Explore medium pressure die casting and its advantages over sand casting, offering precision and efficiency in manufacturing.

Medium pressure die casting is a manufacturing process where molten metal fills a metal mold at moderate pressure, typically ranging from 3 to 100 MPa (megapascals).

This method strikes a balance between the high pressure of High-Pressure Die Casting (HPDC) and the low pressure of Low-Pressure Die Casting (LPDC).

It is favored for producing complex parts with high precision and quality finishing, offering cost-effectiveness and durability.

Process of Medium Pressure Die Casting

  1. Mold Designing: A mold, usually made of steel, is designed according to the required geometry, incorporating cavities, cores, and intricate details.
  2. Mold Melting: Metal alloys such as zinc, aluminum, or magnesium are melted in a furnace until they reach the desired temperature and consistency.
  3. Molten Metal Injection: The molten metal is injected into a holding furnace and then into the mold at moderate pressure to ensure desired properties.
  4. Cooling and Solidification: The filled mold is allowed to cool down, ensuring proper solidification to prevent defects in the casting product.
  5. Ejection of Casting: Once the metal has solidified, the part is carefully ejected from the mold, ensuring the shape is fully formed.
  6. Finishing: Trimming and finishing steps are applied to remove excess material and ensure the product meets design requirements.
  7. Quality Control: Inspection is conducted to ensure overall product quality, surface finishing, and structural integrity.

Difference Between Medium Pressure Die Casting and Sand Casting

The primary difference lies in the process complexity and material selection:

AspectMedium Pressure Die CastingSand Casting
Process ComplexityAutomated and precision-oriented.Traditional and labor-intensive.
Material SelectionPrimarily uses non-ferrous metals like zinc, aluminum, and magnesium for high precision.Can utilize both ferrous and non-ferrous metals.
