Changzhou Hongxinyutai Precision Mold Co., Ltd. (established in 2017) is a specialized manufacturer of precision injection molds and molded parts. With a factory spanning 1,000–3,000 square meters and a team of 51–100 skilled employees, we are proud to present our Auto EV Water Pump Injection Molded Parts – a high-performance solution designed for the rigorous demands of electric vehicle thermal management. These parts are manufactured using PPS+GF30 (30% glass fiber reinforced polyphenylene sulfide) and are produced under IATF 16949 quality management system, ensuring consistent quality and reliability for Southeast Asian buyers and global markets.
Our product combines custom tooling expertise with robotic arm mass production capabilities, offering you a turnkey solution from mold design to high-volume output. Whether you need a specific geometry or tight tolerance, our team delivers precision parts that meet the exact specifications of your EV water pump system. The material PPS+GF30 provides excellent chemical resistance, dimensional stability, and high-temperature performance – ideal for the coolant environment in electric vehicles.
We serve clients across North America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, the Middle East, East Asia, Western Europe, Central America, Northern Europe, Southern Europe, South Asia, and the domestic Chinese market. Our commitment to quality and on-time delivery makes us a trusted partner for automotive OEMs and tier-1 suppliers.
Key Features & Technical Specifications
- Material Advantage: PPS+GF30 offers superior heat resistance (continuous use up to 220°C), excellent chemical resistance against coolants and oils, low moisture absorption, and high mechanical strength.
- IATF 16949 Certified: Our production processes are fully compliant with the automotive industry's strict quality standard, ensuring traceability, process control, and continuous improvement.
- Custom Tooling: We design and manufacture molds tailored to your specific water pump geometry, with options for hot runner systems, multi-cavity layouts, and optimized cooling channels.
- Robotic Arm Mass Production: Automated pick-and-place, insert loading, and post-processing operations reduce cycle time and human error, enabling consistent quality at high volumes (up to 500,000 parts per year per mold).
- Precision & Tolerances: Our injection molding process achieves tight tolerances (typically ±0.02 mm on critical dimensions) and excellent surface finish (Ra 0.4–0.8 μm as required).
- Full Process Support: From DFM (Design for Manufacturability) analysis to mold trial, production, and final inspection, we provide end-to-end service.

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ) for these injection molded parts?
A: The MOQ depends on the mold complexity and part size. Typically, for custom tooling, we require a minimum of 10,000–20,000 parts per year to amortize the mold investment. For existing molds, lower MOQs are negotiable. -
Q: Can you provide samples before mass production?
A: Yes, we offer T0 (first-off) samples after mold trial. We can also produce pre-production samples for functional testing. Sample lead time is usually 20–30 days after mold completion. -
Q: What certifications do you hold? Is the IATF 16949 valid for the entire production?
A: Our company holds IATF 16949 certification, which covers all injection molding processes for automotive parts, including design, tooling, production, and delivery. The certification is valid and regularly audited. -
Q: How do you ensure the quality of PPS+GF30 parts?
A: We perform in-process inspections (dimensional checks, visual inspection) and final quality control using CMM, projectors, and tensile testing. We also provide material certificates from our suppliers. Each batch is traceable. -
Q: Can you handle complex geometries or tight tolerances?
A: Absolutely. Our experienced mold designers use Moldflow analysis to optimize filling and cooling. We can achieve tolerances as tight as ±0.01 mm on critical features, and we specialize in complex water pump impeller and housing designs. -
Q: What is the typical lead time for a new project?
A: From mold design to delivery of the first parts, it typically takes 35–50 days. This includes 10 days for design/DFM, 20 days for mold manufacturing, and 5–10 days for sampling and adjustments. Mass production lead time is 15–30 days after sample approval. -
Q: Do you offer any warranties or guarantees?
A: Yes, we provide a 12-month warranty against manufacturing defects on the mold and a 6-month warranty on the molded parts (under normal use). We also offer after-sales technical support via email or video call. -
Q: Are your products RoHS and REACH compliant?
A: The PPS+GF30 material we use can be sourced with RoHS, REACH, and UL94 V-0 certifications upon request. Please inform us of your specific compliance requirements, and we will adjust the material grade accordingly.
