Metal steel drums are very common in daily life, and many products are also packaged in metal steel drums, so the market demand for metal steel drums is also increasing. Not only that, the number of manufacturers responsible for the production of metal steel drums continues to increase. The brands of metal steel drums in the market are very diversified, and consumers need to choose. In order to be able to select suitable and practical metal steel drums, the following are the factors that affect the performance of metal steel drums. 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 metal steel barrel product and the extruder screw. The screw speed Control at 10 ~ 70r/min. 3. Hydraulic system pressure: In Tianjin metal steel drums, the pressure of the hydraulic system of small and medium-sized hollow molding machines is adjusted between 8 and 14 MPa, which is mainly adjusted according to the molding characteristics of blow-molded products. , the pressure of the hydraulic system can be adjusted to work under a lower pressure state, which is beneficial to energy saving and prolonging the service life of the blow molding machine.
