The production process of Pet plastic preforms is a complex and delicate process involving multiple links and technologies. Foshan Heyan Mould Co., Ltd., as a leader in the design and manufacture of preform moulds, has a deep understanding and rich experience in the production process of Pet plastic preforms. The following is a detailed analysis of the production process of Pet plastic preforms combined with the professional perspective of Foshan Heyan Mould.
1. Preparation of PET raw materials
In the production process of Pet plastic preforms, the preparation of raw materials is the basis. As a professional preform mould factory, Foshan Heyan Mould has strict standards for the selection and proportion of PET raw materials. We mix PET raw materials in a certain proportion and add auxiliary materials such as color masterbatch and additives to ensure the uniform mixing of raw materials, providing a solid foundation for subsequent production. At the same time, Foshan Heyan Mould also pays attention to the quality inspection of raw materials to ensure that each batch of raw materials meets production requirements.
2. Preform extrusion
Preform extrusion is one of the key steps in the production of Pet plastic preforms. Foshan Heyan Mould uses advanced extrusion machines to extrude the mixed PET raw materials evenly and stably through the extruder to form a cylindrical bottle embryo. In this step, we strictly control the temperature and pressure of the extruder to ensure that the PET raw materials can be fully melted and evenly extruded, providing high-quality bottle embryos for the subsequent molding process.
3. Bottle embryo pre-stretching
Pre-stretching is an important link to enhance the toughness and strength of the bottle embryo. Foshan Heyan Mould uses a professional pre-stretching machine to pre-stretch the bottle embryo, making it easier to form the desired bottle shape in the subsequent heating and molding process. Through pre-stretching, the molecular structure of the bottle embryo is optimized, thereby improving the overall performance of the bottle.
4. Bottle embryo heating molding
Heating molding is the core step in the production of Pet plastic bottle embryos. Foshan Heyan Mould has advanced heating machines and mold design technology. After the pre-stretched bottle embryo is heated to a certain temperature, it is molded through the mold. In this step, we strictly control the heating temperature and mold design to ensure that the bottle can accurately and quickly form the desired appearance shape. At the same time, we also pay attention to the maintenance and maintenance of the mold to ensure the accuracy and life of the mold.
5. Bottle cooling and shaping
Cooling and shaping is a key step to ensure the stability of the bottle shape. Foshan Heyan Mould uses a professional cooling machine to cool the formed bottles. By controlling the cooling temperature and time, we ensure that the bottle can be quickly shaped and maintain a stable shape. At the same time, we also pay attention to the temperature uniformity during the cooling process to avoid deformation or cracks of the bottle due to uneven temperature.
6. Bottle cutting
Cutting is the last key step in the production of Pet plastic bottle blanks. Foshan Heyan Mould uses advanced cutting machines to accurately cut the shaped bottles. We accurately control the cutting length according to customer needs and product design requirements to ensure that every bottle meets the specifications.
7. Bottle testing
Quality testing is an important part of ensuring product quality. Foshan Heyan Mould has complete testing equipment and processes to conduct strict appearance, size, weight and other tests on the cut bottles. Through testing, we ensure that every bottle meets the quality requirements and provides customers with high-quality products.
8. Bottle cleaning and packaging
After the bottle is tested and qualified, we also need to clean and package the bottle. Foshan Heyan Mould uses professional cleaning machines and packaging equipment to thoroughly clean the bottles and remove surface stains and residues. Then, we package the cleaned bottles to ensure that they are not contaminated or damaged during transportation and storage.
In summary, the production process of Pet plastic preforms includes multiple steps such as raw material preparation, preform extrusion, pre-stretching, heating molding, cooling and shaping, cutting, testing, cleaning and packaging. Foshan Heyan Mould Co., Ltd. relies on its professional technology and equipment advantages to strictly control process parameters and equipment status at every link to ensure that the quality and appearance of the products meet the requirements. At the same time, we also pay attention to environmental protection and sustainable development, actively promote and adopt environmental protection technologies and materials, and contribute to protecting the environment.
Foshan Heyan Precision Mould Technology Co., Ltd.'s main business is preform moulds, bottle blowing moulds, bottle cap moulds and other products. It has a strong engineering, R&D, technology and sales team, advanced processing equipment and rich project experience.
