The long-term use temperature of PET preform mould can reach 120 ℃, and its electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance, creep resistance, fatigue resistance, and friction resistance are poor. , dimensional stability is very good.
What are the advantages of using PET preform mould?
What are the areas of use of PET preform mould?
What is the role of PET preform mould in the production process?
1. It is very important to save costs for users. PET preform mould should be designed to have interchangeable parts, such as screw mouth, gram weight, cavity, core, etc. In this way, changing a pair of moulds for different inserts can achieve a variety of bottle gram weights ,shape.
2. For the clamping structure, we adopt a double-cone positioning design, which can avoid defects such as flash, different sizes, and eccentricity after molding.
3. Use advanced processing equipment to process the preform mold with high precision, and also use equipment such as bridge-type three-coordinate measuring instrument and articulated arm measuring instrument to control the precise size of the mold.
4. After the manufacture of PET preform mould is completed, we will carry out a series of running inspection tests in accordance with the company's quality standards, and all the tests will meet the requirements before shipment.
5. We will provide spare parts, such as core/cavity inserts, other replaceable mold accessories, so that damaged parts can be quickly replaced.
1. The core and cavity of our PET preform mould are made of S136 steel after heat treatment to ensure hardness and life, up to 500 moulds.
2. The hot runner system with heating elements is used to speed up the flow of plastic in the molten state, save materials, and effectively ensure the quality stability of plastic products.
3. For example, mineral water bottles, soda carbonated beverage bottles, tea beverage bottles, etc., these are all based on quantity, and the number of mold cavities determines the benefit. We achieve a maximum of 128 cavities.
The preform factory will inject the purchased raw materials according to the color requirements of the customer's order, and inject the preforms with the toner that has been adjusted in proportion. The transparent ones do not need to add toner. Injection molding of preforms, pumping the raw materials into the injection molding machine, melting at a high temperature of more than 300 degrees, and injecting them into the mold, and then the water circulation of the PET preform mold is often used to rapidly cool and form. Through the tail shearing machine, the flow is automatically cut off. In order to prevent the preform from scratching, the PET preform mould is operated by a robot. The injection-molded preforms are packed in boxes and sent to the blowing factory for the next blowing session.
