Hollow blow molding machine

Short Description:

Principle introduction:

simply speaking, the blow molding machine is to blow the melted liquid plastic into different molds by using the wind force to obtain various types of blow molding products.The detailed principle process is that with the rotation of the screw, the screw is forced to push to the direction of the head. Due to the resistance of the filter screen, the splitter plate and the die at the head, and the gradual reduction of the capacity between the screw threads, the forward material is subject to great resistance. At the same time, it is heated by the heat from the barrel. On the other hand, the plastic is compressed, sheared and heated during the movement A lot of heat is produced by the friction between the barrel and screw under the action of equal stirring force. The temperature of the plastic in the barrel is rising continuously. After bending and plasticizing, the plasticized plastic is extruded from the die with equal pressure and quantity, which is called plastic products with certain shape. After cooling and shaping, the extrusion work is completed.
