Changzhou Hongxinyutai Precision Mold Co., Ltd. specializes in designing and manufacturing high-precision injection mold tooling for automotive and industrial applications. Since 2017, we have been dedicated to delivering reliable, cost-effective molds that meet the unique demands of new energy vehicles (NEV). Our PPS+GF30 Plastic Injection Mold Tooling for NEV Water Pump features a side gate cold runner system and is capable of achieving a wall thickness as low as 1.5mm, ensuring lightweight, durable components.
This mold is engineered to process PPS (Polyphenylene Sulfide) reinforced with 30% glass fiber, a high-performance thermoplastic known for its excellent thermal stability, chemical resistance, and dimensional stability. The side gate design minimizes material waste and ensures uniform filling, while the cold runner system simplifies maintenance and reduces cycle time. Ideal for producing water pump housings and impellers for electric vehicles, this tooling solution offers superior precision and long service life.
Key Features & Technical Specifications
- Material Compatibility: Optimized for PPS+GF30, with excellent flow and cavity filling properties.
- Gate & Runner System: Side gate with cold runner – reduces material waste and simplifies color/material changes.
- Wall Thickness Capability: Achieves 1.5mm thin walls without compromising strength, enabling lightweight pump designs.
- Mold Construction: High-quality hardened steel (customizable) with precision machining for tight tolerances.

Why Choose Our Mold for NEV Water Pump Production? The combination of PPS+GF30 material and our side gate cold runner design delivers consistent part quality with minimal flash. The 1.5mm wall thickness capability is especially critical for reducing weight in electric vehicle components, improving energy efficiency without sacrificing mechanical properties. Our molds are built with advanced CNC machining and EDM technologies, ensuring tight tolerances down to ±0.01mm.
With a dedicated team of 51-100 skilled employees and a factory spanning 1,000-3,000 square meters, we provide full turnkey solutions from design to mold trial. We have exported to various markets including North America, Europe, Southeast Asia, and the Middle East, reflecting our commitment to global quality standards. Our TS16969 certification further guarantees that every mold meets stringent automotive industry requirements.
Trust & Reliability: Since 2017, we have completed hundreds of successful mold projects for NEV components. Our customers benefit from competitive pricing, on-time delivery (via Jiangsu, Shanghai, or Shenzhen ports), and responsive after-sales support. We invite you to discuss your specific water pump mold requirements – our engineers will provide a tailored solution that maximizes your production efficiency.
Frequently Asked Questions (FAQ)
- Q: What materials are compatible with this mold besides PPS+GF30? A: While optimized for PPS+GF30, the mold can be adapted for other high-temperature engineering plastics such as PEEK, LCP, or PA66+GF after consultation with our engineering team.
- Q: What is the typical lead time for this mold? A: Standard lead time is 30-45 working days, depending on complexity and cavity number. Rush orders are available upon request.
- Q: Can the mold be designed for a hot runner system instead of cold runner? A: Yes, we can offer a hot runner version as an option. However, the cold runner design is recommended for cost-effectiveness and easier maintenance in PPS+GF30 applications.
- Q: How does the side gate affect the part appearance? A: The side gate leaves a small witness mark on the edge of the part, which is acceptable for most water pump components. If gate-vestige-free appearance is required, we can suggest a sub-gate or tunnel gate alternative.
- Q: What is the maximum cavity number you can offer for this mold? A: We can design molds with up to 8 cavities for small water pump parts. For larger housings, 1-2 cavities are typical to ensure uniform cooling and part quality.
- Q: Does the mold come with a trial and validation report? A: Yes, we provide full mold trial records, including dimensional inspection report, process parameters, and sample parts for your approval before shipment.
- Q: What maintenance is required for this cold runner mold? A: Regular cleaning of the runner and gate area, periodic inspection of cooling channels, and replacement of wear parts (e.g., ejector pins) after every 200,000 cycles are recommended.
- Q: Can you customize the mold for different injection molding machines? A: Absolutely. We can adapt the mold base, locating ring, and nozzle radius to fit your specific machine (e.g., Haitian, Engel, Arburg).
