| Surface treatment categories | Specific methods | Features | Advantages | Typical Applications | Special treatments |
|---|---|---|---|---|---|
| Surface hardening treatment | Nitriding treatment | Infiltrate nitrogen atoms into the mold surface to form a nitrided layer | Hardness can reach HV900-1200, small deformation, improve mold wear resistance | Suitable for molds with high friction coefficient materials | No subsequent quenching is required |
| Carburizing treatment | Carbon atoms are infiltrated into the surface of the low-carbon steel mold, forming a high-hardness layer after quenching, and the internal toughness is maintained | Strong wear resistance and impact resistance | Molds such as automobile bumper molds that need to withstand large impact loads | Heat treatment deformation is large, and subsequent finishing is required | |
| Quenching + tempering | Quickly cool the mold after heating, and temper at low temperature to eliminate stress | High surface hardness, improve the compression resistance of the mold | Suitable for small and medium-sized molds, such as electronic component injection molds, etc. | More precise control of process parameters is required | |
| Coating treatment | Hard chrome plating | Electroplating in a specific electroplating solution to deposit a layer of hard chrome on the surface | Improve the surface wear resistance of the mold, improve demoulding performance and corrosion resistance | Large molds such as home appliance housings | The chromium layer may become brittle |
| Nickel plating | Using chemical reduction reaction, a layer of nickel-phosphorus alloy is deposited on the mold surface | Improve the corrosion resistance of the mold and extend the service life of the mold | Plastic molds, rubber molds, etc. | It is a chemical reaction | |
| Surface finishing treatment | Mirror polishing | The mold is polished by sandpaper, abrasive paste, electrolysis, ultrasound and other means to achieve a mirror effect | The mold mirror polishing has a very high finish, and the roughness can usually reach Ra0.01-0.02μm, and there are basically no defects visible to the naked eye | Suitable for molds with high surface gloss requirements such as automotive parts, daily necessities, electronic products, and home appliance shells | It needs to go through multiple processes such as rough polishing, semi-finishing polishing and fine polishing, which requires higher experience and technology of engineers |
| Frosting | Through mechanical grinding, sandblasting or chemical corrosion, a tiny but uniform concave and convex structure is formed on the mold surface to change the light reflection effect of the mold | Make the mold surface matte and non-slip, and improve the aesthetics of the terminal product | Electronic equipment housing, household goods, cosmetic packaging, automotive parts and other molds to meet the design requirements | Can cover the surface defects such as welding marks and shrinkage generated during the production process | |
| Leather grain | Through chemical corrosion, laser engraving and other processes, specific textures and patterns are formed on the surface of the mold, giving the product better visual effects and touch | Improve the aesthetics and texture of the terminal product and meet functional needs | Automotive parts, electronic and home appliance molds, daily necessities and packaging molds, medical equipment molds, etc. | Various textures. Such as leather grain, metal texture, etc. |
