Changzhou Hongxinyutai Precision Mold Co., Ltd. (established 2017, factory area 1,000-3,000 m², 51-100 employees) is a dedicated manufacturer specializing in precision injection molded parts for the automotive and new energy vehicle (NEV) industry. Our Injection Molded Automotive NEV Water Pump Plastic Parts are engineered to meet the stringent demands of modern electric vehicle cooling systems. With ±0.1mm dimensional accuracy and flash-free finish, these components offer exceptional reliability and performance, ensuring seamless integration into water pump assemblies. We combine advanced injection molding technology with rigorous quality control to deliver parts that exceed OEM expectations.
Our water pump plastic parts are manufactured using high-grade engineering plastics such as PPS (Polyphenylene Sulfide) or PA66+30% Glass Fiber, providing excellent thermal stability, chemical resistance, and mechanical strength. The parts are designed to withstand the harsh operating conditions of NEV cooling systems, including exposure to coolants, high temperatures, and continuous vibration. The flash-free characteristic is achieved through precision mold design and optimized process parameters, eliminating the need for secondary deburring operations and reducing overall production costs.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
Q: What materials are typically used for these water pump plastic parts?
A: Common materials include PPS (Polyphenylene Sulfide), PA66+30% glass fiber, and PBT+GF, chosen for their thermal and chemical resistance. We can also work with other engineering plastics per your specifications. -
Q: How do you ensure ±0.1mm dimensional accuracy?
A: Our molds are precision-machined using CNC and EDM processes, and we use real-time monitoring during injection molding. Parts are inspected with CMM (Coordinate Measuring Machine) equipment to guarantee the tolerance. -
Q: Are these parts truly flash-free? What about complex geometries?
A: Yes, our mold design and process control eliminate flash even on complex internal features. We use advanced hot runner systems and precise clamp force control to prevent material leakage. -
Q: Can you customize the parts for different water pump designs?
A: Absolutely. We can design and manufacture molds for custom geometries, including impeller housings, inlet/outlet ports, and sealing surfaces. Simply provide your 3D model or drawings. -
Q: What is the typical lead time for new molds and production?
A: Mold fabrication typically takes 30-45 days, followed by trial shots and approval. Once approved, production lead time is 15-25 days depending on quantity. -
Q: Do you provide samples before mass production?
A: Yes, we offer T1 (first trial) samples for dimensional and functional verification. After approval, we proceed to mass production. -
Q: How do you handle quality control for large volumes?
A: We follow a TS16969-based quality system, including incoming material inspection, in-process sampling, and final inspection with statistical process control (SPC). Each batch is accompanied by a certificate of conformance. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ varies by part complexity and material. For standard parts, MOQ is typically 500-1000 pieces. For custom molds, the mold cost is separate, and production MOQ can be negotiated.
