Changzhou Hongxinyutai Precision Mold Co., Ltd. is a specialized manufacturer dedicated to delivering high-performance injection molds for the automotive and new energy vehicle (NEV) industry. Our Plastic Injection Mold for NEV Electric Water Pump Housing is engineered to meet the rigorous demands of high-temperature PPS (Polyphenylene Sulfide) material, offering exceptional dimensional stability and long service life. With over 6 years of mold manufacturing experience, a factory area of 1,000–3,000 square meters, and a skilled team of 51–100 employees, we ensure every mold is precision-crafted to optimize your production efficiency and product quality.
This mold is specifically designed for the tight-tolerance water pump housing used in new energy vehicles, where reliability under extreme conditions is critical. Our advanced mold design incorporates conformal cooling channels, robust ejection systems, and high-grade steel inserts to withstand the corrosive and high-temperature nature of PPS. The result is a mold that delivers consistent part quality, reduced cycle times, and minimized waste.
Key Features & Technical Specifications
- High-Temperature PPS Compatibility: The mold is built with premium hot-work tool steel (e.g., H13, 718H) and specialized surface treatments to resist thermal fatigue and wear when processing PPS at over 300°C.
- Precision Cavity & Core: CNC-machined and EDM-finished to achieve tolerances within ±0.01mm, ensuring leak-free water pump housing assembly.
- Optimized Cooling System: Conformal cooling channels (optional) reduce cycle time by up to 30% and minimize part warpage, enhancing overall production efficiency.
- Customizable Cavity Count: Available in single, two, or multi-cavity configurations to match your volume requirements, with mold life ranging from 500,000 to 1,000,000 shots.
- TS16969 Certified Quality: Our manufacturing process follows the TS16969 quality management system, ensuring consistent mold performance and traceability.
- Robust Ejection System: Hydraulic or mechanical ejection options are available to handle complex part geometries and undercuts.
