Zinc is a material used when parts require tight tolerances and thin wall thicknesses. The material’s high density and excellent mechanical properties make it particularly suited to high pressure die casting parts that require wear resistance and good durability.
In high pressure die casting of zinc, the material is melted and injected into a tool under high pressure. The flow properties of zinc make it possible to fill complex cavities quickly and evenly, minimising the risk of defects such as porosities.
Once the tool is filled, the material is stabilised under controlled pressure until it solidifies. The tool is then opened and the part is removed.
Zinc has a low melting point and high density, which means that parts solidify quickly and maintain high dimensional accuracy even with thin wall thicknesses. The material is well suited to castings with tight tolerances.
The choice of alloy, such as Zinc ZA5, affects the strength, wear resistance and corrosion resistance of the part.
By utilising zinc’s unique properties, it is possible to achieve several significant benefits in high pressure die cast parts.
Zinc’s fluidity makes it possible to cast parts with very precise dimensions, even in thinner sections. This reduces the need for post-processing.
The material’s mechanical properties ensure that the parts can withstand heavy loads and prolonged use.
Typical applications include, for example:
For parts that require a lower overall weight, magnesium high pressure die casting may be the right choice.
After high pressure die casting, your parts can be further machined to meet specific tolerances and functional and visual requirements. This may involve machining holes or fine-tuning surfaces.
With CNC machining after high pressure die casting, you get high-quality parts tailored to your requirements.
