First of all, let's talk briefly about the blow molding machine. The blow molding machine can heat and soften the raw materials, extrude the tubular blank through the extrusion head, inject into the mold, lock the mold, pass compressed air, and blow the mold. Close to the inner wall of the mold, and

1) First put the heated plastic embryo into the mold;2) Use mold clamping cylinder to tighten the mold tightly;3) Use high pressure or mechanical structure to lock the mold;4) Medium and high pressure pre-blowing, and the action of stretching the cylinder at the same time expands the mold;5) High-pr
