High pressure zinc die casting is the process of forcing molten zinc based alloy under high pressure into a mould cavity. This delicate process can be influenced by a series of factors like the mould geometry, the composition of the alloy and the injection process that forces the molten metal into the mould.
In this Bruschi blog post, we'll dive into the most common defects that can appear in high pressure zinc die casting and a possible way to avoid them.
• Gas porosity
• Shrinkage porosity
• Possible solutions
Porosity influences the quality of final product in terms of tightness and strength. The most common porosity types are gas porosity, shrinkage porosity and leaks.
