The plastic varieties used in the hollow blow molding machine include polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resin. Among them, the consumption of high-density polyethylene occupies the first place. It is widely used in food, chemical and liquid processing packaging. High molecular weight polyethylene is suitable for manufacturing large fuel tanks and barrels. Polyvinyl chloride is widely used in the packaging of cosmetics and detergents because of its better transparency and air tightness.
With the development of non-toxic polyvinyl chloride resins and additives, as well as the development of stretch blow molding technology, the amount of polyvinyl chloride containers used in food packaging has increased rapidly, and they have begun to be used for packaging of beer and other carbon dioxide-containing beverages. . Linear polyester material is a new type of material that has entered the field of hollow blow molding in recent years. Because its products have the advantages of glossy appearance, excellent transparency, high mechanical strength and good preservation of the contents of the container, and the advantages of not polluting the environment during waste incineration, it has developed rapidly in packaging bottles, especially It is most widely used in pressure-resistant plastic food containers. Due to the modification of its resin and the progress of processing technology, the use of polypropylene has also increased year by year.
1. The hollow blow molding machine uses a constant pressure thermostat to control the infrared lamp to heat the preform to ensure that the embryo is heated correctly, accurately and stably, independent of the input voltage change.
2. According to the needs of different products, the hollow blow molding machine can be designed with dual-chamber double-stretching cylinder, three-chamber three-cylinder, four-chamber four-cylinder or six-cylinder six-cylinder pulling cylinder design, and the function can be adjusted individually. Use single-chamber single-stretching cylinder to Adjust the machine or try the different needs of the mold.
3. A control system with an automatic alarm barrier function; when an operation error or failure occurs, the computer will display and issue an alarm.
4. Hollow blow molding machine molds are convenient and convenient to replace, and there is no need to adjust the mold thickness within the mold capacity of the corresponding machine.
5. The hollow blow molding machine blows 30ml-5L cold and hot filling plastic bottles or other plastic containers.
6. The production process is fully automated, and multiple machines can also be combined into an automatic production line. The entire production process does not require manual contact with preforms or finished bottles.
