The quality of the punching needle and the service life of the punching needle in the automatic blow molding machine have a great relationship with the uniformity of the gap between the cold punches.In order to ensure the correct position and uniform gap between the convex and horizontal and the con

1. The principle of double ring barrel blow molding machineIn simple terms, the working principle of the blow molding machine is similar to blowing bubbles. After the plastic and the hopper enter the extruder barrel, as the screw rotates, it is forced to the direction of the machine head by the thre

Extrusion blow molding machine Extrusion blow molding machine is a machine that can make plastic products. First, the raw material is heated to complete plasticization, extruded through an extruder to form a tubular parison, injected into the mold, compressed air is introduced into the mold, the parison is inflated, adhered to the inner wall of the mold, and finally demolded after cooling , to obtain a variety of hollow plastic products.

When the molten plastic parison falls on the open mold, the electrostatic charge will cause the following problems:1. When there is more than one parison on each mold, the static charge always has the same polarity. This way the parisons will repel each other. In this case, it is usually impossible

Before the new mold blow molding or the machine to replace other mold production, the mold test is an essential part.The result of the test will directly affect the smooth production of the factory.Therefore, it is necessary to follow reasonable operation steps and record useful technical parameters

The hollow blow molding machine is used to produce hollow products mainly made of HDPE plastic materials, such as oil drums, chemical drums, pesticide bottles and other special-shaped parts. How to properly use and maintain the hollow blow molding machine to extend its life?1. Inspection of machine
