As a dedicated manufacturer of precision injection molds and molded parts, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our Plastic Injection Molded Water Pump Parts for NEV, engineered with advanced PPS+GF30 material and precision Gröditz GPM58 mold steel. Established in 2017 with a 1,000–3,000 sqm factory and 51–100 skilled employees, we specialize in delivering high-performance components that meet the demanding requirements of new energy vehicle thermal management systems. Our water pump parts are designed to withstand extreme temperatures, corrosive fluids, and high-pressure cycles, ensuring long-term reliability in electric and hybrid vehicles.
These components are manufactured using state-of-the-art injection molding technology, achieving a mold life of 300,000 shots without compromising dimensional accuracy. The material choice of PPS+GF30 (Polyphenylene Sulfide with 30% glass fiber) provides excellent mechanical strength, thermal stability (up to 220°C), and chemical resistance to coolants and antifreeze. The use of Gröditz GPM58 mold steel ensures superior wear resistance and surface finish, directly translating into consistent part quality over prolonged production runs. Additionally, our parts are ultrasonic welding compatible, enabling seamless integration into complex water pump assemblies.

Frequently Asked Questions
-
Q1: What is the maximum operating temperature for these parts?
A: PPS+GF30 can continuously withstand temperatures up to 220°C, with short-term peaks up to 260°C, making it suitable for electric vehicle cooling systems. -
Q2: Can you customize the part geometry or add metal inserts?
A: Yes, we offer full customization. We can modify dimensions, add threaded inserts, or integrate sealing features per your design. -
Q3: What is the typical lead time for a new mold and first samples?
A: Lead time depends on complexity. For a standard water pump part, mold fabrication takes 25–35 days, and sample delivery within 40 days after tooling approval. -
Q4: Are these parts resistant to long-term coolant exposure?
A: Yes, PPS+GF30 is highly resistant to ethylene glycol and other common coolants, with minimal swelling or degradation over extended periods. -
Q5: Do you provide any quality reports or certifications with each shipment?
A: Absolutely. We provide material certificates, dimensional inspection reports, and an IATF 16949 certificate upon request. -
Q6: What is the minimum order quantity (MOQ)?
A: For standard parts, MOQ is 10,000 pieces. For customized parts, MOQ is negotiable depending on mold investment and part size. -
Q7: Can these parts be used in other automotive fluid systems besides water pumps?
A: Yes, the material and precision make them suitable for oil pumps, coolant valves, and other fluid handling components in NEV and traditional vehicles. -
Q8: How do you ensure the ultrasonic welding compatibility?
A: We design the part geometry with energy directors and maintain tight tolerances on mating surfaces. Our parts are tested with standard ultrasonic welding equipment to ensure strong, leak-free joints.
