The raw materials in the molten state are extruded through a screw extruder.
The extrusion process is quantitative and is extruded according to the amount of raw materials required to produce a product. After extrusion, the raw material parison is formed, and the parison enters the split mold of the hollow blow molding machine.
When a certain amount of parison is extruded, the mold is closed, and at the same time, the bottom is fed with compressed air.
Let the parison expand and form it close to the inner wall of the mold, and then cool through the air ring to complete the production of the product.
The raw materials in the molten state are granular plastic raw materials, which enter the screw barrel through the automatic feeding system of the hollow blow molding machine, are melted by high temperature heating, and are mixed and stirred by the screw to form raw materials in a molten state.
