Many manufactuning companies use molded parts as components of a process Shrinkage is often a major problem Thus, a molded die for a part is built larger nominal size to allow for part shrinkage. In an injection modeling study, it is known that the shrinkage is influenced by many factors among which are the injection velocity in it sec and mold temperature in degrees Celsius. The accompanying data sets show the results of a designed experiment in which injection velocity...
