Changzhou Hongxinyutai Precision Mold Co., Ltd. (Est. 2017) presents our premium Custom Injection Molded NEV Pump Parts crafted from high-performance PPS+GF30 material. Leveraging our 1,000–3,000 sqm factory with 51–100 skilled employees, we deliver precision components featuring an edge gate cold runner system and a glossy finish that enhances both aesthetics and functional sealing. Our TS16969-certified processes ensure consistent quality for demanding electric vehicle pump applications, making us a trusted partner for global markets.
These parts are engineered to withstand high temperatures, aggressive fluids, and mechanical stress typical in NEV cooling, braking, or battery thermal management systems. The combination of PPS+GF30’s inherent flame retardancy and our precision molding provides dimensional stability over extended service life. The cold runner design minimizes material waste and reduces cycle time, offering cost-effective production without compromising part integrity. Every detail—from the glossy surface that reduces fluid drag to the edge gate placement that prevents flow marks—is optimized for pump performance.
Key Features & Benefits
- High-Performance Material: PPS+GF30 offers excellent thermal resistance (up to 240°C continuous), outstanding chemical resistance to coolants and oils, and high mechanical strength (tensile strength 150–200 MPa). This ensures long-lasting reliability in harsh NEV environments.
- Precision Cold Runner System: The edge gate cold runner design provides precise control over melt flow, reducing flash and sink marks. It also lowers scrap rates compared to hot runner systems, making it an eco-friendly and cost-efficient choice.
- Glossy Surface Finish: Achieves a Ra
- Customization Capabilities: We offer flexible customizations in dimensions (from 10 mm to 500 mm), colors (including RAL codes), and tolerances (typical ±0.05 mm). Mold modifications can be made to integrate inserts, threads, or specific mounting features.
- TS16969 Quality Management: Our production line follows strict TS16969 protocols, ensuring traceability, process control, and defect-free delivery. Each batch undergoes dimensional inspection, material verification, and functional testing.
Technical Specifications (Typical Values)

| Certification | TS16969 |
Our parts are designed to meet strict NEV industry requirements. The PPS+GF30 grade is specifically chosen for its low moisture absorption (0.02%) and excellent dielectric properties, making it ideal for pump components near high-voltage systems. The edge gate cold runner technology ensures even filling for complex geometries, such as scroll housings or impeller vanes, without weld lines that could cause stress points.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum continuous operating temperature for PPS+GF30?
A: PPS+GF30 can withstand continuous use at temperatures up to 240°C, with peak short-term exposure up to 260°C. This makes it suitable for under-the-hood NEV applications. -
Q: Can you match specific colors for the glossy finish?
A: Yes, we can color-match any RAL or Pantone code. The glossy finish is achieved through polished mold surfaces and precise process control, so color consistency is maintained. -
Q: What is the typical lead time for a new mold and first samples?
A: For a standard mold, tooling takes 25–35 working days, with first samples delivered within 5 days after tooling completion. Urgent requests can be expedited (subject to feasibility). -
Q: Do you offer design assistance for pump part optimization?
A: Absolutely. Our engineering team provides DFM (Design for Manufacturability) feedback to improve part performance and reduce mold costs. We can adjust gate locations, wall thickness, and draft angles. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1,000 pieces for custom parts, but smaller quantities are available for prototyping or pre-production validation. We also offer mold-only orders if you prefer to run production elsewhere. -
Q: How do you ensure the surface finish is consistent across large batches?
A: We use advanced mold temperature control (cooling channel optimization) and periodic surface roughness checks. The TS16969 process audits ensure that mold maintenance and injection parameters remain stable. -
Q: Are these pump parts compatible with aggressive coolants like water-glycol mixtures?
A: Yes, PPS+GF30 exhibits excellent resistance to ethylene glycol, propylene glycol, and typical automotive coolants, even at elevated temperatures. No degradation or swelling occurs under normal conditions.
