision Mould Parts Surface Treatment Methods

The main surface treatment methods of die accessories are: electroplating, spraying, polishing, anodizing, blackening, etc.

The function is to improve the appearance, the corrosion resistance and wear resistance of the mold parts. Each has its own unique use environment and condition as below:

  • Steel Material Electroplating

Electroplating-Electroplating is a method of treating the surface of precision mold components with a layer of metal film. Different metals, such as chromium, zinc, or nickel, are used as coatings in different utility environments.

Usage: It is used for parts with low dimensional accuracy requirements. Because the thickness uniformity of electroplating is not easy to control, the accessary processing is required to ensure the accuracy when the dimensional accuracy is high.

  • Steel Material Spraying

Spraying refers to the treatment method of spraying a layer of coating on the surface of precision mold parts.

Usage: It can be used as the final surface treatment for parts requiring high dimensional precision and high wear resistance.

  • Steel Material Polishing

Polishing refers to treat the surface into a smooth, flat, burr free state.

Usage: To improve the appearance, the micro roughness and wear resistance of the mold and die parts.

  • Common Steel Blackening

Blackening refers to the method of treating the surface of the mold parts into a layer of black oxide film.

Usage: Ordinary steel as a kind of mold parts material, if it’s performance needs and corrosion resistance requirements are not high, blackening treatment can be cost saving.

  • Aluminum Anodizing

Anodizing- Anodizing refers to treat the surface of die parts into a layer of oxide film.

Usage: Because of its low hardness, usually used as an auxiliary mold accessories.

You may have surface treatment choice according to your needs. Below are some usual methods we use.
