When a new part or component of any machinery is designed using the die casting process, a lot of engineers of our clients do not pay attention to zinc. Because as they focus on the weight of the material to be used. Parts produced should be as light as possible, especially for automotive or small portable devices. In this case, the choice of aluminum or magnesium alloys is logical, whereas a zinc alloy can be more economical. If we look at the whole production process using zinc. Generally zinc die casting process has more advantages than disadvantages.
Properties of zinc
About the physical properties of zinc. Liquid zinc is the most fluid alloy. This means that it can be used to make the most complex and thin-walled cast parts. Thus, zinc alloy parts can be made as precise as possible, without subsequent machining. Unlike aluminum and magnesium die-cast parts. As a result, the cost of zinc products is lower.
The main costs of zinc die casting technology is the production of a mould. Since the melting point of zinc is lower than aluminium and magnesium, the service life of a mould for manufacturing zinc die casting parts can be 10 times longer. In order to manufacture zinc die casted parts the process of hot chamber die casting is used. Whereas cold chamber die casting is used for aluminium die casted parts.
