The invention belongs to the field of blow molding technology and provides a waste material extrusion blow molding system. By recycling and reusing production scraps, the system is eco-friendly, low-cost and free of secondary pollution. The molded products feature high surface gloss without weld line defects, eliminating subsequent electroplating and spraying processes for covering weld lines. Negative pressure traction is applied to pull the parison into the mold cavity quickly and stably after extrusion. The short forming cycle prevents excessive crystallization of the parison, avoids material accumulation and difficult molding, reduces defective rates, saves working hours and improves productivity. The finished parts have high strength, high toughness and cost performance, with diversified appearances and environmentally friendly production processes.
