Die-casting Mould Tool Steel
Fushun are main manufacturer of tool steel for Die-casting Mould.
What is Die-casting Mould?
Die-casting moulds (for aluminum, copper alloys, etc.) are sophisticated tooling systems designed for producing metal components by injecting molten metal into precisely engineered cavities under high pressure. These moulds incorporate complex cooling channels, venting systems, and ejection mechanisms, along with carefully designed gates and runners to control metal flow. The mould assembly must maintain dimensional stability while repeatedly handling high-temperature molten metal and rapid cooling cycles.
The primary function of die-casting moulds is to produce high-precision components with excellent surface finish and dimensional accuracy. They are extensively used in automotive, electronics, and consumer goods industries to manufacture complex parts like engine components, housing units, and structural elements. This process offers advantages including high production rates, excellent detail reproduction, thin wall capabilities, and minimal post-processing requirements. Die-casting moulds can produce parts with complex geometries while maintaining tight tolerances and consistent quality.
The mould materials used in die-casting applications require specific alloying elements to withstand thermal fatigue and erosion from molten metal flow. Premium grade hot-work tool steels are used, containing carefully balanced combinations of chromium, tungsten, molybdenum, and vanadium to provide optimal thermal and mechanical properties. These materials offer excellent hot hardness, thermal shock resistance, and resistance to heat checking. The microstructure features thermally stable carbides that maintain hardness and wear resistance under repeated thermal cycling. Special surface treatments and coatings are often applied to enhance thermal fatigue resistance and prevent soldering of cast metal to the mould surface, while sophisticated heat treatment processes ensure optimal performance under extreme temperature conditions.
