The growth of the new energy vehicle industry has driven rising demand for auto parts such as automotive micro-motors, washer pumps and sensors, imposing stringent requirements on injection-molded housings in terms of dimensional accuracy, material performance and batch consistency. Based in Cixi, Ningbo, Ningbo Zhaoxu Plastic Products Co., Ltd. has long focused on injection molding for new energy auto parts. The company provides mold development and injection molding production for EPS motor housings, window motor housings, air-conditioning motor housings, automotive washer pump housings and various sensor enclosures.

      For automotive plastic parts, Zhaoxu Plastics can achieve a dimensional accuracy of ±0.05 mm. It processes a wide range of engineering plastics including PA66, glass-filled PA66, POM and PBT+GF to meet diverse operating requirements such as temperature resistance, oil resistance, flame retardancy and waterproof sealing. Some sensor housings adopt structural designs reaching IP67 and IP68 waterproof and dustproof ratings. Supported by automated injection molding production lines and a robust batch traceability system, raw materials, production machines and work shifts can be traced for every batch of products, facilitating customers’ quality control.

      The company has established cooperative supply relationships with automotive micro-motor manufacturers and accumulated mass-production experience in EPS electric power steering motor housings, window lifter motor housings, seat adjustment motor housings and other products. Engineers participate in structural evaluation at the early project stage, offering mold flow analysis references and material selection recommendations. Mass production commences only after verification of small-batch samples.

      Beyond new energy automotive housings, Zhaoxu Plastics also undertakes customized production of power adapter enclosures, small home appliance housings, instrument housings and various non-standard special-shaped plastic parts, serving manufacturing enterprises across the Yangtze River Delta and nationwide.
