1. Processing temperature: The processing temperature of bottle-shaped blow molding products is mainly related to the characteristics of the plastic raw materials and equipment used. In general, small and medium barrel blow molding products generally use HDPE or a blend of HDPE and LDPE with good fluidity. The processing temperature is between 130 and 180 ° C. The processing temperature of a few materials may be higher than 180. ℃. The temperature is set from low to high in order from the inlet of the extruder in order to facilitate the normal progress of processing and molding.
2. Extruder screw speed: The screw diameter of the extruder system of the medium-sized hollow molding machine is small, and the screw speed can be relatively high. The speed can be adjusted according to the characteristics of the iron barrel product and the extruder screw, and the screw speed can be controlled. 10 ～ 70r / min.
3.Hydraulic system pressure: In the iron bucket, the pressure of the hydraulic system of the small and medium-sized hollow molding machine is adjusted between 8 and 14 MPa. It is mainly adjusted according to the molding characteristics of the blow molded product. Adjusting the pressure of the hydraulic system to work in a lower pressure state is conducive to saving energy and extending the service life of the hollow molding machine.https://www.fhpails.com/
