Components used in the automotive, aerospace, consumer electronics, and hardware industries require high-precision thin wall metals. Zinc die casting is used to manufacture these parts because it has the capability of making complex parts with high accuracy.
As with all die casting methods, zinc die casting is a multistep process that combines the steps of melting, molding, and molding molten zinc alloy into the desired shape under high pressure.
Zinc die casting is quite popular because it is cost-effective and has high productivity, excellent accuracy, and remarkable part quality with superb surface finishes.
This article will explore the various uses of zinc die casting and why it is a preferred choice for many industries.

What is zinc die casting used for?
Zinc die casting is a versatile manufacturing process used across various industries for producing high – precision, lightweight, and durable components.
It is particularly popular in the automotive sector for creating intricate parts such as engine mounts, brake components, and transmission housings, where strength and weight reduction are crucial.
In the electronics industry, zinc die – cast parts are used for housings and enclosures due to their excellent dimensional stability and surface finish.
Zinc die casting is also widely used in the consumer goods sector for items like door handles, locks, and decorative fittings, thanks to its ability to produce complex geometries with tight tolerances.
Additionally, the aerospace industry benefits from zinc die – cast parts for their high strength – to – weight ratio and corrosion resistance, which are essential for aircraft components.

Haichen Zinc Die Casting – Medal Production
Precision Medal Manufacturing:
We have over ten years of experience in zinc alloy medal and commemorative coin casting.
For example, we have configured a 90-ton hot chamber die casting machine, using a 4-cavity mold to efficiently produce zinc alloy round medals with a diameter of 70 mm and a thickness of only 1.4 mm.
Haichen’s precision injection control and temperature management system ensures that every medal has a clear design and a bright surface, meeting the demanding requirements of high-end gifts and souvenirs.

High-End Automotive and Industrial Parts:
Our zinc die casting solutions also serve industries with stringent performance requirements.
Haichen ensures that its products meet 100% automotive safety standards through optimized mold design (using high-quality mold steel with a special cooling channel layout) and stable injection processes.
Engineering Support and Defect Prevention:
Haichen understands that the success of zinc die casting begins with excellent mold and process design.
We adopt advanced engineering methods, using mold flow analysis software for simulation during the mold development phase.
This can help predict the filling pattern of molten metal, optimize the gating system and venting, and effectively prevent potential defects such as porosity, cold shuts or incomplete filling before putting it into actual production, saving customers valuable trial molding time and costs.

Zinc die casting is extremely popular due to its versatility and reliability. It is used in the manufacturing industry because it can be relied upon to produce parts that need to be strong, precise and are needed in corrosive environments.
