Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner in precision injection molded components. As a specialized manufacturer established in 2017 with a 1,000-3,000 sqm factory and 51-100 skilled employees, we take pride in delivering high-performance PPS-GF40 Insert Injection Pump Impellers that meet the most demanding industrial requirements. Our impellers are engineered under IATF 16949 quality management system, ensuring consistent dimensional accuracy, thermal stability, and chemical resistance. With our Full Mold Protection Service, we safeguard your tooling investment and extend mold life, giving you peace of mind in mass production.
Product Overview
The PPS-GF40 pump impeller is a critical component for injection pumps used in oil extraction, chemical processing, water treatment, and automotive fuel systems. Made from Polyphenylene Sulfide reinforced with 40% glass fiber, it offers exceptional mechanical strength, high temperature resistance (up to 240°C continuous), and excellent resistance to harsh chemicals and hydrolysis. The insert injection molding process ensures a strong bond between the metal insert and the PPS matrix, enabling reliable torque transmission and long service life even under high-pressure conditions.
Key Features & Technical Specifications
- Material: PPS-GF40 (Polyphenylene Sulfide + 40% glass fiber) – UL94 V-0 flammability rating, low moisture absorption.
- Insert Options: Stainless steel, brass, or carbon steel inserts available; custom designs accepted.
- Temperature Range: -20°C to +240°C (continuous), with peaks up to 260°C.
- Pressure Rating: Designed for high-pressure injection pump applications up to 350 bar (depending on impeller geometry).
- Dimensional Tolerance: ±0.05 mm on critical diameters; verified by CMM inspection.
- Surface Finish: Smooth mold surface finish (Ra ≤ 0.8 μm) to minimize fluid friction.
- Certification: IATF 16949 certified production line; material certificates available upon request.
- Mold Protection: Full mold protection service including preventive maintenance, repair, and storage – reduces downtime and extends tool life by up to 30%.

Q: Can you customize the impeller dimensions and insert material?
A: Yes, we offer full customization. Provide your 2D/3D drawing, and we will produce the mold accordingly. Insert materials include stainless steel, brass, or carbon steel. -
Q: How does the Full Mold Protection Service work?
A: After each production run, we inspect and clean the mold, perform preventive maintenance, and store it in a controlled environment. This reduces mold wear and ensures consistent quality for repeat orders. -
Q: Is the IATF 16949 certification applicable to all products?
A: Yes, our entire production line is IATF 16949 certified, ensuring strict process control and quality management. We can provide a certificate upon request. -
Q: What is the typical lead time for a new impeller mold and first samples?
A: Mold fabrication takes approximately 30-45 days, and sample delivery within 10-15 days after mold approval. For existing molds, production lead time is 15-20 working days. -
Q: Do you offer material testing reports?
A: Yes, we can provide material certificates (MIL-SPEC, ASTM, or ISO standard) and mechanical properties test reports for each batch. -
Q: What is the minimum order quantity (MOQ)?
A: For custom molds, MOQ is typically 500 pieces per year. For standard impellers with existing molds, MOQ is 100 pieces per order. -
Q: How do you ensure the impeller is balanced for high-speed rotation?
