Die casting is a metal casting process that involves forcing metal into a mold cavity under high pressure. This technique is often used to produce precisely defined metal parts with smooth or textured surfaces. The process typically uses non-ferrous metal alloys such as aluminum, zinc and copper.
Its advantages of high efficiency, speed and accuracy make it very suitable for mass manufacturing of metal parts with high precision and complex structure. Not only is it cost-effective to produce, lowering long-term costs by reducing wasted material and man-hours, it is also suitable for a wide range of metal materials to meet a wide range of applications. In addition, die-cast parts improve good surface quality and mechanical properties, providing an environmentally friendly and performance solution.
Die-casting technology is widely evaluated in many industries such as automobiles, electronics, aerospace, and medical equipment, and is mainly used for mass production of complex-shaped metal parts. This technology improves efficiency and accuracy and meets the needs of various industries for high-precision metal parts.

Cold chamber die casting and hot chamber die casting are two common die casting methods.
Cold Chamber Die Casting:
1. Processing method: In cold chamber die casting, the metal is usually melted in a furnace and then injected into the die casting machine’s mold chamber using a special device. The mold chamber is usually closed, and the metal solidifies and cools within it.
2. Advantages: Suitable for processing high melting point metals, high dimensional accuracy of parts, and good surface finish.
3. Disadvantages: Long production cycle and high cost.
Hot Chamber Die Casting:
1. Processing method: In hot chamber die casting, the metal is usually melted in a furnace and then injected into the die casting machine’s mold chamber using a special device. The mold chamber is usually open, and the metal solidifies and cools within it.
2. Advantages: High production efficiency, suitable for processing low melting point metals, and relatively lower cost.
3. Disadvantages: Part dimensional accuracy and surface finish may be slightly inferior to cold chamber die casting.
In terms of processing accuracy, cold chamber die casting usually achieves higher processing accuracy because of its faster cooling rate and less metal flow during solidification, which helps reduce shrinkage and porosity. Hot chamber die casting, on the other hand, may result in some shrinkage and porosity due to the better metal flow during solidification, leading to slightly lower processing accuracy in some cases.
Aluminum Die Casting
Aluminum Die Casting is commonly used in industries such as automotive manufacturing, aerospace, electronics, and telecommunications due to its favorable characteristics and diverse finishing options. The main materials used for aluminum die casting are aluminum alloys such as A360.0, A380.0, A383.0 (ADC12), A413.0 and so on.The advantages of aluminum die casting include its high strength-to-weight ratio, dimensional stability, recyclability, corrosion resistance, good stiffness, and high thermal and electrical conductivity.
Zinc Die Casting
Zinc is known for being easy to cast and is commonly used in hot chamber processes due to its exceptional casting fluidity and lower melting point. It has good strength and stiffness, allowing for the production of parts with thin walls and detailed features. Additionally, zinc alloys cool and solidify quickly, resulting in fast production rates. Zinc also offers a balance of mechanical and physical characteristics, including impact strength, high hardness, stability, and a high-quality surface finish that can be easily plated. China Casting Synergy Group offers popular types of Zamak and ZA die casting zinc alloys, such as Zamak 2 (ZA-2), Zamak 3 (ZA-3), Zamak 4 (ZA-4), Zamak 5 (ZA-5), Zamak 7 (ZA-7) and so on.
Magnesium Die Casting
Magnesium die casting is commonly used in industries such as automotive manufacturing, aerospace, electronics, and telecommunications due to its lightweight properties and structural strength. The main materials used for magnesium die casting are various magnesium alloys, including AZ91D, AM60B, AZ31B and so on. The advantages of magnesium die casting include its lightweight properties, excellent strength and stiffness, high dimensional stability, and good corrosion resistance. Additionally, magnesium die casting offers good thermal conductivity and electrical conductivity.
Surface treatment methods include sandblasting, shot blasting, powder coating, spray painting, anodizing, galvanizing, nickel plating, polishing and so on.
1. Sand Blasting:
Processing method: Sandblasting is the process of using high-pressure air to propel abrasive particles onto the surface of a workpiece to remove surface oxidation and dirt, while increasing surface roughness.
Advantages: Effectively removes surface dirt and oxidation, enhances coating adhesion, and increases surface roughness.
Disadvantages: May damage surface details, requires subsequent treatment.
2. Shot Blasting:
Processing method: Shot blasting involves using high-speed metal or abrasive particles to clean the surface, increase surface roughness, and enhance surface strength.
Advantages: Increases surface roughness and enhances surface strength, suitable for metal surface treatment.
Disadvantages: May damage the workpiece surface, material loss should be considered.
3. Powder Coating:
Processing method: Powder coating involves spraying molten plastic particles onto the workpiece surface to form a uniform plastic coating.
Advantages: Forms a uniform coating, providing excellent corrosion resistance and insulation properties.
Disadvantages: Subject to temperature limitations, not suitable for high-temperature environments.
4. Spray Painting:
Processing method: Spray painting involves spraying paint onto the workpiece surface to form a uniform coating.
Advantages: Provides a wide range of colors and decorative effects, suitable for various material surface treatments.
Disadvantages: Difficult to control coating thickness, consideration of solvent evaporation and environmental pollution issues is required.
5. Anodizing:
Processing method: Anodizing is the process of forming an oxide film on the metal surface to enhance corrosion resistance and surface hardness.
Advantages: Enhances corrosion resistance and surface hardness, with good decorative effects.
Disadvantages: Complex process, higher co
