In addition, we can also provide other automatic production auxiliary equipment for tube preform injection molding, such as: drying machine, automatic loader, chiller, picking machine, conveyor belt and visual inspection system, etc., help you get started preform production quickly. Before you choose PET blowing equipment, you should confirm the neck diameter of the bottle and the hourly production capacity, so that we will provide you with the most suitable solution. Before blowing, put the PET preform into the drying tunnel for heating, then take it out and put it into the blowing machine, and blow the tube preform into the final product. A heat insulator is sometimes placed between the hot runner mold and the injection molding machine. PET bottle blowing equipments are composed of blowing part and drying tunnel. Hot runner molds are used to manufacture PET preforms. The application indudes gas barrier, light barrier and. GDXL provides co-injection PET prefrom complete system solution in the industry as well, up to 72 cavities. Machine with our tube preform mold, it can meet the requirements of high quality and high efficiency. GDXL provides complete PET preform injection molding system with specification of 150T, 300T, 400T and 500T, comprising injection molding machine, preform molds and auxiliary systems. It has super length to diameter ratio and high plasticization rate, and has the advantages of high speed, high efficiency, high stability, and high energy saving. Our high-speed injection molding machine has a variety of models, which can be adapted to PET preform molds with different cavities. In addition, most PET tube preform molds are multi-cavity designs, which can greatly improve production efficiency. Because the volume of the bottle will also affect the thickness, weight and cycle time of the preform. Therefore, you should first determine what’s the capacity of the PET bottles (500ML, 1000ML or 2L) you want to produce. The weight, stretch and transparency of the preform will affect the bottle quality. The PET preform is the foundation of the bottle. PET preform-PET injection molding machine We can provide you with the entire PET preform and bottle production line solution - Custom Design Injection Molding Line Set Up.ġ. The first process is to manufacture the PET preform by an injection molding machine, and the second step is to blow molding into a bottle shape by a blow molding machine. PET bottles are made through two key steps and two different processes. Demark mainly produces Direct-Clamping pet preform injection molding machines With 3 Station Cooling Robot & Electric Plasticization & Two-step Injection and no cutting of valve gate hot runner system pet preform molds(16, 24, 32, 48, 72, 96, 128, 144 Cavities).
