Abstract
Applications of a die-casting simulation program, dieCASÒ
, for design of a die-cast part is presented in this paper. dieCASÒ
software, originally developed at General Motors (GM) Research and
Development Center with die casting in mind, has proven to be a very
effective tool in evaluating the effects of different process parameters in
die-castings. Since its inception at GM in 1993, the program has been used
extensively in GM Powertrain and is now exclusively licensed and maintained
by Technalysis, Inc. Because it is designed to address the many unique
features of the die-casting processes, the obtained results are very useful
for die casters in making design decisions before the parts are made. The
results presented here demonstrate the power of the computer program dieCASÒ
in making process improvement decisions. With a case study conducted here,
it is shown that the ability to perform analyses fast allows several
iterations leading to superior results by fine-tuning of the process
conditions, cooling line locations and part and runner geometry in advance.
