In daily use, there will always be abnormalities and faults. How about the ability of the after-sales service center of the manufacturer? Can professional personnel be arranged for on-site maintenance in the shortest possible time? According to the sales qualification, as well as engaged in the length of the sales cycle and the length of time and other factors to compare, and the formal experience of rich, responsible manufacturers, to ensure that there is no use of worries. Avoid the trouble caused by future use, there is always damage and maintenance problems.
It is well known that the core technology of blow molding machine in the production process is the control of temperature. Now let’s follow the small series of energy-saving blow molding machine manufacturers to understand some simple knowledge in heating.
Common blow molding machine blow plastic film plastic extruder screw is divided into three sections: feeding section, melting section, homogenization section. At the end of the feeding section, to enter the beginning of the melting section, according to the melting theory, its temperature should also be viscous flow temperature. The viscosity temperature of blow molding resin is PP: 164-175 degrees Celsius, PE: 105-135 degrees Celsius, PA: 195-210 degrees Celsius. The temperature at the entrance of the feeding section is lower to prevent the viscous flow of resin blocking the feeding mouth, and the resin keeps compressing in the feeding section and crowding out from the feeding mouth. According to the difference in configuration and layout, the feeding port is not electrically heated, but the absolute barrel heat transfer, the feeding port temperature is about 50-90 degrees. Even if the temperature of the feeding section is determined. The inlet is 49.9-90.1 degrees Celsius, and the end is equal to the melting point or viscous flow temperature.
The above is the important content of simple knowledge about the maintenance and heating of energy-saving blow molding machine.
