As a reliable manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in producing high-precision injection molded components for the automotive industry. With over 6 years of experience since our establishment in 2017, we have developed a deep expertise in crafting EV water pump housings using advanced materials like PPA GF35. Our product is designed to meet the rigorous demands of electric vehicle cooling systems, offering leak-proof performance and durable fluid drive capabilities. We are proud to export this component to Hungary and other global markets, ensuring compliance with international quality standards.
This IATF 16949-compliant EV water pump housing (note: our facility is certified under the TS16969 standard, which aligns with automotive quality management principles) is manufactured using PPA (polyphthalamide) reinforced with 35% glass fiber. This material combination provides exceptional thermal stability, chemical resistance, and mechanical strength, making it ideal for continuous exposure to coolant fluids in high-temperature environments. The molding process is meticulously controlled to achieve zero-defect leakage performance, ensuring the housing remains sealed even under extreme pressure fluctuations.
Key Features & Technical Specifications
- Material Advantage: PPA GF35 offers superior heat deflection temperature up to 290°C, low moisture absorption, and excellent dimensional stability, reducing warpage and ensuring long-term reliability.
- Leak-Proof Design: Our proprietary molding technology incorporates precision sealing surfaces and integrated gasket grooves, eliminating the need for secondary sealing operations and achieving 100% leak testing before shipment.
- Coolant Fluid Compatibility: The housing is resistant to ethylene glycol-based coolants, water-glycol mixtures, and oil-based fluids, making it suitable for both BEV (Battery Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle) applications.
- Precision Molding: Our injection molding machines with servo-driven control ensure tight tolerances of ±0.05mm on critical dimensions, allowing for seamless integration with pump assemblies.
- Customization Options: We offer customizable connector interfaces, mounting brackets, and color coding (e.g., black, orange, blue) to match OEM requirements.

Frequently Asked Questions (FAQ)
-
Q: Is this water pump housing compatible with all EV models?
A: Our housing is designed as a customizable component. We can adapt the mounting interface, connector type, and dimensions to fit specific pump assemblies. Please provide your design specifications for a tailored solution. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 500 pcs for standard designs, but we can accommodate smaller quantities for prototyping or sampling. Contact our sales team for details. -
Q: How do you ensure the housing is leak-proof?
A: We perform air leak testing on every part using a pressure decay method, with a maximum leakage rate of 0.01 cc/min at 0.5 MPa. Additionally, we use ultrasonic welding or laser marking for traceability. -
Q: Can you provide material certification for PPA GF35?
A: Yes, we can provide material test reports (MTR) showing mechanical, thermal, and chemical properties. Our material is sourced from reputable suppliers with ISO 9001 certification. -
Q: What is the lead time for production?
A: Typical lead time is 4–6 weeks after order confirmation and sample approval. For urgent orders, we may expedite to 2–3 weeks with additional charges. -
Q: Do you have experience exporting to Hungary?
A: Yes, we have successfully shipped to Hungary and other European countries. Our packaging complies with EU import regulations, and we can arrange FOB, CIF, or DDP terms. -
Q: Is the housing resistant to long-term coolant exposure?
A: Absolutely. PPA GF35 exhibits excellent resistance to hydrolysis and glycol-based coolants for extended periods, as verified by our immersion testing at 120°C for 1000 hours. -
Q: Can you provide samples before bulk production?
A: Yes, we offer free samples for evaluation (shipping cost covered by buyer). We can also produce prototype molds for design validation.
