At Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017 and operating from a 1,000–3,000 m² facility in Changzhou, Jiangsu, we specialize in delivering precision mold solutions for the automotive industry. As a dedicated manufacturer with 51–100 skilled employees, we are proud to present our Auto Electric Water Pump Plastic Components: Custom 1x2 Cold Runner PPS+GF30 Tooling & Ultrasonic Welding Support — a tailored solution specifically designed for Southeast Asian EV makers. This product combines advanced material engineering, precise mold design, and post-molding assembly support to help you achieve high-performance, reliable water pump components at competitive costs.
Our custom tooling features a 1x2 cold runner system using PPS+GF30 (Polyphenylene Sulfide with 30% glass fiber), a material known for its excellent dimensional stability, chemical resistance, and thermal endurance — ideal for electric water pump housings and impellers. The cold runner design minimizes material waste and reduces cycle time, while the 1x2 cavity layout offers balanced production for medium-volume runs. Additionally, we provide ultrasonic welding support to ensure leak-proof assembly of plastic components, a critical requirement for EV cooling systems.
Key Features & Technical Specifications
- Material: PPS+GF30 — high temperature resistance (up to 260°C), excellent creep resistance, and low moisture absorption.
- Runner System: Cold runner with 1x2 cavity — optimized for efficient material flow and reduced scrap.
- Custom Mold Design: Fully tailored to your water pump geometry, including gate location, cooling channels, and ejection system.
- Ultrasonic Welding Support: We assist in joint design, horn selection, and process parameter optimization to achieve strong, hermetic seals.
- Application: Specifically engineered for electric water pumps used in EV thermal management systems, battery cooling, and motor cooling.
- Quality Assurance: Manufactured under TS16969 certified quality management system, ensuring consistent part quality and traceability.
- Lead Time: Typical mold fabrication: 35–50 days; sample delivery: 7–10 days after mold trial.
| Parameter | Specification |

| Packaging | Standard wooden case or custom export packaging |
Benefits for Your Business
- Cost Efficiency: Cold runner system reduces material waste compared to hot runner, lowering your per-part cost.
- Fast Production: 1x2 cavity layout allows balanced filling and faster cycle times, increasing output.
- Reliable Sealing: Ultrasonic welding support ensures leak-free joints, critical for coolant systems.
- Reduced Development Risk: Our team provides full mold flow analysis (Moldflow) and design for manufacturability (DFM) feedback before cutting steel.
- Scalable Solution: From prototype to mass production, we can adapt the mold design for multi-cavity or family molds as your volume grows.
- Local Support for SE Asia: We regularly ship to Southeast Asian markets via Jiangsu, Shanghai, or Shenzhen ports, with fast logistics and customs clearance assistance.
With over 6 years of experience in precision mold manufacturing, Changzhou Hongxinyutai has served customers across North America, South America, Europe, Asia, and Africa.

Frequently Asked Questions
-
Q: What is the typical lead time for a custom 1x2 cold runner mold?
A: Mold fabrication usually takes 35–50 days from design approval, and sample parts can be delivered within 7–10 days after mold trial. -
Q: Can you provide ultrasonic welding parameter recommendations?
A: Yes, we offer full ultrasonic welding support, including joint design, horn selection, and process parameter optimization, based on your material and part geometry. -
Q: Is PPS+GF30 material suitable for continuous operation at 120°C?
A: Absolutely. PPS+GF30 can withstand continuous use temperatures up to 220°C and short-term peaks up to 260°C, well above typical EV water pump requirements. -
Q: Do you offer mold sampling or small batch production?
A: Yes, we can produce sample shots (typically 50–200 pieces) for your testing, and then scale up to full production runs. -
Q: What certifications do you hold?
A: Our facility is TS16969 certified, ensuring a quality management system tailored for automotive component manufacturing. -
Q: Can you modify an existing mold design to add a cold runner?
A: Yes, we can retrofit or redesign existing molds. Please provide your current mold drawings or samples for evaluation. -
Q: How do you ensure the mold cavity surface finish meets requirements?
A: We use advanced CNC machining, EDM, and polishing techniques. Surface finish can be customized from SPI A2 to SPI D3, depending on your needs.
