Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a professional manufacturer specializing in precision plastic components for automotive systems. Our Auto Electric Water Pump Plastic Components made of PPS+GF30 (Polyphenylene Sulfide with 30% glass fiber) are designed for demanding under-hood environments. These components feature ultrasonic welded assembly and a smooth surface finish, ensuring leak-proof performance and efficient fluid flow. The model Gröditz GPM58 is engineered for long service life, rated at 300,000 shots (cycles), making it an ideal choice for OEM and aftermarket water pump applications.
Our manufacturing facility spans 1,000–3,000 square meters and is equipped with advanced injection molding machines and ultrasonic welding stations. We strictly follow automotive quality management systems, and our products are certified to TS16969 standards (available upon request). With a team of 51–100 skilled employees, we deliver consistent quality and on-time delivery to global markets including North America, Europe, Southeast Asia, and the Middle East.
Key Product Features & Technical Specifications
- Material Excellence: PPS+GF30 provides outstanding thermal stability (up to 240°C continuous), excellent chemical resistance to coolants and oils, and dimensional stability under high pressure.
- Ultrasonic Welding: All joints are ultrasonically welded to create a strong, homogeneous bond without adhesives or fasteners, ensuring zero leakage over the product's life.
- Smooth Surface: Precision mold polishing and optimized injection parameters result in a smooth surface finish (Ra ≤ 0.8 μm), which reduces fluid friction and improves pump efficiency.
- High Durability: Rated for 300,000 operational cycles (shots), the component withstands repeated thermal and mechanical stress typical in electric water pump systems.
- Model Compatibility: Designed as a direct replacement for Gröditz GPM58 series water pumps, with exact dimensions per customer specifications.
- Lightweight Construction: Plastic components reduce overall pump weight by up to 40% compared to metal alternatives, contributing to vehicle fuel efficiency.
