| Abstract: | A design method of hot runner mold for PET bottle base was proposed to extend the temperature range of PET resin for better processing. The forming technology was analyzed, including drying of PET resin and the temperature control of mold work section. The construction of a hot runner mold and its mechanism were described. The results show that the design of the mold structure is reasonable. |
