COSTAR Mould always keep the mind that a good quality preform mould start from the mould design. So good preform mould strucutre is most important. All of COSTAR Mould Co., Ltd engineers have been trained about the preform mould knowledge. We always keep the PET preform mould structure in our mind. Preform molds consists of the male core, the female cavity, and the neck inserts. The latter have to move during ejection of the part to release the undercuts created by the thread beads. For this purpose they are mounted on slides that are often cam-driven. Cores and cavities are always water cooled.
