Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a trusted manufacturer since 2017, specializing in high-precision injection molds and custom plastic components. Our Precision PPS+GF30 Injection Molding for NEV Pump is engineered to deliver exceptional performance for the demanding new energy vehicle industry. With a 1-cavity design optimized for 300,000 shots and ultrasonic weldability, this product ensures consistent quality, dimensional stability, and reliable assembly in critical pump applications. Leveraging our TS16969-certified facility and 51–100 skilled professionals, we are committed to providing solutions that meet the highest standards of durability and precision.
This molding solution is specifically designed for New Energy Vehicle (NEV) pump components where thermal resistance, chemical stability, and mechanical strength are paramount. The use of PPS (Polyphenylene Sulfide) reinforced with 30% glass fiber (GF30) delivers outstanding performance in high-temperature and corrosive environments, making it ideal for coolant pumps, oil pumps, and other fluid handling systems in electric and hybrid vehicles. The ultrasonic weldable feature simplifies assembly, reduces cycle time, and ensures leak-proof joints.
Key Features & Technical Specifications
- Material: PPS+GF30 – excellent heat resistance (up to 240°C continuous), low moisture absorption, and superior chemical resistance.
- Mold Cavity: Single cavity – designed for high precision and repeatability, ideal for small to medium production runs.
- Mold Life: 300,000 shots – built with hardened tool steel and advanced cooling channels to ensure long service life.
- Welding Compatibility: Ultrasonic weldable – integrated with optimized gate design to facilitate strong, leak-free ultrasonic joints.
- Precision Tolerances: Maintains dimensional accuracy within ±0.05 mm, critical for pump housing and impeller geometries.
- Surface Finish: SPI-A2 or custom texture available upon request, reducing friction and improving fluid dynamics.
- Production Scalability: While designed for 1 cavity, molds can be adapted for multi-cavity configurations (customizable).

Advantages & Customer Benefits
- Enhanced Reliability: PPS+GF30 resists thermal cycling, coolant chemicals, and hydrolysis, reducing pump failure risk in NEVs.
- Cost-Effective Production: The 1-cavity mold with 300K-shot life offers a low-cost entry for prototype or low-volume validation, while the durable steel ensures long-term value.
- Simplified Assembly: Ultrasonic weldability eliminates the need for adhesives or mechanical fasteners, lowering assembly costs and improving production speed.
- Consistent Quality: Our TS16969 certification (automotive standard) ensures rigorous process control, from raw material to final inspection.
- Customization Available: We can adjust gate location, cooling design, and surface finish to meet specific pump design requirements.
- Global Logistics: Shipped from Jiangsu, Shanghai, or Shenzhen ports, serving markets across North America, Europe, Asia, and more.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this mold?
A: Standard lead time is 4–6 weeks for design, fabrication, and trial shots. Expedited options are available upon request. -
Q: Can this mold be used for other materials besides PPS+GF30?
A: Yes, the mold design can be adapted for other high-temperature thermoplastics like PEEK, LCP, or PA6T. However, material-specific adjustments may be required. -
Q: Is the mold tested before shipment?
A: Absolutely. We conduct a full mold trial and provide sample parts for approval. We also offer optional mold validation reports. -
Q: What is the warranty period for the mold?
A: We offer a 12-month warranty against defects in materials and workmanship, covering normal production conditions. -
Q: Do you provide support for the ultrasonic welding process?
A: Yes, we can recommend optimal welding parameters (e.g., amplitude, pressure, time) based on part geometry and material. We also collaborate with ultrasonic equipment suppliers. -
Q: Can you produce multi-cavity molds for higher volume?
A: Yes, we offer scalable solutions. For higher production volumes, we can design and manufacture 2-cavity, 4-cavity, or more, depending on your requirements. -
Q: What file formats do you accept for mold design?
A: We accept STEP, IGES, STL, and native CAD formats (SolidWorks, UG/NX, Pro/E). 3D scanning services are also available. -
Q: How do you ensure the surface finish meets the pump's fluid dynamics needs?
A: We use EDM polishing and texturing techniques to achieve SPI finishes from A2 to D3. We can also match specific roughness (Ra) values per your specifications.
