Assume you are injection molding plastics parts using a
polylactic acid. In the process, the resin is heated from room
temperature (25 oC) to 200 oC. The cycle time
is 5 second, and shot weight is 0.05 kg. Please calculate the heat
input per hour of the process. The heat capacity data of PLA can be
found from the excel file. The PLA used has 10, 000g/mol molecular
weight (weight-average), Tg around 59.35 oC
