Die Casting

about-pic

Die casting is a metal casting technique.

It involves injecting molten metal into a mold under high pressure, where it cools rapidly to form a workpiece with a specific shape. This method allows the production of metal parts with high precision and smooth surfaces.

Materials include

  • Aluminum alloys: Lightweight and highly corrosion-resistant, widely used in the automotive and electronics industries.
  • Zinc alloys: Good ductility and low melting point, suitable for complex structured parts.
  • Magnesium alloys: Lighter weight, commonly used in the aerospace and electronics industries.
Advantages:
  • High-efficiency production: Die casting allows for the rapid production of high-precision parts, making it ideal for large-scale manufacturing.
  • High precision and smooth surface finish: Die-cast products typically do not require additional processing and can directly form complex shapes.
  • High material utilization: There is minimal material waste, and most materials are recyclable.
Disadvantages
  • High initial cost: Mold production is expensive, making it suitable for large-scale production but not for small batches.
  • Limited material applicability: Not all metals are suitable for die casting, particularly high-melting-point metals.
  • Limited part thickness: Die casting is not ideal for producing very thick parts.
  • Porosity issues: Internal porosity may sometimes occur in die-cast parts, which can affect structural strength.

Applications
