Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner in precision injection molding for electric vehicle components. Our Precision EV Water Pump Housing is engineered using advanced PPA GF35 (Polyphthalamide with 35% glass fiber) material, renowned for its exceptional hydrolysis resistance. This product is specifically designed to meet the rigorous demands of modern electric vehicle cooling systems, ensuring long-term reliability and performance under extreme conditions. Backed by our TS16969 certified quality management system, we deliver components that meet the highest automotive industry standards.
Our injection molding process achieves precision tolerances as tight as ±0.05mm, ensuring perfect fit and function in your EV water pump assemblies. The material’s hydrolysis resistance prevents degradation in hot coolant environments, extending the lifespan of the pump. With a factory size of 1,000–3,000 square meters and a dedicated team of 51–100 employees, we have the capacity to handle both prototyping and mass production. Our strategic location in Changzhou, Jiangsu, China, allows efficient shipping to major ports worldwide.
Key Features & Technical Specifications
- Material: PPA GF35 – excellent mechanical strength, thermal stability (up to 230°C continuous), and outstanding hydrolysis resistance.
- Precision Tolerances: ±0.05mm on critical dimensions, achieved through high-precision molds and CNC machining.
- Hydrolysis Resistance: Specially formulated to withstand long-term exposure to hot water/glycol coolant mixtures without swelling, cracking, or loss of mechanical properties.
- Application: Ideal for electric vehicle water pump housings, battery cooling systems, and thermal management modules.
- Certification: Manufactured under TS16969 (IATF 16949 equivalent) quality system, ensuring consistent part quality and traceability.
- Customization: Available in multiple colors (black, natural, etc.) and can be tailored to customer-specific designs (including insert molding, overmolding, or complex geometries).
- Surface Finish: Smooth, free of flash, with optional textured or matte finishes as required.

Frequently Asked Questions (FAQ)
- What is PPA GF35 and why is it used for EV water pump housings? PPA GF35 is a polyphthalamide reinforced with 35% glass fiber. It offers high strength, excellent thermal resistance, and superior hydrolysis resistance, making it ideal for hot coolant environments in electric vehicles.
- Does your product have certification for automotive use? Yes, our manufacturing process is certified under TS16969 (equivalent to IATF 16949), ensuring compliance with automotive quality standards.
- Can you produce housings based on our custom design? Absolutely. We accept custom drawings and can provide DFM feedback to optimize the design for injection molding. Lead time for mold development is typically 30–45 days.
- What is the minimum order quantity (MOQ)? For new projects, the MOQ is 1,000 pieces. However, we can accommodate lower quantities for prototyping or sample orders.
- How do you ensure the hydrolysis resistance of the material? We use only prime-grade PPA GF35 from reputable suppliers and conduct in-house testing (e.g., immersion in hot coolant at 130°C for 1000 hours) to verify performance.
- What are the typical dimensional tolerances? Our standard precision is ±0.05mm on critical features. Tighter tolerances (e.g., ±0.02mm) can be achieved upon request.
- Do you offer color matching or special surface finishes? Yes, we can match any RAL or Pantone color. Surface finishes available include smooth, textured, or matte.
- How do you ship to Slovakia or other European countries? We ship via sea or air from Chinese ports. For European customers, typical sea freight takes 25–35 days. We can also arrange door-to-door delivery if needed.
