How to operate plastic drum blow molding machine

The extrusion plastic drum blow molding machine needs to heat the raw materials before the product is formed. That is how the extrusion blow molding machine heats the raw material.

Granular plastic raw materials are mixed through the hopper and enter the barrel of the plastic drum blow molding machine. The screw rotates and stirs. At the same time, it is heated by the high temperature of the barrel. Under the action of the gradual increase in the temperature of the barrel, the physical state of the raw material will gradually become a high elastic state. The glass transition of the raw material, and finally become the raw material parison in the molten state, this completes the heating treatment process of the entire raw material, and is also the plasticizing process that the raw material needs to go through before molding production.

Next, the plasticized raw material parison will start the molding process.  how to operate plastic drum blow molding machine screw has been rotating steadily, which is to extrude the plasticized raw materials into the mold with equal pressure and equal amount to form a plastic molding product with a specific shape. After a period of cooling and molding, the production of plastic products is completed.
