Mold is the key to zinc alloy die casting. The design of the mold directly affects the shape, accuracy and surface quality of the finished product.
The mold should take into account the complexity of the product, wall thickness, cooling method and other factors to ensure that the final product meets the customer’s requirements.
Melting And Injection:
The zinc alloy is melted at high temperatures and the molten metal is injected into a pre-made mold through a die casting machine.
The injection process requires high pressure to ensure that the zinc alloy fully fills every detail of the mold.
Cooling And Curing:
Once the zinc alloy has filled the mold, the cooling process begins. During the cooling process, the zinc alloy gradually solidifies into shape.
Demolding And Spraying Of Release Agent:
After cooling, the finished product needs to be removed from the mold, a step known as demolding.
The mold is then sprayed with a release agent, which is a substance applied to the surface of the mold to reduce or prevent adhesion between the molten zinc alloy and the surface of the mold so that the finished product can be more easily removed from the mold.
Release agents help to ensure the smooth running of the process, while improving the surface quality of the product and protecting the life of the mold.
