Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer specializing in custom injection molding parts for new energy vehicles. With over 7 years of experience, we have developed a deep understanding of the demanding requirements for battery thermal management systems. Our Custom EV Water Pump Injection Molding Parts are engineered to provide reliable, efficient cooling for electric vehicle batteries, ensuring optimal performance and safety. As a factory with 1,000-3,000 square meters of production space and a team of 51-100 skilled employees, we are fully equipped to deliver high-precision, durable components that meet the exact specifications of your thermal management system.
Product Overview: Our injection molded water pump parts are designed specifically for new energy vehicle (NEV) battery thermal management systems. These components play a critical role in maintaining the battery pack at an optimal operating temperature, preventing overheating, and extending battery life. Made from advanced engineering plastics such as PPS, PA66+GF, or PEEK, our parts offer excellent resistance to high temperatures, chemicals, and mechanical stress. Each part is produced using state-of-the-art injection molding machines and precision molds, ensuring tight tolerances and consistent quality batch after batch.
Key Features & Technical Specifications
- High Temperature Resistance: Our materials can withstand continuous exposure to temperatures up to 180°C (for PPS) and short-term peaks up to 240°C, suitable for the harsh environment near battery cells.
- Chemical Resistance: Excellent resistance to glycol-based coolants, electrolytes, and other automotive fluids, ensuring long-term reliability.
- Dimensional Precision: Achieve tolerances as tight as ±0.05mm, critical for sealing and pump efficiency.
- Lightweight Design: Plastic injection molding reduces weight compared to metal parts, contributing to overall vehicle energy efficiency.
- Customizable Integration: We can mold complex geometries including internal channels, bosses, snap-fits, and threaded inserts to meet your specific pump design.
- Surface Finish Options: Available in smooth, textured, or matte finishes to match aesthetic or functional requirements.

| Water Absorption (24h) | ≤ 0.05% |
Advantages of Our Custom EV Water Pump Parts: By choosing our injection molding solutions, you benefit from cost-effective production for high-volume runs, shorter lead times compared to metal machining, and design flexibility that allows for complex internal geometries. Our in-house mold design and manufacturing capabilities (supported by our precision mold division) enable us to prototype quickly and scale up production efficiently. We also offer secondary operations such as ultrasonic welding, vibration welding, and assembly of inserts or seals, providing a complete solution for your water pump module.
Quality Assurance: Our factory is certified under TS16969 (IATF 16949 equivalent), ensuring that every part meets the stringent automotive quality standards. We use advanced inspection equipment including CMM, optical comparators, and leak testing machines to verify dimensional accuracy and functional performance. Each batch is accompanied by a full inspection report upon request.

Frequently Asked Questions (FAQ)
-
What materials are available for your EV water pump injection molding parts?
We offer a range of engineering plastics such as PPS, PA66+GF, PEEK, PPA, and LCP. The material selection depends on your application temperature, pressure, and chemical exposure requirements. Our team can recommend the best material for your specific needs. -
Can you produce parts based on my existing drawings or samples?
Yes, we accept OEM/ODM orders. You can provide 2D/3D drawings (STEP, IGES, PDF) or physical samples. We will conduct a thorough review and suggest modifications if needed to improve moldability and reduce costs. -
What is the typical lead time for custom molds and first samples?
For a new mold, the lead time is approximately 25-35 working days, depending on complexity. Sample production usually takes 7-10 working days after mold completion. We can prioritize urgent projects with expedited fees. -
Do you offer any testing or certification for the parts?
All parts are manufactured under TS16969 quality system. We can provide material certificates, dimensional reports, leak test reports, and other functional tests as required. We also support customer third-party audits. -
What is the minimum order quantity (MOQ) for custom injection molding parts?
Our MOQ for custom parts is typically 500-1000 pieces for first orders, but we can discuss lower quantities for sample runs or pilot projects. For standard parts from existing molds, MOQ may be higher. -
How do you ensure the parts are suitable for battery thermal management applications?
Our materials are selected for their high thermal conductivity (if needed), low moisture absorption, and excellent chemical resistance to coolants. We also design parts to withstand the thermal cycling and vibration environment typical of electric vehicles. Additionally, we can integrate features like O-ring grooves or sealing surfaces to prevent leakage. -
Can you add custom features like ribs, bosses, or threaded inserts?
Absolutely. We have extensive experience molding complex geometries with undercuts, side actions, and hot runner systems. Threaded inserts (brass, stainless steel) can be inserted during molding or post-molding. We can also add color coding, logos, or laser marking. -
What is the shipping method and cost?
We ship via sea, air, or express (DHL, FedEx, UPS) depending on your urgency and budget. For bulk orders, sea freight is the most economical. We can provide a quote including shipping costs to your destination.
