The head of the large hollow raw material (ie plastic) hollow blow molding machine separates the two functions of the storage material and the injection-extruded embryo in the hollow blow molding machine storage head of the hollow blown raw material (ie plastic), The injection plasticizing mechanism is completed, so that the machine head has the advantage that the continuous head is easy to change color and refuel.

The parison weight is high in repeatability, high in plasticizing ability, short in color change and refueling time, and high in strength of the fusion zone. Blowing large hollow raw materials (ie plastic) hollow blow molding machine generally adopts the storage type machine head, the internal structure is complex, and there are many parts. Therefore, from the characteristics of the storage type machine head, there is inevitably long time for color change and refueling. Accuracy is not allowed.

The large-scale hollow blow molding machine is a comprehensive hollow blow molding machine that combines the injection molding mechanism of the injection molding machine with the blow molding mechanism of the hollow blow molding machine, and absorbs and exerts the respective advantages of the two machines.

The parison weight is high in repeatability, high in plasticizing ability, short in color change and refueling time, and high in strength of the fusion zone. Extrusion blown large hollow plastic hollow blow molding machine generally adopts the storage type machine head, the internal structure is complex, and there are many parts. Therefore, from the characteristics of the storage type machine head, there is inevitably long time for color change and refueling, and the measurement accuracy is not allowed. Disadvantages. The machine head of the large-volume hollow plastic blow molding machine separates the two functions of the storage material and the injection-extruded embryo in the squeezing blow molding machine of the hollow plastic hollow blow molding machine, and is completed by the injection plasticizing mechanism. In this way, the handpiece has the advantage that the continuous handpiece is easy to change color and refuel.
