PET Preform Mould. The chemical name of PET is polyethylene terephthalate. Nowadays, GF-PET is mostly used by customers, mainly for preforms. The rheology of PET in the molten state is better, and the influence of pressure on viscosity is greater than that of temperature. Therefore, the pressure is mainly used to modify the fluidity of the melt.

It can be measured by air-shot method, ranging from 270-295, and enhanced grade GF-PET can be set to 290-315. Injection speed; Generally, the injection speed should be fast to prevent premature coagulation during injection. But if too fast, the shear rate is high, making the material brittle. The shot is usually completed within 4 seconds.

PET consists of polymerized units of the monomer ethylene terephthalate, with repeating (C 10 H 8 O 4) units. PET is commonly recycled, and has the number 1 as its recycling symbol. Depending on its processing and thermal history, polyethylene terephthalate may exist both as an amorphous (transparent) and as a semi-crystalline polymer. The

All about PET Injection Molding Process - Alleychohttps://alleycho Lisong Low Shear High Plasticization PET Preform Machine /pet-injection-molding-process

Apr 07, 2020 · PET can only be molded by a optimized PET injection molding machine. It is best to choose a mutant screw with a reverse ring at the top, which has a large surface hardness and wear resistance, and the ratio of the length to diameter ratio not L/D = (15~20):1 compression is about 3:1.

Do you know the whole process of PET injection molding?www.fuhrung Lisong Low Shear High Plasticization PET Preform Machine /technical-blog/pet-injection-molding-process.html
