Zinc Casting: A Flexible Technology for Making Precise Components
Of all the manufacturing processes that are implemented in a foundry, the zinc casting process is the most tried and tested process. Owing to its superb mechanical properties and the ease of casting, zinc has held its ground in being a material for making structures in diverse industries from automobiles to electronics and home appliances. The zinc casting process includes a number of advantages like low costs and high rate of production as well as the use of高度 precision complex geometries.

What is Zinc Casting?
Zinc Casting focuses on zinc alloys, in particular casting alloys zinc alloys, and casting techniques for manufacturing zinc alloy cast parts which do. It consists in that heated alloy, usually called zamak, is injected in concealed designs. One method of zinc casting is die casting, which is the most produced process. It is known as a process where molten zinc is injected in toward the die making it the shape of the casting that is desired. Such dies are manufactured to ensure rapid reproduction of identical, accurate components as many times as required. It is also possible to employ zinc casting by use of gravity casting but that is where molten zinc is poured into the cavity without pressure. Die casting however is the most common method used in mass production.
Zinc: Why is it Preferable to Use it in the Process of Casting?
Zinc possesses many properties that positively influence its use as a cast metal. Low melting temperature and very good fluidity as well as the possibility of making thin walled and highly detailed parts makes it suitable for die casting. On top of that, the strength, corrosion resistance and dimensional stability of zinc alloys make sure that the components produced are extremely durable. Below are the reasons why zinc is widely used in casting.
Low Melting Point
Zinc can readily be melted and casted due to its relatively low melting temperature which is approximately (419.5°C or 787.1°F ). It also has major advantage especially in mass production as it lowers the production cost. This is because less energy is required to liquefy the material as opposed to liquefying other metals like aluminum or steel.
High Precision
With zinc foundry there is no problem in making parts having tight tolerances as well as very intricate features that may be problematic to make on other metals. This is why zinc casting is useful in the making of high precision parts like gears, housings and sockets since accuracy of the components clover space is of advantage.
Corrosion Resistance
Zinc and other metals containing zinc are very resistant to corrosion and therefore they can be used in areas or sites which will be exposed to wet or aggressive conditions. The strength makes sure that should any zinc-cast fittings be required in the harsh engineering environments such as automotives the fittings will last long.
Superior Strength and Durability
Among other advantages, zinc alloys and especially those employed in casting possesses a high strength and impact resistance. Zinc casted components bear mechanical loads and frictional forces and are therefore useful in various functional components of machines, electronics, and so on.
Cost Efficiency
Because of low melting temperature of zinc and the capacity to be cast rapidly, the processes are very economical. Furthermore, the quality and consistency of the die casting moulds means that there is hardly any raw material wasting in mass production of parts.
The Zinc Die Casting Process
Melting the Zinc
The first step towards casting zinc is to melt the zinc or zinc alloy into a furnace. When this material turns into the required molten condition, it is ready for injection into the die.
Injecting the Molten Zinc
The liquidized zinc is then introduced into the prepared steel cavity (die) at a very high pressure. The pressure makes it possible for the liquidized zinc to occupy all voids and detail features in the die to make a perfect counterpart of the internal structure of the die.
Cooling and Solidification After the mold filling is completed, the zinc metal, because it has a lower melting temperature as compared to iron, solidifies within a very short time. As soon as the part is completely solidified, the die is removed from the machine and the part is taken out or ejected.
Trimming and Finishing After ejection, any material or flash that is protruding from the edges of the part would be removed by trimming or finishing processes. Depending on the looks and the requirement of the part, it is also subjected to various surface treatments that include polishing, coating and plating after manufacturing.
