Zinc die casting is a manufacturing process in which molten zinc alloys are injected under high pressure into precise molds to produce complex and accurate parts. This process is widely used in the modern manufacturing industry, especially in areas that require high strength and precision.
Zinc as the main material has excellent flow and shaping properties, which makes it particularly suitable for die casting. The low melting point of zinc alloys (around 427°C) helps to reduce the thermal load on molds and extend their service life. In addition, zinc alloys have good mechanical properties, including high strength and hardness, allowing them to withstand high dynamic and thermal loads.
A notable advantage of zinc die casting is the ability to produce parts with extremely thin wall thicknesses. For example, the wall thicknesses of certain electronic housings can be as thin as 0.5 millimetres, and as little as 0.2 millimetres in threaded areas. This high-precision production places high demands on mold design and casting technology.
However, there are also challenges in zinc die casting. Zinc alloys are sensitive to impurities such as tin, lead or cadmium, which can lead to intercrystalline corrosion. To avoid this, 0.02-0.05% magnesium is typically added to zinc die casting materials to increase corrosion resistance.
Overall, zinc die casting has established itself as an indispensable process in the modern manufacturing industry due to its efficient, precise and cost-effective properties and offers reliable component solutions for various industries.

Zinc die casting is a manufacturing process in which molten zinc alloy material is injected into a mold under high pressure and solidifies into precise components after cooling. Due to the low melting point of zinc (approx. 390 °C) and the narrow solidification interval, this process enables the production of parts with high precision and complex geometry, which are widely used in various industries.
In the electronics industry, zinc die casting is used to manufacture housings and connectors for electrical equipment, with the material's excellent conductivity and durability ensuring the performance and reliability of electronic devices. In the construction industry, door and window fittings such as handles and locks are widely used as they offer both robustness and aesthetic variety. In addition, model toys such as train and car models are often manufactured using zinc die casting to ensure fine detail and a high-quality appearance.
It is important to note that earlier zinc die-cast products occasionally exhibited the so-called "zinc plague" phenomenon, where intercrystalline corrosion led to volume increase and deformation. However, by closely controlling the alloy composition and ensuring high purity, this problem has been effectively eliminated.
