Advantages and Applications of Aluminum Pressure Die Casting

Introduction to Aluminum Pressure Die Casting

Aluminum pressure die casting is a process where molten aluminum alloy is injected into a steel mold cavity under high pressure, allowing it to solidify and form castings. This process is similar to "plastic injection molding", but the main distinguishing features of aluminium pressure casting are its high pressure and speed.

Classification of Aluminum Pressure Die Casting Products

Aluminum alloys can be classified based on their performance characteristics and uses into four types:

• Rust-resistant aluminum (LF)

  
  

• Hard aluminum (LY)

  
  

• Super hard aluminum (LC)

  
  

• Forged aluminum (LD)

Casting aluminum alloys are divided into four types according to the main alloying elements:

• Aluminum-silicon (Al-Si)

  
  

• Aluminum-copper (Al-Cu)

  
  

• Aluminum-magnesium (Al-Mg)

  
  

• Aluminum-zinc (Al-Zn)

Common grades include ADC12 (A383) and ADC10 (A380).

Advantages of Aluminum Pressure Die Casting

• Aluminium pressure die casting products offer excellent quality: the castings have high dimensional accuracy, smooth surface finishes, and high strength and hardness. The strength is typically 25-30% higher than sand casting, while elongation is reduced by about 70%. The aluminum pressure die castings also exhibit excellent dimensional stability and interchangeability. Thin-walled, complex aluminum castings can be produced, with the minimum wall thickness for zinc alloy pressure die casting reaching 0.3mm and aluminum pressure die casting reaching 0.5mm.

  
  

• High production efficiency: The machines have high throughput, enabling efficient manufacturing.

  
  

• Excellent economic benefits: Due to the precise dimensions and smooth surface of die-cast aluminum parts, minimal or no machining is required, or only a small amount of machining is needed. This improves metal utilization, reduces the need for processing equipment and labor hours, and lowers casting costs. Additionally, combining aluminum with other metals or non-metallic materials in the casting process saves both assembly time and raw materials.

Main Applications of Aluminum Pressure Die Casting

• Automotive Industry: Engine components, chassis, transmission systems, and radiators.

  
  

• Aerospace: Aircraft structural parts, engine components, and landing gear.

  
  

• Consumer Electronics: Smartphone, tablet, and laptop casings.

  
  

• Electrical Equipment: Electric motor housings, transformers, and switchgear parts.

  
  

• Telecommunications: Connectors and enclosures.

  
  

• Industrial Equipment: Hydraulic and pneumatic components, machine parts.

  
  

• Home Appliances: Cookware, small appliance housings, and vacuum cleaners.

  
  

• Medical Devices: Medical equipment housings and surgical tools.

  
  

• Marine Industry: Boat parts and propulsion systems.
