As a professional manufacturer with over 7 years of experience in precision mold and component production, Changzhou Hongxinyutai Precision Mold Co., Ltd. introduces this Precision Auto Coolant Pump Housing crafted from high-performance PPA GF35 material. Designed in Japan and manufactured under strict IATF 16949 standards, this component delivers exceptional burst pressure resistance and dimensional accuracy, making it ideal for demanding automotive cooling systems. Our factory, spanning 1,000-3,000 square meters and staffed by 51-100 skilled workers, ensures every part meets the highest quality requirements.
This coolant pump housing is engineered to withstand extreme operating conditions, providing reliable performance in engine cooling, battery thermal management, and HVAC systems. The use of PPA GF35 (a high-temperature polyphthalamide reinforced with 35% glass fiber) offers superior mechanical strength, chemical resistance, and thermal stability compared to standard materials. Combined with precision injection molding and rigorous quality control, our housing guarantees a tight seal, consistent flow, and long service life.
Key Features & Technical Specifications
- Material: PPA GF35 – excellent heat deflection temperature (up to 280°C), low moisture absorption, and high stiffness.
- Burst Pressure: Exceeds 150 bar, ensuring safety under high-pressure coolant circulation.
- Dimensional Accuracy: Tolerances as tight as ±0.05 mm, achieved through advanced mold design and CNC machining.
- Surface Finish: Smooth, flash-free surface with minimal warpage, thanks to optimized gate and cooling channel design.
- Chemical Resistance: Resistant to coolants, oils, and common automotive fluids, preventing degradation over time.
- Weight Reduction: Approximately 30% lighter than aluminum counterparts, reducing overall vehicle weight.
- Certification: Manufactured under IATF 16949 quality management system (TS16969 also available).
- Custom Options: Available in various colors, thread types, and connector configurations upon request.
