In the process of shaping the iron barrel, there are many factors that affect the performance of the iron barrel, and the most important ones are the air blowing pressure, the hydraulic system pressure, the processing temperature, and the screw speed of the extruder.

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. Under normal circumstances, small and medium-sized barrel blow molding products generally use HDPE with good fluidity or a blend of HDPE and LDPE. The processing temperature is between 130 and 180 ° C, and the processing temperature of a few materials may be higher than 180 ° C. °C. The temperature is set from low to high at the feed port of the extruder in order to facilitate the normal progress of processing and molding.

2. The screw speed of the extruder: 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. At 10 ~ 70r/min.

3. Hydraulic system pressure: In the iron barrel, the pressure of the hydraulic system of the small and medium-sized hollow molding machine is adjusted between 8 and 14 MPa, which is mainly adjusted according to the molding characteristics of the blow-molded products. Adjusting the pressure of the hydraulic system to work in a lower pressure state is beneficial to energy saving and prolonging the service life of the blow molding machine.
