As a leading manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in precision plastic components for automotive thermal management systems. Our Automotive NEV Water Pump Plastic Parts for Battery Cooling System are engineered with a high flow rate design to meet the rigorous demands of new energy vehicles. With over 7 years of experience and a dedicated team of 51–100 skilled employees, we deliver components that ensure optimal battery temperature regulation, enhancing vehicle safety and performance.
These plastic parts are manufactured using advanced injection molding technology and premium engineering plastics, offering excellent chemical resistance, dimensional stability, and long-term durability. The high flow rate geometry is optimized to reduce hydraulic resistance, maximizing coolant circulation efficiency for battery packs. Whether you need a complete pump assembly or individual components, our products are fully customizable to your specifications.
Key Features & Technical Specifications
- High Flow Rate Design: Specially engineered impeller and volute geometry to achieve flow rates up to 30 L/min or higher, tailored to your system requirements.
- Wide Temperature Range: Reliable operation from -40°C to +125°C, suitable for extreme climates and thermal cycling conditions.
- Chemical Compatibility: Resistant to coolants (water-glycol mixtures), oils, and other automotive fluids, preventing degradation over time.
- Precision Molded: All parts are produced with tight tolerances (±0.05 mm) to ensure leak-free assembly and consistent performance.
- Lightweight & Compact: Plastic construction reduces overall pump weight by up to 40% compared to metal alternatives, contributing to vehicle energy efficiency.
- Customizable Options: Available in various colors, connector types, and mounting configurations to match your existing pump design.

Frequently Asked Questions (FAQ)
-
Q: What materials are used for these water pump plastic parts?
A: We primarily use high-strength engineering plastics like PPA (polyphthalamide) and PA66 reinforced with 30% glass fiber. Other materials such as PPS or PEEK are available on request for specific chemical or temperature requirements. -
Q: Can you customize the flow rate design for my pump?
A: Yes, our high flow rate design is fully customizable. We can adjust impeller geometry, volute shape, and port sizes to meet your target flow and pressure specifications. -
Q: Are these parts compatible with standard automotive coolants?
A: Absolutely. The materials we use are tested for compatibility with ethylene glycol/water mixtures, as well as other common coolants used in NEV battery cooling systems. -
Q: What is the typical lead time for custom molds and parts?
A: Mold development typically takes 4–6 weeks, and mass production lead time is 2–4 weeks after mold approval, depending on order quantity. -
Q: Do you offer any quality certifications or test reports?
A: Yes, we are TS16969 certified. We can provide material certificates, dimensional inspection reports, and functional test data upon request. -
Q: What is the minimum order quantity (MOQ)?
A: For new custom parts, MOQ is usually 500–1000 pieces. For existing standard designs, MOQ can be as low as 100 pieces. Please contact us for details. -
Q: Can you assist with design optimization for better performance?
A: Definitely. Our engineering team can perform CFD analysis and recommend design improvements to maximize flow rate and minimize pressure drop. -
Q: How do you ensure the parts are leak-proof in assembly?
A: We maintain tight tolerances on all sealing surfaces and use advanced molding processes to prevent warpage. Optional O-ring grooves or ultrasonic welding features can be added to enhance sealing.
