Company Introduction: Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer specializing in precision injection molds and plastic components for the automotive industry. With a factory size of 1,000–3,000 square meters and a dedicated team of 51–100 employees, we have earned the TS16969 quality management certification, ensuring our products meet rigorous automotive standards. Our precision injection molded NEV electric water pump plastic molding delivers a reliable 1000 L/H flow rate and 1.5 bar pressure, designed to optimize cooling performance in new energy vehicles.
Product Overview: This high-precision molded plastic water pump housing is engineered for electric vehicle thermal management systems. It combines lightweight design with superior mechanical strength, corrosion resistance, and dimensional stability. The 1000 L/H flow rate and 1.5 bar pressure ensure efficient coolant circulation, supporting battery pack and motor temperature regulation. Below are the key features and specifications.
Key Features & Benefits
- Precision Injection Molding: Tight tolerances (±0.05mm) ensure perfect fit and sealing, reducing leakage risk.
- High-Flow Design: 1000 L/H nominal flow rate meets the demanding cooling requirements of modern NEV powertrains.
- Optimal Pressure Rating: 1.5 bar operating pressure provides adequate head for coolant circulation without overstressing the system.
- Durable Material: Engineered plastic (e.g., PPS or PA66+GF30) offers excellent chemical resistance, high temperature tolerance (up to 150°C), and long service life.
- Lightweight Construction: Up to 40% lighter than metal alternatives, contributing to overall vehicle weight reduction and range extension.
- Corrosion & Vibration Resistant: Ideal for harsh under-hood environments with exposure to coolant, salt, and vibration.
- Customizable Ports & Mounting: Inlet/outlet diameters and bracket designs can be tailored to your specific pump assembly.
- TS16969 Certified Process: Manufactured under strict quality control, ensuring batch-to-batch consistency and reliability.

Frequently Asked Questions (FAQ)
Q1: What materials are used for the plastic molding?
A: We typically use PPS (Polyphenylene Sulfide) or PA66 reinforced with 30% glass fiber. Both offer high heat resistance and mechanical strength suitable for coolant systems.
Q2: Can the flow rate and pressure be customized?
A: Yes, the pump housing design can be modified to achieve different flow/pressure characteristics. Please provide your specific requirements for a feasibility study.
Q3: What is the minimum order quantity (MOQ)?
A: MOQ depends on part complexity and mold investment. For new molds, MOQ is typically 5,000–10,000 pcs. For existing molds, MOQ may be lower.
Q4: How long does mold development take?
A: Standard lead time for a new injection mold is 25–40 days, including design, tooling, sampling, and testing.
Q5: Do you provide samples for testing?
A: Yes, we offer pre-production samples (typically 5–10 pcs) for your evaluation. Sample costs are negotiable and refundable with bulk orders.
Q6: Is the product compatible with different coolant types?
A: Our plastic materials are compatible with ethylene glycol and propylene glycol based coolants commonly used in EVs. Please confirm your coolant chemistry for verification.
Q7: What quality inspections are performed?
A: We perform dimensional inspection (CMM), pressure testing (1.5x working pressure), flow rate verification, and visual inspection for each batch.
Q8: Can you help with pump assembly integration?
A: Absolutely. We can design the molding to accommodate your chosen motor, impeller, and seal specifications. Our team offers engineering support throughout the project.
