Die-Casting is the injecting of a metal alloy into
a mold under a high pressure.
produces a consistent component with a good
surface finish and dimensional stability. There is
often no post-machining
process is cost effective)– but occasionally a
very light machining may be desired to
the required dimensional accuracy.
Die-casting applications include:
and other tools
Industry specific components (brackets, etc)
Tableware and kitchenware
Aluminum, zinc and copper
alloys make up the majority of materials used in
die-casting. A cold or hot chamber process can be
employed, depending on the fluidity of the alloy
you require. The cold chamber is particularly
useful for metals with higher melting points.
Whereas the hot chamber is used for metals with
low melting points and high fluidity.
From a designer's
perspective, it is best to design parts with
uniform wall thicknesses based on a core of simple
shapes. Heavy sections can result in cooling
problems, increasing tooling costs. Corners should
be radiused generously to avoid stress points.
