Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for high-quality OEM plastic components. Since 2017, we have specialized in manufacturing precision injection-molded parts for electric vehicle (EV) thermal management systems. Our OEM Plastic Components for EV Water Pump are specifically designed for battery thermal management systems (BTMS) and liquid cooling applications, supporting 12V or 24V power systems and operating reliably down to -40°C. With a factory of 1,000–3,000 sqm and a team of 51–100 skilled professionals, we deliver components that meet the rigorous demands of modern EV thermal management.
Our components are engineered to withstand extreme temperatures, provide excellent chemical resistance to coolants, and maintain dimensional stability under high-pressure liquid cooling loops. Whether you need a complex water pump housing, impeller, or connector, our expertise in precision mold design and injection molding ensures tight tolerances and consistent quality. We hold TS16969 certification, reflecting our commitment to automotive-grade quality systems.
Key Features & Technical Specifications
- Material Excellence: We use high-performance engineering plastics such as PPA (Polyphthalamide), PPS (Polyphenylene Sulfide), and PA66+GF (Nylon with glass fiber) – all with excellent thermal stability, low moisture absorption, and resistance to ethylene glycol/water mixtures.
- Wide Temperature Range: Designed for -40°C cold start to +125°C continuous operation, ensuring reliable performance in extreme climates.
- Dual Voltage Compatibility: Suitable for both 12V and 24V EV water pump systems, covering passenger cars, buses, and light commercial vehicles.
- Precision Injection Molding: Our molds are CNC-machined with tolerances up to ±0.02mm, ensuring leak-free sealing surfaces and optimal pump efficiency.
- Customizable Design: We accept OEM/ODM orders – from 2D/3D drawings to samples. Finish options include smooth, textured, or laser-marked surfaces.
- Quality Assurance: Every batch undergoes dimensional inspection, material certificate verification, and burst pressure testing (optional).

Frequently Asked Questions
-
Q: What materials are used for these water pump components?
We use high-temperature engineering plastics like PPA, PPS, and PA66+GF. The exact material is selected based on your application requirements (e.g., coolant type, operating pressure, temperature peaks). -
Q: Can you produce components for 12V and 24V pumps?
Yes. Our designs are voltage-agnostic – the plastic parts are compatible with both 12V and 24V pump assemblies. The electrical specifications are managed by the pump motor, which we do not supply. -
Q: Are these components suitable for -40°C start-up?
Absolutely. Our materials are tested for low-temperature impact resistance and maintain dimensional stability at -40°C. We recommend requesting a cold impact test report if needed. -
Q: Do you offer custom mold design and sampling?
Yes. We provide full OEM service: from mold design based on your 3D model, to T1 samples within 25–40 days. Rush orders are available upon request. -
Q: What quality certifications do you hold?
We are TS16969 certified (IATF 16949 equivalent). This ensures our quality management system meets automotive industry standards for production and service parts. -
Q: What is the minimum order quantity (MOQ)?
MOQ depends on the component complexity. Typically, for new molds, the MOQ is 1,000–5,000 pieces. For existing molds, MOQ can be negotiated. -
Q: Can you produce components with specific surface finishes or colors?
Yes. We offer a variety of surface finishes (mirror, textured, matte) and can color-match to your requirement using masterbatch. Custom colors are available for orders above 10,000 pieces. -
Q: How do you ensure leak-tightness in water pump housings?
We use precision mold inserts and gate design to minimize weld lines. Dimensions are controlled within ±0.05mm on critical sealing surfaces. We also offer optional 100% air leak testing (customers can specify the test pressure).
