Parameters used in the injection molding process, such as temperature, packing pressure, flow rate, etc. can be quantified. " Mold Constraint " is increasingly being seen as a major factor controlling shrinkage and warpage of an injected wax pattern. Is it possible to quantify Mold Constraint ? One possibility is that it can be specified as "relative mold constraint" when compared to a standard mold providing near zero constraint. Can anyone respond ?
