PET preform mould plastic injection molding

If the mold temperature is low and uniform, and the cooling speed is fast, the product will be transparent with little crystallization. Injection Molding Conditions: Drying: Drying before injection molding is necessary, because PET is highly hygroscopic. It is recommended to dry the material under 120-165℃ conditions for 4 hours to keep the humidity below 0.02%.

PET injection molding parts are mostly used in the bottle preform products. PET has a good rheological property in molten condition and pressure has more effects on viscosity than temperature does. Therefore, we change the rheological property mainly from the pressure. Plastic drying. Due to PET macromolecule contains an aliphatic base, it has certain hydrophilicity.

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.
