As a leading manufacturer specialized in precision molds and plastic parts, Changzhou Hongxinyutai Precision Mold Co., Ltd. (est. 2017) proudly presents our OEM Electronic EV Water Pump Plastic Parts – engineered with ultrasonic welding support and reinforced with high-grade Gröditz GPM58 steel. These components are designed to meet the demanding requirements of electric vehicle thermal management systems, delivering reliable performance, durability, and tight tolerances. With our TS16969-certified production facility and 51-100 skilled employees, we ensure every part meets international quality standards.
Our plastic parts for electronic water pumps are manufactured using advanced injection molding techniques, combined with ultrasonic welding capability for secure assembly of multi-material components. The integration of Gröditz GPM58 steel – a premium tool steel known for its high wear resistance and dimensional stability – provides exceptional strength at critical stress points, extending the service life of the pump assembly. Whether you need a complete pump housing, impeller, or connector components, our OEM solutions offer flexibility and precision.
Below we highlight the key features and technical specifications of our product:
- Material Excellence: High-performance engineering plastics (e.g., PPS, PPA, PEEK) combined with Gröditz GPM58 steel inserts for enhanced mechanical properties.
- Ultrasonic Welding Ready: Designed with optimized joint geometry and energy directors to facilitate reliable ultrasonic welding, reducing assembly time and improving leak-proof performance.
- Precision Molding: Tolerances down to ±0.05 mm ensure consistent fit and function in EV pump systems.
- Thermal Resistance: Withstands continuous operating temperatures from -40°C to +150°C, suitable for both cooling and heating circuits.
- Chemical Resistance: Resistant to glycol-based coolants, oils, and other automotive fluids.
- Custom Design Support: Our engineering team offers DFM (Design for Manufacturing) analysis, mold flow simulation, and prototyping to accelerate your project.

Frequently Asked Questions
-
What is Gröditz GPM58 steel and why is it used?
Gröditz GPM58 is a high-performance tool steel known for excellent wear resistance and dimensional stability. It is used as a reinforcement insert in the plastic parts to provide structural integrity under high stress and temperature. -
Can you provide samples for testing?
Yes, we can provide samples after reviewing your drawings or specifications. Sample lead time is typically 10-15 working days. -
What plastic materials are available for the pump parts?
Common options include PPS (Ryton), PPA, PEEK, and PA66+GF30. We can also recommend materials based on your coolant and temperature requirements. -
Do you support ultrasonic welding design for different frequencies?
Yes, our parts are designed to be compatible with both 20 kHz and 35 kHz ultrasonic welding systems. We can adjust joint geometry as needed. -
What is the minimum order quantity (MOQ)?
For new custom parts, the MOQ is typically 1,000 pieces. For existing standard designs, we can accept smaller quantities upon request. -
How do you ensure the quality of the steel inserts?
We source Gröditz GPM58 only from certified suppliers and perform incoming material inspection including hardness testing and chemical composition analysis. -
