Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer dedicated to high-precision injection molds for the automotive industry. With a factory size of 1,000–3,000 square meters and a team of 51–100 skilled employees, we have been supplying reliable mold tooling solutions to global clients across North America, Europe, Southeast Asia, and beyond. Our Precision Mold Tooling for NEV Electric Water Pump Automotive Thermal Management System Side Gate is specifically designed to meet the stringent requirements of new energy vehicle thermal management systems. This mold delivers exceptional dimensional accuracy, long service life, and optimized cycle times, making it an ideal choice for producing electric water pump housings with complex geometries.
Key Features & Technical Advantages
- Side Gate Injection Design – Enables precise filling of thin-walled parts, reducing warp and improving cosmetic appearance. The side gate layout allows for balanced material flow and minimizes gate vestige, which is critical for sealing surfaces in water pump applications.
- High-Strength Steel Selection – Core and cavity are made of premium H13 or 8407 steel, hardened and tempered to 48–52 HRC, ensuring resistance to wear, corrosion, and thermal fatigue. The mold base uses S50C steel for stability.
- Advanced Cooling System – Conformal cooling channels or baffle designs are integrated to achieve uniform temperature distribution, reducing cycle time by up to 20% and improving part dimensional stability.
- Precision Machining – All components are machined on 5-axis CNC and EDM equipment with tolerances of ±0.01 mm. Coordinate measuring machines (CMM) are used for 100% inspection of critical dimensions.
- Customizable Options – Hot runner systems (e.g., from YUDO, INCOE) or cold runner designs are available upon request. Mold size, number of cavities, and ejection mechanism can be tailored to your production volume and machine specifications.
- Compliance with TS16969 – Our manufacturing process is certified under TS16969, ensuring consistent quality control and traceability throughout the mold lifecycle.
