  High pressure die casting (HPDC) is a fast and economical alloy technology by shooting the alloy melt into the metal mold under High pressure.

     高压压铸(HPDC)(High pressure die cast)通过高压压力将合金熔体射入金属模具而制造金属铸件,是一种快速而经济的合金铸造技术。

  HPDC can be used for aluminum alloy, magnesium alloy, zinc alloy casting, widely used in automobile, electrical appliances, electronic parts and household products molding. In the process of high pressure die casting, unreasonable melt filling can lead to the formation of porosity and shrinkage defects (ESCs) in the casting, which greatly reduces the mechanical properties of the casting.


  Using conventional die casting process to prepare castings, the solidification structure of the alloy is more uniform, and the remarkable degassing effect is formed. At the same time, this may lead to the introduction of new inclusions and encoils, which result in low elongation of the cast sample. Therefore, strict control of injection and mold filling process plays a decisive role in the quality of HPDC castings
