Changzhou Hongxinyutai Precision Mold Co., Ltd. is a professional manufacturer specializing in precision injection molding and mold making since 2017. We are proud to present our Custom Injection Molded Parts for Auto EV Water Pump in Battery Thermal Management System, designed to meet the rigorous demands of modern electric vehicles. These components are engineered to operate reliably under 12V/24V electrical systems, ensuring optimal coolant circulation and thermal stability for battery packs. With our TS16969-certified production facility (1,000-3,000 sqm) and a dedicated team of 51-100 skilled workers, we deliver high-precision, durable parts that enhance the performance and safety of EV thermal management systems.
Our injection molded parts are crafted from advanced engineering plastics, selected for their thermal resistance, chemical stability, and mechanical strength. Whether you need a complex housing, impeller, or connector, our custom solutions are tailored to your exact specifications. Below we detail the key features, technical parameters, and benefits that make our products a reliable choice for global automotive OEMs and Tier-1 suppliers.
Key Features & Technical Specifications
- Material Options: We offer a wide range of thermoplastics including PA66, PPS, PEEK, and PP, all with high heat deflection temperature (up to 260°C) and excellent chemical resistance to coolants and electrolytes.
- Precision Tolerances: Achievable tolerances as tight as ±0.02 mm, ensuring leak-free sealing and proper fitment with pump assemblies.
- Voltage Compatibility: Designed for 12V and 24V DC systems, our parts maintain stable dimensional integrity under varying electrical loads.
- Custom Mold Design: In-house mold design and manufacturing allow rapid prototyping and low-cost tooling changes. We can incorporate features like threaded inserts, metal overmolding, and snap-fit connections.
- Surface Finish: Options include textured, glossy, or matte finishes, with the ability to add laser marking for part identification.
- Quality Control: 100% inspection on critical dimensions, material testing, and pressure testing upon request.
| Parameter | Typical Values |
| Operating Temperature Range | -40°C to +150°C |
| Tensile Strength | ≥ 60 MPa (depending on material) |
| Flame Rating | UL94 V-0 or V-2 (optional) |
| Dielectric Strength | ≥ 15 kV/mm |
| Mold Life | 500,000 – 1,000,000 shots |
Benefits to customers: By choosing our custom injection molded parts, you gain a partner who understands the critical role of the battery thermal management system. Our components help reduce weight (plastic vs. metal), resist corrosion, and lower manufacturing costs compared to metal alternatives. The tight tolerances reduce assembly errors and increase the lifespan of the water pump. With our TS16969-certified quality management system, you can be confident in consistent, repeatable production for high-volume orders.
Our factory in Changzhou, Jiangsu, China, covers 1,000-3,000 square meters and houses advanced injection molding machines from 50 to 300 tons. We export to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. With a dedicated team of 51-100 employees, we maintain short lead times (typically 15-25 days for mold production, 7-15 days for mass production). We also offer flexible shipping options from Jiangsu, Shanghai, and Shenzhen ports.
Trusted by global clients, our parts have been used in various EV platforms. We are committed to continuous improvement and can adapt to your specific requirements, such as custom colors, special packaging, or unique material certifications.

Frequently Asked Questions (FAQ)
-
Q: Can you produce parts for 12V and 24V water pumps?
A: Yes, our parts are designed to work with both 12V and 24V electrical systems. The material selection and dimensional stability ensure reliable performance under these voltage conditions. -
Q: What is the minimum order quantity?
A: MOQ depends on the complexity and mold cost. For standard parts, MOQ can be 1,000 pieces. For custom molds, we can discuss lower quantities for prototyping. -
Q: Do you provide mold design service?
A: Yes, we have in-house mold design engineers who can create molds based on your 3D drawings or samples. We support both new tooling and modification of existing molds. -
Q: What materials are suitable for high-temperature coolant?
A: We recommend PPS or PEEK for continuous exposure to hot coolant (up to 150°C). PA66 is also an option for moderate temperatures. We can advise based on your application. -
Q: How do you ensure part quality?
A: We are TS16969 certified. Our quality control includes incoming material inspection, in-process checks, and final dimensional measurement using CMM equipment. We also offer pressure testing if required. -
Q: Can you add metal inserts or overmolding?
A: Absolutely. We frequently produce parts with threaded brass inserts, stainless steel sleeves, or overmolded metal connectors for electrical terminals. -
Q: What is the typical lead time for a new mold?
A: Mold production typically takes 20-25 days after design approval. For urgent projects, we can expedite to 15 days with a surcharge. -
Q: Do you ship samples before mass production?
A: Yes, we can provide samples (T0 or T1 samples) for your testing and approval. Sample cost is negotiable and refundable upon order.
