Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a trusted manufacturer with over 7 years of expertise in precision injection molding and tooling. Since our establishment in 2017, we have specialized in delivering high-quality, custom-engineered solutions for the automotive industry, particularly for electric vehicle (EV) thermal management systems. Our Precision EV Water Pump Injection Molded Parts – featuring a 1x2 cavity cold runner PPS+GF30 tooling and ultrasonic welding – are designed to meet the rigorous demands of Southeast Asian Tier-1 suppliers. By combining advanced material science, precise mold engineering, and robust assembly technology, we ensure superior performance, dimensional accuracy, and long-term reliability for your EV water pump applications.
Our injection molded parts are produced using a dedicated cold runner system that optimizes material flow and reduces waste, while the PPS+GF30 (Polyphenylene Sulfide with 30% glass fiber) compound provides exceptional thermal resistance, chemical stability, and mechanical strength. The integrated ultrasonic welding process guarantees leak-proof, hermetically sealed joints, which are critical for water pump components operating under high pressure and temperature cycles. Whether you are a Tier-1 supplier in Southeast Asia or a global OEM, our parts are engineered to deliver consistent quality and cost efficiency.
- Precision 1x2 Cavity Cold Runner Tooling – Balanced flow design ensures uniform filling and minimal material waste, reducing cycle time and overall production cost.
- PPS+GF30 Material – Excellent thermal resistance (up to 240°C continuous), chemical resistance to coolants, and high dimensional stability even under moisture.
- Ultrasonic Welding Assembly – Provides strong, vibration-resistant bonds with no additional adhesives or fasteners, achieving leak-tight seals.
- TS16969 Certified Manufacturing – Our quality management system complies with automotive industry standards, ensuring traceability and consistent output.
- Customizable Options – Cavity layout, gate design, and surface finish can be tailored to your specific water pump geometry and performance requirements.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of using PPS+GF30 for EV water pump parts?
A: PPS+GF30 offers excellent thermal and chemical resistance, high dimensional stability, and low moisture absorption, making it ideal for long-term exposure to hot coolant and high-pressure environments in electric vehicle water pumps.
Q2: Can the cold runner tooling be adapted for other cavity configurations?
A: Yes, the 1x2 cavity design is a standard configuration, but we can customize the mold to 1x1, 1x4, or other layouts depending on your production volume and part geometry. Please contact us for feasibility analysis.
Q3: How does ultrasonic welding ensure a leak-proof seal?
A: Ultrasonic welding uses high-frequency vibrations to create frictional heat at the joint interface, melting the PPS material locally. Upon cooling, the bond is as strong as the base material, providing a permanent, leak-proof seal without any additional sealants.
Q4: What is the typical lead time for mold fabrication and first sample delivery?
A: Lead time varies based on complexity, but typically 4–6 weeks for mold fabrication and an additional 2–3 weeks for sample injection and ultrasonic welding validation. We can expedite for urgent projects upon request.
Q5: Do you have any minimum order quantity (MOQ) for these parts?
A: Our MOQ is flexible. For initial samples, we can produce as few as 100–200 pieces. For mass production, we recommend orders of 5,000+ pieces to optimize cost. Contact us for detailed pricing.
Q6: Is the TS16969 certification applicable to the entire production process?
A: Yes, our TS16969 certification covers design, mold manufacturing, injection molding, and assembly processes, ensuring consistent quality and traceability throughout the entire production chain.
Q7: Can you provide design assistance for the water pump housing or impeller?
A: Absolutely. Our engineering team can assist with DFM (Design for Manufacturing) analysis, shrink compensation, and gate placement to optimize your part for injection molding and ultrasonic welding.
Q8: Which markets do you currently serve for EV water pump applications?
A: We supply to Tier-1 suppliers in Southeast Asia, North America, Europe, and other regions. Our export experience ensures compliance with international standards such as TS16969 and customer-specific requirements.
