A study on in-mold punching technology for hole piercing during molding of hollow plastic parts wasconducted. Considering the non-linearity of the HDPE plastic material, mechanical properties were obtained according tothe change in temperature and load speed. A standard specimen for the in-mold punching test was designed to implementthe in-mold punching process, and the specimen was obtained through injection molding. In order to analyze the influenceof process variables during in-mold punching, an in-mold punching mold capable of controlling variables such astemperature and support pressure of the specimen was designed and manufactured. Mold heating characteristics wereconfirmed through finite element analysis, and punching simulations for changes in process conditions were performed toanalyze punching characteristics and reflected in the experiment. Through simulations and experiments, it was found thatthe heating temperature, punch shape, punching speed, and pressure of the back side of the specimen were very importantduring in-mold punching of HDPE materials, and optimal conditions were acquired within a given range
