The objective of the present invention is to provide a single-blow blow molding process for automotive washing pots. The process is characterized by the following steps: Step a, preheating the temperature of the blow molding machine; Step b, extruding parisons; Step c, performing single-blow forming under vacuum; Step d, opening the mold and withdrawing the core after blow molding. Adopting the single-blow process optimizes detail processing during production, conducts blow molding in gradual stages, improves product uniformity, reduces cracks at connecting parts, lowers defective rate, minimizes material waste and cuts down processing costs.
