The invention discloses an extrusion blow molding process for base products, including the following process steps: material drying, feeding, sectional barrel temperature setting, sectional head temperature setting, wall thickness control, mold clamping, cooling and part picking. With a reasonable design, this process overcomes the defects of conventional technologies. The finished products have high strength, high toughness and high cost performance, as well as attractive appearance and diversified shapes. Secondary processing such as polishing, oil spraying and electroplating is not required, and the whole process is eco-friendly. It fills the technical gap in this field and is suitable for large-scale promotion and application.
