From automotive to electronic communication, from household goods to medical devices, Haichen’s zinc alloy die casting technology provides efficient, economical and reliable solutions for modern industry.
How is zinc used in die casting?
Zinc alloy because of its low melting point, high fluidity, excellent mechanical properties and the advantages of surface treatment ability, can easily through the die casting process to produce products
Zinc alloy die casting process mainly includes the following steps:
(1) Mould preparation
Design and manufacture precision zinc alloy die casting mould, mould usually consists of two parts: moving mould and fixed mould. The mould needs to have high precision and durability to ensure the quality of parts.
(2) Zinc alloy melting
The zinc alloy material is heated to about 380℃ to make it completely melt into liquid state. Melting is usually carried out by the molten alloy method or pressure casting method.
(3) Injection moulding
The molten zinc alloy is injected into a pre-set mould cavity under high pressure. Injection speeds of up to 100 metres per second and extremely short filling times enable the moulding of high-precision and complex shaped parts.
(4) Cooling and Ejection
The zinc alloy is cooled and solidified in the mould, with the cooling time depending on the thickness of the part. After cooling, the finished part is ejected from the mould by an ejector mechanism.
(5) Trimming
The finished part is trimmed to remove excess material or defective parts. After trimming zinc alloy parts can be recycled.
Common Zinc Alloy Grades
Common zinc alloy grades include:
1.Zamak 3: Best overall performance, widely used in the automotive and electronics industries.
2.Zamak 5: Higher strength, but slightly less ductile for applications requiring higher hardness.
3.Zamak 7: Better flowability, suitable for thin-walled parts.
AZ series (e.g. AZ91D) : Good corrosion resistance and flowability, suitable for complex parts.
Haichen can select zinc alloy grades and optimise process parameters for your die casting production plan.
This can further improve product quality and production efficiency.
Benefits of using zinc die casting
Zinc Die Casting offers many significant advantages.
These advantages make it ideal for the manufacture of complex, precise and durable metal parts.
Below are the key benefits of zinc die-casting:
1. High strength and durability
Zinc alloys have excellent mechanical properties, including high strength, high tensile strength and high impact strength.
This allows zinc die castings to withstand high pressures and loads while maintaining their shape and integrity.
2. Cost Effectiveness
Zinc alloys have a low melting point, high productivity and long tool life.
Zinc die casting is therefore a cost-effective manufacturing method.
Compared to other metal alloys, zinc is less costly, especially in high volume production.
3. Dimensional accuracy and surface finish
Zinc die casting is capable of producing parts with very high dimensional accuracy and a smooth surface finish.
They can usually be used without further processing.
Dimensional tolerances can be ±0.025mm or less.
4. Design Flexibility
Zinc alloys allow for the manufacture of parts with complex geometries and thin walls while maintaining good dimensional stability.
This flexibility makes it suitable for a variety of industrial applications such as automotive, electronics and medical devices.
5. Corrosion resistance
Zinc alloys have excellent corrosion resistance, which makes them particularly suitable for use in application scenarios where they come into contact with corrosive substances.
6. High productivity
Zinc alloys flow well and cool quickly, allowing for faster mould filling and shorter production cycles.
In addition,hot chamber die casting moulds usually have a longer service life than aluminium or magnesium alloy moulds.
7. Versatile surface treatment
Zinc die castings can be enhanced in appearance and functionality through a variety of surface treatments such as plating, painting and powder coating.
For example, to improve corrosion resistance and aesthetics.
8. Environmental benefits
The zinc die casting process produces less waste and the zinc alloy can be recycled, which helps to reduce the environmental impact.
9. Wide range of applications
Zinc die castings are used in a wide range of industries, including automotive, aerospace, electronics, and medical devices.
Applications range from large structural components to small precision parts.
10. Reduced need for secondary processing
The high hardness and wear resistance of zinc alloys make them ideal for manufacturing bearings and other parts that require high wear resistance.
This reduces the need for secondary machining.
