The modern development of hollow blow molding machines originated in the 1930s. After years of development and changes, today’s hollow blow molding machines are involved in various industries. The cost of blow molding technology and equipment is low, and complex hollow products can be molded.

Hollow blow molding equipment should be maintained regularly at intervals of time. Usually, the equipment management personnel will guide the blow molding equipment. There are mainly 10 steps in the regular maintenance of blow molding equipment. Let me take you to understand it together.

I Why is the extruded parison prone to bending? How to solve it?(1) The main reason for the bending of the parisonIn the extrusion blow molding process, the main reasons for the bending of the parison are as follows.①The flow channel in the die is not smooth or the center of the die is not centered.

(1) Factors affecting the sagging of the parisonIn the process of parison extrusion, the parison is prone to sag due to its own weight, resulting in uneven wall thickness of the parison. The more severe the sagging, the greater the unevenness of the parison wall thickness. Therefore, during the mold
