Changzhou Hongxinyutai Precision Mold Co., Ltd. has been dedicated to delivering high-performance tooling solutions since 2017. Our Precision NEV Electric Water Pump Tooling is specifically engineered for the demanding requirements of new energy vehicle (NEV) cooling systems. This mold is manufactured using PPS+GF40 material, offering exceptional thermal stability, chemical resistance, and dimensional accuracy. It is fully compatible with ultrasonic welding processes, ensuring seamless assembly of water pump components. Each mold undergoes rigorous CMM (Coordinate Measuring Machine) verification to guarantee micron-level precision, making it an ideal choice for manufacturers in Southeast Asia seeking reliable, high-quality injection molding tooling.
Our tooling solution is designed to meet the growing demand for efficient electric water pumps in NEVs. The PPS+GF40 (40% glass fiber reinforced polyphenylene sulfide) compound provides outstanding mechanical strength and creep resistance at elevated temperatures, which is critical for the continuous operation of water pumps. The mold’s ultrasonic welding compatibility means that the molded parts can be directly joined using ultrasonic energy without additional surface preparation, reducing production cycle time and assembly costs. With CMM verification, every critical dimension is inspected and documented, ensuring repeatable quality and interchangeability of parts.
Product Features & Technical Specifications
- Material: Premium PPS+GF40 – high heat deflection temperature (over 260°C), excellent flame retardancy, and low moisture absorption.
- Precision: Achieves tolerances within ±0.01 mm, verified by advanced CMM equipment.
- Ultrasonic Welding Compatibility: Mold design incorporates optimized gate and runner systems to produce parts with consistent weld line strength and minimal flash.
- Durability: Hardened tool steel inserts and PPS+GF40 cavity surfaces resist wear and corrosion, extending mold life.
- Cooling System: Conformal cooling channels ensure uniform temperature distribution, reducing cycle time by up to 20%.
- Verification Report: Each mold is supplied with a detailed CMM inspection report, including dimension, flatness, and position tolerances.
- Customization: Available for customer-specific design modifications, including hot runner systems, slide actions, and multi-cavity configurations.

The mold is designed to produce electric water pump components such as housings, impellers, and connectors. The use of PPS+GF40 ensures that the finished parts can withstand continuous exposure to coolant fluids and high temperatures up to 150°C, which is essential for NEV thermal management. The ultrasonic welding compatibility is achieved through precise control of the part geometry, especially the weld joint design, which is validated during the mold trial phase. Our engineering team works closely with clients to adjust the mold design to their specific ultrasonic welding parameters, ensuring strong and hermetic bonds.
