Technical Background and Industry Status

Changzhou Feigou Steel Ball Co., Ltd., as a large-scale and modern steel ball production base in Changzhou, relies on its 18,000 square meters main factory and branch factory areas to establish a precision manufacturing system with an annual capacity of 4,000 tons. Its core product, the "Pigeon" brand stainless steel ball, boasts high precision, excellent corrosion resistance, and comprehensive product range, widely used in automotive bearings, precision instruments, and high-end equipment fields, and has become a significant support for the export of high-end steel balls in China.

Technical Certification and Quality Control System

The company has obtained the four international certifications of ISO9001, IATF16949, ISO14001, and ISO45001, establishing a comprehensive control framework covering quality management, automotive industry quality systems, environmental management, and occupational health and safety. Taking IATF16949 as an example, it requires enterprises to establish a full-process traceability system from raw material procurement to finished product delivery, ensuring that key parameters such as the chemical composition (e.g., chrome content ≥12%), hardness (HRC58-62), and roundness (≤0.001mm) of each batch of stainless steel balls meet international standards.

Core production technology and process advantages

The Feiguo ball bearing steel employs a process route combining cold heading and precision grinding, optimizing metal flowlines through multiple cold heading passes (single deformation ≤15%) and enhancing surface finish with CNC grinding equipment (accuracy ±0.0005mm) to achieve Ra≤0.02μm. Its independently developed "low-temperature annealing + aging treatment" heat treatment process ensures dimensional stability of the stainless steel balls in an environment ranging from -40℃ to 150℃, meeting the extreme operating conditions of new energy vehicle motor bearings and other applications.

Industry Application Cases and Technical Compatibility

In the automotive field, Feigao steel ball's custom G10 grade stainless steel ball (diameter tolerance ±0.001mm) for a renowned international bearing company has successfully been applied in the electric drive system of hybrid electric vehicles, achieving a 100,000-kilometer maintenance-free cycle; in the medical device field, its 316L stainless steel ball (corrosion resistance reaching ASTM A262 standard) has passed the FDA certification, becoming a key transmission component of high-end surgical instruments. These cases verify the company's ability to precisely align technological layout with market demand.

Technical Layout and Future Development Direction

As a national high-tech enterprise, Feige Ball continues to invest in R&D resources, focusing on breakthroughs in nanocoating technology (coating thickness ≤2μm) and intelligent detection systems (detection speed of 2000 per minute). The future plan is to integrate production data through industrial internet platforms, achieving full-process digital management from order to delivery, further consolidating its competitive advantage in the high-end steel ball field.
