Zinc alloy die-casting parts are widely used in various fields due to their lightweight, high strength, conductivity, wear resistance, and excellent corrosion resistance.

1. Automotive Manufacturing  

Zinc alloy die-casting parts are extensively applied throughout automotive production. For example, they can replace traditional steel components in engines, transmission systems, wheel rims, support brackets, steering wheels, door handles, and seat accessories. This substitution significantly reduces vehicle weight and fuel consumption while improving safety and lifespan.  

2. Electronics and Electrical Appliances  

With excellent conductivity and dimensional stability, zinc alloy die-casting parts are used in manufacturing power adapters, laser printers, copiers, scanners, computer cases, peripheral device housings, connectors, plugs, as well as TV shells and audio equipment casings.  

3. Communications Industry  

Zinc alloy die-casting parts are widely utilized in the communications sector. For instance, shells and components for smartphones, tablets, and e-readers are often produced using zinc alloy die-casting. This process enhances product aesthetics while meeting lightweight, slim, and compact design requirements.  

4. Home Goods Industry  

In household products, zinc alloy die-casting parts are applied to items such as lamps, furniture accessories, and bathroom fittings. Despite their seemingly unrelated uses, these products rely on wear-resistant, corrosion-resistant, and high-strength zinc alloy components to ensure durability.  

5. Watches, Lamp Heads, and Locks  

Zinc alloy die-casting is also employed in producing watch cases, lamp heads, locks, and similar precision items.  

6. Construction Industry  

In architectural design, zinc alloy is commonly used for door handles, window frames, hooks, and other hardware components.  

7. Toys and Crafts  

Zinc alloy die-casting parts are used in manufacturing toys and decorative items such as car/airplane models, lighters, and keychains.  

1. Characteristics

The zinc alloy die-casting process features:  

(1) High surface precision and quality, with excellent hardness for wear resistance, corrosion resistance, and high-temperature tolerance.  

(2) High strength and pressure resistance, coupled with exceptional durability.  

(3) Aesthetic surfaces requiring no post-processing, enabling direct installation.  

2. Principles

This process involves injecting molten zinc alloy into molds under high pressure (typically >10 MPa) to form precise shapes. Pressure directly impacts product quality, with higher pressures yielding superior surface finish, accuracy, and wear resistance.  

3. Zinc Alloy Die-Casting Process Steps

Key stages include:  

(1) Mold Preparation: Heating and melting zinc alloy in a furnace.  

(2) Loading: Pouring molten alloy into molds.  

(3) Die-Casting: High-pressure injection to shape the alloy.  

(4) Tempering: Heat treatment to enhance surface smoothness and hardness.  

(5) Finishing: Removing parts from molds and polishing for aesthetics.  

4. Applications  

The process is widely adopted in automotive, electronics, and mold industries to produce components such as auto parts, electronic elements, and structural mold parts.  

5. Advantages of Zinc Alloy Die-Casting  

(1) High Yield: Smooth surfaces eliminate secondary processing.  

(2) Cost-Effective: Lower production costs compared to traditional methods.  

(3) Efficient: Rapid production speeds boost productivity.  

(4) Reliable Quality: Meets high-precision demands with superior consistency.
