Abstract

Compression molding is used to produce tensile bars to determine the strength of plastics. Due to inherent variability in measurements, several bars must be tested to establish mean values, and it is beneficial to produce multiple bars in a single molding cycle. But consistent bars will result only if each mold cavity experiences the same temperature-time history. Thus, an actual three-cavity aluminum mold has been modeled with finite elements, and the temperature distributions throughout its body have been predicted for a one-minute cycle and a 165°C molding temperature. Results demonstrate that all three polyester bars have nearly an identical heating history. The bars’ temperatures reach 177oC but quickly cool while the mold body remains near 165oC. This study was conducted by undergraduate students fulfilling their requirement to obtain the honor’s distinction for a heat transfer course.
