The main raw material of daily chemical bottles is PE plastic, an environmentally friendly material, suitable for food and tableware packaging, and has little harm to the human body. The size and specifications of the bottle mouth will also affect the sealing and compatibility of the bottle.
Through the injection molding process, PE plastic is injected into the mold to form a bottle embryo. The design parameters such as the size, weight and wall thickness of the bottle embryo are crucial to the quality of the final bottle. The plastic blow molding machine produced by Kingplas Machinery can be used to blow PE daily chemical bottles of different specifications.
The molding process of PE daily chemical bottles is mainly divided into one-step method and two-step method. The one-step method completes the three processes of injection molding, stretching and blowing in the same machine, which has the advantages of power saving and high production efficiency. The two-step method is to separate the two processes of injection molding and stretch blowing, which is suitable for investment by small and medium-sized enterprises and has the characteristics of high flexibility.
The PE daily chemical bottles after molding need to be surface treated to improve their appearance quality and smoothness. Common surface treatment methods include polishing, pickling and coating.
The PE bottles after surface treatment need to be strictly inspected, including appearance inspection, size measurement and pressure resistance test, etc., to ensure that their quality meets the standards. PE bottles that pass the inspection will be placed in cartons for packaging.
