Because the pet plastic bottles with good materials can be recycled and reused, and their safety, hygiene and transparency are high, they have become the preferred plastic bottle material for various manufacturers in their production. In addition to pet plastic bottles that we often see daily for drinking water, cosmetics, fruit juices, etc., the pharmaceutical industry and the cosmetics industry also use pet plastic bottles with better materials for packaging. What are the requirements when making pet plastic bottles with pet materials?

1. Material drying before processing. The fluidity of pet material in the molten state is relatively good, and pressure has a greater influence on viscosity. Therefore, the fluidity of the solution is mainly changed from pressure to make pet plastic bottles. Because the pet macromolecule contains a fat base and has a certain degree of hydrophilicity, the particles are sensitive to water at high temperatures. When the moisture content exceeds the limit, the molecular weight of the pet will decrease during processing, and the product will become colored and brittle. Therefore, the material must be dried before processing. Second, the choice of injection molding machine, injection molding machine uses pet because its stable time after the melting point is short and the melting point is high, so it is necessary to use a plastic system with more temperature control sections and less self-friction heat during plasticization for pet plastics The making of the bottle. 3. Molds and gates Mold and gate design pet preforms are generally formed with hot runner grinding tools. Generally, there is a heat shield between the mold and the injection molding machine template, and the heat shield needs to be able to withstand high pressure. 4. Sol temperature and injection speed The sol temperature can be measured by the air injection method, and the injection speed is generally fast, which can prevent premature solidification during injection, but too fast will make the material fragile. Usually the injection is completed in a few seconds. It can be seen that pet plastic bottles made of pet materials need to meet very high requirements. Therefore, whether it is to choose pet plastic bottle production equipment, or the selection of production technology and production personnel, manufacturers must strictly control and select strictly. In this way, we can produce high-quality pet plastic bottles and supply popular pet plastic bottles.
