Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our Precision Auto EV Water Pump Plastic Components, engineered for reliability and performance in the fast-growing electric vehicle market. With over 7 years of manufacturing expertise and a dedicated team of 51–100 skilled professionals, we specialize in producing heavy-duty components using Gröditz GPM58 tooling and PPS+GF30 material. Every part is verified by CMM (Coordinate Measuring Machine) to ensure micron-level accuracy, making our products ideal for demanding Southeast Asian automotive applications.
Our factory, spanning 1,000–3,000 square meters, is equipped with advanced injection molding machines and precision tooling capabilities. We strictly adhere to the TS16969 quality management system, which governs every step from raw material sourcing to final inspection. The combination of Gröditz GPM58 tool steel (known for its high wear resistance and dimensional stability) and PPS+GF30 (30% glass fiber reinforced polyphenylene sulfide) results in components that withstand high temperatures, aggressive coolants, and continuous mechanical stress – exactly what modern EV water pumps demand.
Below we outline the key features, technical specifications, and benefits of our product, followed by a detailed FAQ section.
Key Features & Technical Specifications
- Material Excellence: PPS+GF30 offers exceptional chemical resistance, low moisture absorption, and dimensional stability up to 240°C (continuous service). The glass fiber reinforcement provides high tensile strength and rigidity, reducing warpage and creep under load.
- Premium Tooling: Gröditz GPM58 is a high-performance tool steel with excellent toughness and wear resistance, ensuring long tool life (typically 500,000+ shots) and consistent part quality over large production runs.
- Dimensional Accuracy: Every production batch undergoes 100% CMM inspection. Our CMM verification ensures tolerances as tight as ±0.02 mm, meeting the strict requirements of EV water pump assemblies.
- Heavy-Duty Design: Components are designed to handle continuous operation in high-pressure and high-temperature coolant environments, with reinforced ribs and optimized wall thickness for impact resistance.
- TS16969 Certified Process: From mold design to part delivery, all processes comply with automotive industry standards, including PPAP (Production Part Approval Process) and FMEA (Failure Mode and Effects Analysis).
- Customizable for SE Asian Markets: We offer tailored solutions for voltage, mounting, and connector specifications commonly used in Southeast Asia (e.g., 12V/24V systems, JIS or DIN standards).
| Parameter | Specification |
|---|---|
| Material | PPS (Polyphenylene Sulfide) + 30% Glass Fiber |
| Tool Steel Grade | Gröditz GPM58 (equivalent to 1.2379 / D2) |
| Inspection Method | CMM (Coordinate Measuring Machine) – 100% critical dimensions |
| Typical Tolerance | ±0.02 mm (on dimensions up to 100 mm) |
| Operating Temperature Range | -40°C to +240°C (continuous) |
| Production Capacity | Up to 50,000 parts per month per mold (customizable) |
| Certification | TS16969 (IATF 16949 equivalent) |
Advantages & Customer Benefits
- Longer Service Life: PPS+GF30 resists hydrolysis and corrosion from modern coolants (e.g., ethylene glycol, water-based), reducing the risk of cracking or swelling. Combined with GPM58 tooling, the mold maintains its geometry for millions of cycles, ensuring consistent part quality.
- Reduced Assembly Issues: CMM-verified dimensions guarantee that every component fits seamlessly into the water pump housing, minimizing rework and scrap during assembly.
- Cost-Effective for High Volumes: Our heavy-duty tooling and optimized cycle times (typically 30–45 seconds) lower per-part costs for large-scale production, ideal for EV manufacturers expanding in SE Asia.
- Compliance with Automotive Standards: TS16969 certification means we follow rigorous quality control procedures, including statistical process control (SPC) and traceability. This simplifies your supplier audits and reduces risk.
- Quick Turnaround for Prototypes: We offer rapid prototyping (3–5 days) using the same GPM58 tool steel to validate part design before mass production, accelerating your time-to-market.

Frequently Asked Questions (FAQ)
-
Q: What makes PPS+GF30 better than other plastics like PA66 or PBT for EV water pumps?
A: PPS+GF30 offers superior thermal stability (up to 240°C) and excellent chemical resistance to coolants, outperforming PA66 and PBT in long-term hot water immersion. It also has lower moisture absorption, ensuring dimensional stability in humid environments common in Southeast Asia. -
Q: How does your CMM verification ensure quality?
A: We use a Zeiss CMM with 0.5 μm accuracy to measure all critical dimensions (bore diameters, flatness, perpendicularity) on a sampling plan based on AQL 0.65. For high-volume orders, we offer 100% inspection upon request. Each report is traceable to the production batch. -
Q: Can you customize the tooling for different water pump designs?
A: Absolutely. Our in-house mold design team can modify cavities, gates, and cooling channels to match your specific geometry. We provide DFM (Design for Manufacturability) feedback to optimize part quality and cycle time. -
Q: What is the typical lead time for first samples and mass production?
A: For standard designs, first samples are available within 15–20 days after tooling completion. Mass production lead time is 3–4 weeks for 10,000–50,000 parts. Expedited options are available for urgent orders. -
Q: Do you have experience with TS16969 or IATF 16949? Can you provide PPAP documents?
A: Yes, our process is certified under TS16969 (equivalent to IATF 16949). We can provide PPAP Level 3 documentation including control plan, FMEA, MSA, and capability studies upon request. -
Q: How do you ensure the tool steel Gröditz GPM58 performs well in high-volume production?
A: GPM58 is a Cr-Mo-V alloyed tool steel with high hardness (58–62 HRC) and excellent wear resistance. We perform heat treatment under vacuum with controlled cryogenic treatment to minimize distortion. Regular maintenance and re-coating (e.g., TiN) extend tool life beyond 1 million shots. -
Q: What are the minimum order quantities (MOQ) for new customers?
A: Our MOQ for initial orders is 5,000 parts per design. For repeat orders, we can accommodate lower quantities. We also offer sample orders (10–50 pieces) for testing and qualification. -
Q: Do you provide any warranty or after-sales support?
A: We offer a 12-month warranty against manufacturing defects from the date of shipment. Our technical support team is available via email or video call to assist with installation, troubleshooting, and design improvements.
