Requirements for large hollow blow molding machines

The head of a large-scale China extrusion blow molding machine for raw materials (plastics) separates the two functions of the storage head of the extrusion blow molding machine for hollow raw materials (plastics) and the injection extrusion embryo, which are accomplished by the injection molding mechanism. Thus, the head has the advantage of the continuous head being easy to change colors and materials.
It has the advantages of high repetition precision of billet weight, high plasticizing ability, short changing time and high strength of melt fusion zone. The extrusion blow molding machine for large-scale hollow raw materials (plastics) generally uses a storage head, which has complex internal structure and many parts. Therefore, from the characteristics of the storage head itself, there inevitably exists the shortcomings of long changing time and inaccurate measurement accuracy.
