NEV Electric Water Pump Housing Injection Molding IATF 16949 PA66 GF30 Hydrolysis Resistant Parts Sweden
Product Spotlights
Changzhou Hongxinyutai Precision Mold Co., Ltd. is a dedicated manufacturer of high-precision injection molded components for the new energy vehicle (NEV) industry. Our NEV Electric Water Pump Housing is molded from PA66 GF30 hydrolysis-resistant material under strict IATF 16949 quality management system, ensuring reliable performance in demanding automotive thermal management systems. Designed for the Swedish market and global NEV platforms, this housing combines lightweight strength with exceptional resistance to hot coolant and long-term hydrolysis.
Key Features & Technical Specifications:
- Material Excellence: Virgin PA66 reinforced with 30% glass fiber, specially formulated with hydrolysis stabilizers to withstand continuous exposure to water-glycol coolant at temperatures up to 130°C.
- Precision Injection Molding: Our state-of-the-art injection molding machines (80–650 ton) ensure tight dimensional tolerances (±0.05mm) and consistent wall thickness for leak-free assembly.
- IATF 16949 Quality System: Fully compliant with automotive industry standards, including PPAP, FMEA, and SPC control plans for zero-defect delivery.
- Customizable Design: We offer ODM/OEM services – from mold design to production – to meet specific flange interfaces, mounting brackets, and connector positions.
- Hydrolysis Resistance Tested: Parts pass 1000+ hours of accelerated aging in 50/50 coolant at 130°C with minimal property loss (tensile strength retention >85%).

Frequently Asked Questions
-
Q: What is the typical lead time for this water pump housing?
A: For existing molds, lead time is 2–3 weeks. For new molds, please allow 4–6 weeks for design, tooling, and sampling. -
Q: Can you provide material certificates for the PA66 GF30?
A: Yes, we supply material certificates (MDS, MSDS, and RoHS/REACH compliance) upon request. Our material is sourced from qualified suppliers. -
Q: Is the housing compatible with standard O-rings?
A: The housing is designed with standard O-ring grooves (e.g., AS568 sizes). We can adjust dimensions to match your specific seal requirements. -
Q: Do you perform any testing before shipment?
A: Yes, 100% of parts undergo dimensional inspection, pressure testing (0.5 MPa air under water), and visual inspection. Sample reports are available. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 500–1000 pieces for existing molds. For new molds, MOQ negotiable based on tooling investment. -
Q: Can you produce parts with a different color?
A: Yes, we can color-match to your specification (e.g., black, blue, green) using masterbatch. Minimum quantity may apply. -
Q: How do you ensure hydrolysis resistance for long-term use?
A: Our material formulation includes special stabilizers, and we validate through accelerated aging tests (1000h at 130°C in coolant). Results are documented.
