As a reliable manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. has been dedicated to producing high-quality precision plastic components since 2017. With a factory area of 1,000–3,000 square meters and a skilled team of 51–100 employees, we specialize in automotive parts that demand tight tolerances and long-term durability. Our Auto Electric Water Pump Plastic Components are engineered to meet the rigorous requirements of modern cooling systems, offering exceptional performance in temperature resistance, mechanical strength, and dimensional stability.
These components are manufactured using PPS+GF30 (Polyphenylene Sulfide reinforced with 30% glass fiber), a high-performance engineering plastic known for its outstanding chemical resistance, low moisture absorption, and ability to withstand continuous operating temperatures up to 220°C. The 1x2 cold runner design ensures efficient material utilization and consistent part quality, while the ultrasonic welding process creates a permanent, leak-proof bond between plastic parts. The resulting smooth surface finish reduces friction and improves flow dynamics in the pump assembly.
Below is a summary of key technical specifications for our Auto Electric Water Pump Plastic Components:
| Material | PPS+GF30 |
| Operating Temperature Range | -40°C to 220°C |
| Tensile Strength | ≥ 150 MPa |
| Welding Method | Ultrasonic Welding |
| Runner System | 1x2 Cold Runner |
| Surface Finish | Smooth (Ra ≤ 0.8 μm) |
| Dimensional Tolerance | ±0.05 mm (on critical dimensions) |
Key Features and Benefits
- High-Temperature Resistance: PPS+GF30 maintains mechanical integrity even under prolonged exposure to hot coolant, making it ideal for automotive water pump applications.
- Leak-Proof Ultrasonic Welding: The ultrasonic welding process fuses parts at a molecular level, creating a hermetic seal that withstands pressure fluctuations and thermal cycling.
- Cost-Efficient Cold Runner: The 1x2 cold runner system minimizes material waste compared to hot runner alternatives, reducing overall production costs without compromising quality.
- Optimized Surface Smoothness: A smooth surface finish reduces friction and wear on pump seals, extending the service life of the entire pump assembly.
- IATF 16949 Compliance: Our manufacturing processes are aligned with the stringent automotive quality management standard, ensuring consistent part-to-part quality.
- Customizable Dimensions: We offer flexible design modifications to accommodate specific pump housing geometries, with fast prototyping services available.
At Changzhou Hongxinyutai, we understand the critical role that water pump components play in engine cooling systems. Our team uses advanced injection molding machines and ultrasonic welding equipment to produce parts with tight tolerances and excellent repeatability. Each batch undergoes rigorous dimensional inspection and weld strength testing to guarantee performance.

Frequently Asked Questions (FAQ)
Q1: What is the maximum operating temperature for these components?
A: The PPS+GF30 material can withstand continuous temperatures up to 220°C and short-term peaks up to 240°C, making it suitable for most automotive coolant systems.
Q2: Are these components resistant to common automotive coolants?
A: Yes, PPS+GF30 exhibits excellent chemical resistance to ethylene glycol, water, and other coolants used in modern vehicles, with negligible swelling or degradation.
Q3: What is the typical lead time for production?
A: For standard designs, we typically ship within 30–45 days after order confirmation. Custom tooling may require an additional 4–6 weeks.
Q4: Do you offer samples for testing?
A: Yes, we can provide samples from existing molds or produce prototype parts via 3D printing or soft tooling. Please contact us with your specific requirements.
Q5: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 1,000 pieces for standard parts, but we can negotiate lower quantities for trial orders or custom designs.
Q6: How do you ensure the ultrasonic weld quality?
A: We perform burst pressure tests and cross-section micrographs on a regular basis. Our welding parameters are optimized for each specific geometry, and we use real-time monitoring to maintain consistency.
Q7: Can you customize the surface finish or color?
A: Yes, we can achieve different surface textures (e.g., matte, glossy) and colors through pigmentation. However, note that color may affect material properties; we recommend consulting our engineering team.
Q8: Are your products RoHS compliant?
A: Yes, our PPS+GF30 material is RoHS compliant, and we can provide corresponding declarations upon request.
