Zinc Casting Metals

By Cherry / July 17th, 2024 

Zinc casting metal plays an important role in industrial manufacturing and is widely used in the fields of automobiles, electronics, electrical appliances and 

construction.

Its excellent physical and mechanical properties, as well as good casting process, make zinc casting metal the preferred material for manufacturing complex and high-

precision parts.

This article will discuss in detail the characteristics, processes, applications, advantages, and future development trends of zinc casting metal.

1. Characteristics of zinc casting metal

1.1 High strength and high hardness

Zinc alloys have high strength and hardness and can withstand greater mechanical stress and wear.

This makes zinc casting parts have good durability and stability during use and is widely used in high-load and high-frequency machinery and equipment.

1.2 Excellent casting performance

Zinc alloys have a low melting point and good fluidity, and can be cast at a lower temperature, reducing energy consumption and production costs.

At the same time, zinc alloys have a low shrinkage rate, can accurately replicate the shape and details of the mold, and are suitable for manufacturing high-

precision and complex parts.

1.3 Good corrosion resistance

Zinc alloys have good corrosion resistance and can maintain a long service life in humid and corrosive environments. This makes zinc casting parts more widely used in outdoor and harsh environments.

1.4 Easy to electroplating and surface treatment

Zinc alloys have excellent surface treatment properties and can be subjected to various electroplating, spraying, and coating treatments to improve the appearance 

and performance of parts.

This makes zinc casting metals advantageous in fields with high decorative and functional requirements.

2. Process of zinc casting metal

2.1 Hot chamber die casting

Hot chamber die casting is a commonly used zinc casting process for high-fluidity zinc alloys. In this process, the metal is melted in a heating chamber and enters 

the mold cavity through a gooseneck tube for rapid molding.

The hot chamber die-casting process is characterized by high efficiency, high precision, and strong adaptability.

2.2 Cold chamber die casting

Cold chamber die casting is suitable for zinc alloys with high melting points or that are corrosive to the heating chamber. In this process, the molten metal is 

heated in a separate furnace and then injected into a cooled mold cavity for molding. 

The cold chamber die-casting process is suitable for mass production and parts with complex shapes.

2.3 Gravity Casting

Gravity casting is a casting process that uses gravity to inject molten metal into the mold cavity.

This process is suitable for zinc castings with low cost, large size, and low precision requirements. 

The gravity casting process is simple and low-cost, but the production efficiency and precision are low.

2.4 Die Casting Mold

The die-casting mold is an important tool in the zinc casting process, which determines the shape, size, and surface quality of the casting.

The mold material is usually high-strength alloy steel, which is precision machined and heat treated to ensure its durability and stability.

The mold design needs to consider factors such as metal flow, cooling, and shrinkage to obtain high-quality castings.

III. Application of zinc-casting metal

3.1 Automobile industry

Zinc casting metal is widely used in the automotive industry to manufacture various parts, such as engine parts, gearbox housings, body structural parts and 

decorative parts.

Its high strength, wear resistance and good casting performance can meet the needs of automobile manufacturing for high-performance and complex-shaped parts.

3.2 Electronics and Electrical Appliances

Zinc-casting metal is widely used in the field of electronic and electrical appliances, such as motor housings, connectors, switches, and radiators.

Its excellent conductivity and heat dissipation can improve the performance and reliability of electronic products.

3.3 Building decoration

Zinc casting metal is used in the field of building decoration to manufacture door and window hardware, guardrails, handrails, and decorative parts.

Its good corrosion resistance and surface treatment performance can provide beautiful and durable building decoration products.

3.4 Industrial machinery

Zinc casting metal is used in the field of industrial machinery to manufacture parts such as gears, bearings, pump housings and valves. Its high strength and wear 

resistance can improve the working efficiency and service life of mechanical equipment.

4. Advantages of zinc casting metal

4.1 Cost advantage

The production cost of zinc casting metal is relatively low, mainly due to its low melting point, low casting temperature and low energy consumption.

Compared with other metals, the raw material cost of zinc alloy is also relatively low, which is suitable for mass production and low-cost manufacturing.

4.2 Production efficiency

The zinc casting process can achieve rapid prototyping and efficient production, especially the hot chamber die casting process, which can produce a large number 

of high-quality castings in a short time. High production efficiency can meet the market demand for fast delivery and large-scale production.

4.3 Design flexibility

Zinc casting metal has good fluidity and low shrinkage, can accurately replicate complex mold shapes and details, and provide high design freedom.

Designers can freely design parts of various shapes and structures according to their needs.

4.4 Environmental performance

Zinc casting metal has good environmental performance. Zinc is a recyclable metal material. Waste zinc castings can be recycled and reused in production, reducing 

resource waste and environmental pollution.

V. Future development trend of zinc casting metal

5.1 Application of new materials

In the future, zinc casting metal will continue to introduce new alloy materials to improve the performance and adaptability of castings. High-strength, high-wear-

resistant, and high-corrosion-resistant zinc alloy materials will further expand the application field of zinc casting metal.

5.2 Process improvement

With the advancement of science and technology, zinc casting technology will continue to improve and innovate.

New casting technologies such as semi-solid die casting, vacuum die casting and 3D printing will gradually be applied to zinc casting to improve the quality and 

production efficiency of castings.

5.3 Intelligent manufacturing

Intelligent manufacturing is an important direction for the development of zinc-casting metal in the future.

By introducing intelligent production equipment, automated control systems, and big data analysis technology, intelligent management and optimization of the 

production process can be achieved, and production efficiency and product quality can be improved.

5.4 Environmental protection and sustainable development

Environmental protection and sustainable development will become an important development trend of zinc casting metal.

By improving the recycling rate, and reducing energy consumption and pollution emissions, zinc-casting metal will be promoted to develop in the direction of green 

environmental protection and achieve sustainable utilization of resources.

Conclusion

Zinc casting metal occupies an important position in industrial manufacturing with its excellent physical and mechanical properties, good casting process, and 

broad application prospects.

In the future, with the continuous development of new materials, new processes, and intelligent manufacturing, zinc-casting metal will usher in a broader 

development space.

It is hoped that this article can provide valuable information for practitioners and readers, and promote the advancement of zinc-casting metal technology and the 

expansion of its application.
