Changzhou Feige Steel Ball Co., Ltd.
Technical Background and Industry Position
Changzhou Feiguo Steel Ball Co., Ltd., as a scaled and modern steel ball production base in Changzhou, boasts an independent main factory and branch factory covering 18,000 square meters, and has a hard power of an annual production capacity of 4,000 tons, firmly ranking in the first echelon of domestic steel ball production. The company focuses on the development and export of high-end steel balls of all categories with the "Pigeon" brand at its core, and its products cover multiple fields such as precision bearings, automotive parts, and industrial machinery, becoming a technologically competitive producer with strong competitiveness in both domestic and international markets.

Technical Certification and Quality Control System
Feige steel balls have passed four international certifications: ISO9001 Quality Management System, IATF16949 Automotive Industry Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System. This ensures full-process quality control from raw material procurement to finished product delivery. For instance, the stainless steel ball production uses high-precision cold-forging technology, with the ball roundness error controlled within ±0.001mm and surface roughness Ra≤0.01μm, meeting the stringent precision requirements of high-end bearings.
Core Technology and Production Capacity Analysis
The company's technical layout covers three major fields: material research and development, heat treatment technology, and surface treatment.
1. Material Research and DevelopmentCollaborating with domestic universities to develop low-oxygen stainless steel materials, reducing the oxygen content in spheres from the conventional 15ppm to below 5ppm, significantly improves fatigue resistance and extends service life by over 30%.
2. Heat treatment processUsing vacuum quenching technology, the ball hardness uniformity reaches HRC60-64 with precise control of quenching temperature (850-900℃) and holding time (2-4 hours), with hardness difference ≤1HRC.
3. Surface TreatmentSelf-developed ultra-fine grinding technology combined with alumina polishing liquid, achieving defect-free and oxide-free surface of spheres, meeting the hygiene standards for food-grade stainless steel balls.

Typical Application Case: Automotive Bearing Steel Ball Export Project
In an order from a renowned international automotive parts supplier, Feige Steel Ball supplies 8mm diameter G10 grade stainless steel balls for new energy vehicle drive motor bearings. The project requires batch consistency of the spheres to be ≤0.5μm, and they must pass extreme temperature cycle tests from -40℃ to 150℃. By optimizing material ratios and heat treatment parameters, Feige Steel Ball achieved a final product pass rate of 99.97%, helping the customer reduce overall costs by 15% and successfully enter the high-end European market.
Technical Advantages and Industry Application Scenarios
Feiyue Steel Balls' technical advantages are reflected in three aspects: Firstly, comprehensive category coverage, capable of producing various steel balls with diameters ranging from 0.5mm to 50.8mm; secondly, customized services, supporting adjustments of parameters such as hardness, accuracy, and corrosion resistance as required; thirdly, rapid response capability, relying on modern production lines, shortening the delivery cycle of regular orders to 7 days. Its products are widely used in precision instruments, aerospace, medical equipment, and other fields, becoming an important link in the domestic high-end manufacturing industry chain.
