Introduction

Zinc alloy die casting is a technology widely used in

various types of industrial manufacturing.

It has attracted wide attention for its excellent performance

and economy.

In this article, we will explore the technical

characteristics and practical applications of zinc alloy

die casting in depth to help readers fully understand

this important manufacturing process.

Technical characteristics of zinc alloy die casting

High-precision and complex shapes

Zinc alloy die castings have high dimensional accuracy, 

complex shapes, thin walls, and smooth surfaces, and can

achieve bright light, spray paint, and baking effects

without secondary processing.

Zinc alloy die casting can produce parts with high precision

and complex shapes. Due to the high precision of the die casting

mold and the fluidity of the zinc alloy material, the

dimensional accuracy of the die casting product can

reach ±0.02mm.

This makes zinc alloy die casting particularly suitable

for the manufacture of parts requiring high precision, 

such as electronic equipment housings, automotive parts, etc.

Excellent surface finish

Zinc alloy die castings usually have a very smooth surface

with a surface roughness of up to Ra0.8μm. This means that

die castings can be used directly without subsequent

processing in many cases, greatly reducing production

costs and time.

High strength and good mechanical properties

Zinc alloy materials have excellent strength and toughness

and can withstand high stress and impact loads.

The tensile strength of zinc alloy is usually above 280MPa,

and the hardness can reach about HV120. Zinc alloy belongs

to non-ferrous metals with good plasticity and strength.

It can produce castings of various complex shapes without

defects such as cracking during the manufacturing process.

In addition, zinc alloy also has good fatigue resistance

and is suitable for manufacturing high-strength and 

high-durability parts.

Low melting point and energy consumption

Zinc alloy has a low melting point, usually between 380-420°C.

This makes the energy consumption of zinc alloy die casting

relatively low and the mold life is longer.

Compared with other metals, zinc has the advantage of small

heat storage capacity, good thermal conductivity, and good

liquid flow performance.

In addition, the die-casting equipment has a high degree of

automation and high production efficiency.

In addition, the low melting point also means that zinc alloy

can be easily composited with other materials, such as the

molding of inlays.

Green and environmental protection

Zinc alloy has a high recycling rate, no harmful waste gas and

wastewater is generated during the production process, and

zinc itself is a harmless metal to the body, which can

well protect the environment and human health.

Application of zinc alloy die casting

1. Electronic products

Zinc alloy die casting has been widely used in electronic products.

Due to its good conductivity and shielding properties, zinc alloy

die castings are often used to manufacture various electronic

products such as shells, frames, sockets, and internal

structural parts, such as mobile phone shells, computer

shells, audio shells, etc. Zinc alloy has the characteristics

of high strength, conductivity, and easy processing, which

is suitable for the production of electronic products.

In addition, zinc alloy also has good heat dissipation

performance, which helps to improve the reliability and life of electronic products.

2. Automotive industry

Zinc alloy has high strength and corrosion resistance.

In the automotive industry, zinc alloy die casting technology

can manufacture various types of automotive parts, such as

engine brackets, engine fans, oil pump housings, transmission

housings, door handles, and other parts of engine parts.

These parts need to have high strength, wear resistance,

corrosion resistance and other characteristics.

The high strength and corrosion resistance of zinc alloy enables

these parts to maintain good performance in long-term use.

In addition, the high-precision characteristics of zinc

alloy die-castings help improve the assembly accuracy

and operating stability of automotive parts.

3. Household appliances

Zinc alloys have the characteristics of high strength, 

conductivity, and heat resistance, and are suitable for long-term

use of household appliances. Zinc alloy die-castings are also

widely used in household appliances. Zinc alloy die-casting

technology can manufacture the shells, control panels,

top covers and other parts of various household appliances,

such as washing machines, water heaters, refrigerators,

microwave ovens and other equipment. The high strength and

good mechanical properties of zinc alloy materials enable

these parts to withstand large loads in long-term use.

In addition, the excellent surface finish of zinc alloy

die-castings also help to improve the appearance quality

and market competitiveness of household appliances.

4. Architectural Hardware

Zinc alloy die-casting technology can manufacture various

architectural decoration products, such as door handles,

handles, aluminum window hardware, etc. Zinc alloy products

have the characteristics of high strength, toughness, and 

corrosion resistance, and are also suitable for outdoor use.

In the field of architectural hardware, the high-strength

and corrosion resistance of zinc alloy materials enable

these hardware to maintain good performance and appearance

in long-term use. In addition, the zinc alloy die-casting

process can produce high-precision and complex-shaped parts,

which helps to improve the functionality and decorativeness

of building hardware products.

Conclusion

In short, zinc alloy die-casting technology has a variety of

application fields. With the continuous advancement of science

and technology and the continuous updating of production

equipment, zinc alloy die-casting has become an important process

in modern industrial manufacturing with its unique technical

characteristics and wide application fields.

By understanding the high precision, excellent surface finish,

high strength, low energy consumption, and other characteristics

of zinc alloy die-casting, we can better use this technology

to produce a variety of high-quality parts.

Whether in the field of electronic products, the automotive industry,

household appliances or building hardware, zinc alloy die-casting

has shown its unique advantages and broad application prospects.

Through the introduction of this article, I hope that readers can 

have a comprehensive and in-depth understanding of zinc alloy

die-casting technology, and make better use of this technology

in practical applications to improve product quality and production

efficiency. If you have any questions or needs about zinc alloy
