![]() The optimum temperature range can be set between 270 and 295 ° C using a shot-to-air method.Įnhance grade GF-PET can be set at 290-315 ° C. The venting slot depth must not exceed 0.03mm otherwise, the flash will easily occur. Preforms are about 12 mm thick, while insulators have to withstand high pressure. A heat insulator is sometimes placed between the hot runner mold and the injection molding machine. Hot runner molds are used to manufacture PET preforms. Injection systems with temperature control sections and low friction heat are required since PET has a stable time after melting and high melting point, and the actual weight of the plastic should be 2/3 of the one-shot amount of machine injection. Recyclable materials should be no higher than 25%, and they should be thoroughly dried before use. It requires drying at 150 ☌ for at least four hours, generally 170 ☌, over three to four hours, before processing. PET loses molecular weight when moisture levels exceed the limit the product turns color and becomes brittle. Also, due to their presence, PET has a phospholipid-based structure. Plastic Processingĭue to its lipid-related nature and its hydrophilicity, PET pellets are very sensitive to water at high temperatures. In this situation, the fluidity of the melt is often affected mainly by pressure. As of today, GF-PET is the most popular polymer among customers, which is mainly used in preform injection.Ĭonsequently, the properties of PET in a liquid state are much better, and pressure is more important than temperature in terms of viscosity. Polyethylene terephthalate (PET) is a naturally occurring thermoplastic polymer commonly used in plastic products. This service allows you to make everything you need in one convenient location.
