SGB ??series weighing-type mixer for mixing materials for plastic injection, extrusion or blow molding process on a variety of raw materials needed for accurate mix ratio by weight of usage scenarios. The series controller uses the German Siemens PLC control system and advanced ingredients algorithm, at each start automatically calibrated to ensure accuracy accurate, easy to learn. The series uses high-precision weight sensor so that the error batch mixing ratio (the ratio depending on the proportion of the size of the set) can be controlled in ± 0.1% ~ 0.3%. Types need to be addressed according to the amount and the amount per hour to choose the right model, the series is divided into twelve kinds of models.
