Die-Casting is produced by injecting a metal into
a mold under a
high pressure between 1,450 and
30,500psi. Die-casting can produce, in a
consistent part, good surface finish and
dimensional stability. For many parts, there is no
post-machining needed or very light machining may
be asked for to bring dimensional accuracy.
Die-Casting can be done by using a cold chamber or
hot chamber process. It depends on the different
molten metals to be ladled. The cold chamber is
particularly useful for metals with higher melting
points. The hot chamber is used for metals with
low melting points and high fluidity.
Aluminum, zinc and copper alloys make up the
majority of materials which are used in
die-casting. From a design point of view, it is
best to design parts with uniform wall thicknesses
and cores of simple shapes. Heavy sections can
cause cooling problems and also produce high
tooling cost investment. All corners should be
radiused generously to avoid stress concentration.
Draft allowance should be provided to all for
releasing the parts, these are typically 0.25º to
0.75º per side depending on the material.
