Abstract
A composite molding device is provided at the same site for preforming a closed-end parison or controlling the temperature of the closed-end parison as well as stretch blow molding the preform or temperature-controlled parison to a final product, such as a bottle. The composite molding device applied for stretch blow molding includes a clamping device, a pair of first mold halves, and a pair of second mold halves. The pair of second mold halves are removably placed between the pair of first mold halves in the clamping device so as to use the clamping device as a common clamping device.
