Zamak 3 Zinc Die Casting Parts

Zamak 3 Basic properties of zinc die castings

 

Zamak 3, full name Zinc-Aluminum Alloy No. 3, is an alloy material composed of zinc (Zn), aluminum (Al), copper (Cu) and other trace elements. Among its main components, zinc accounts for the highest proportion, usually between 85% and 95%, while the addition of aluminum and copper significantly improves the hardness, strength and corrosion resistance of the alloy. Zamak 3 stands out among many metal materials for its good fluidity, easy processability, low cost and environmental protection.

 

Zamak 3 Zinc die casting production process: the essence of die casting technology

 

Die casting is one of the main processes for the production of Zamak 3 products. It combines the advantages of casting and pressure forming. It can inject molten metal into the mold under high temperature and high pressure, quickly cool and solidify to form the product of the desired shape. This process not only improves production efficiency, but also ensures product accuracy and surface quality.

 

1. Mold design: The mold is the core of the die-casting process, and its design directly determines the final shape and accuracy of the product. The mold design of Zamak 3 die-casting parts needs to consider factors such as the fluidity, shrinkage rate, and exhaust channels of the alloy to ensure that the product is defect-free during the molding process.

 

2. Melting and pouring: Put the raw materials with precise proportions into the furnace, heat them to a liquid state, and quickly pour them into the mold through a precisely controlled pouring system. Pouring temperature and speed are crucial to product quality. Too high or too low temperature will affect the fluidity and solidification effect of the alloy.

 

3. Cooling and demoulding: The molten metal in the mold is rapidly cooled and solidified under high pressure to form a solid casting. After the casting is completely cooled, it is ejected from the mold through the ejection mechanism for subsequent processing.

 

4. Post-processing: including steps such as deburring, grinding, polishing, electroplating or painting to improve the appearance quality and corrosion resistance of the product.

 

Zamak 3 zinc die castings have a wide range of applications

 

1. Automotive industry: Due to its lightweight and good processing performance, Zamak 3 is widely used in the manufacturing of automotive door locks, handles, steering components and other parts, helping to reduce vehicle body weight and improve fuel economy.

 

2. Hardware tools: In the field of hardware tools, Zamak 3's durability and cost-effectiveness make it an ideal material for making tool handles such as wrenches, pliers, screwdrivers, etc. Its comfortable grip and corrosion resistance can significantly improve the user experience.

 

3. Electronic product casing: With the development of technology, consumers have higher and higher requirements for the appearance and texture of electronic products. Through fine die-casting technology and diverse post-processing, Zamak 3 can produce beautiful and strong electronic product casings, such as mobile phone accessories, tablet computer casings, etc., meeting the market's demand for high-quality products.

 

4. Decorations and works of art: With its good casting performance and workability, Zamak 3 has also found its way into the field of decorations and works of art. Designers use this material to create a variety of artworks and home decorations with unique shapes and rich details, adding an artistic touch to people's living spaces.

 

Advantages: In addition to the above-mentioned lightweight, good processing performance, corrosion resistance and cost-effectiveness, Zamak 3 also has good electromagnetic shielding properties and is suitable for occasions where electronic components need to be protected from electromagnetic interference.
