The production process of plastic bottles for cosmetics generally includes the following steps:

Raw material preparation: Select plastic raw materials that meet the requirements, and conduct necessary testing and treatment, such as cleaning, drying, and removing impurities.

Mold making: According to product design and requirements, make corresponding plastic molds. Molds are generally made of materials such as steel and plastic, with certain strength and stiffness, which can ensure the shape and dimensional accuracy of the product.

Injection molding: Place plastic raw materials into a mold, heat and plasticize them through an injection molding machine, and make them into plastic products with a certain shape and size. During the injection molding process, it is necessary to control parameters such as injection pressure, temperature, and time to ensure the quality and accuracy of the product.

Trimming, spraying, labeling: After completing injection molding, it is necessary to perform trimming, spraying, and other treatments on the product to ensure its appearance and quality. At the same time, labeling and other processes need to be carried out for subsequent packaging and delivery.

Packaging and storage and transportation: Finally, the product is packaged and stored and transported according to requirements to ensure the quality and safety of the product during transportation and sales.

Overall, the production process of plastic bottles for cosmetics is relatively complex and requires multiple steps and links to produce products that meet the requirements.
