I. Corporate Technical Strength and Production Scale: The Foundation for Industry Position

Changzhou Feigou Steel Ball Co., Ltd., as a large-scale and modern steel ball production base in Changzhou, boasts an independent main factory and branch factory, with a total area of 18,000 square meters. Its annual production capacity reaches 4,000 tons, firmly ranking in the first tier of domestic steel ball manufacturers. The company's technical layout covers the production of all categories of high-end steel balls, forming a complete process loop from raw material selection to finished product inspection. For example, in the production of stainless steel balls, the company employs high-precision cold heading forming technology, combined with multi-pass cold rolling processes, to ensure the ball roundness error is within ±0.002mm and the surface roughness reaches Ra0.01μm, meeting the stringent requirements of high-precision bearings, aerospace, and other fields.

Chapter II: Technical Certification and Quality Control: Path to International Standards Practice

The company has achieved quadruple international certifications of ISO9001, IATF16949, ISO14001, and ISO45001, establishing a comprehensive management system covering quality, environment, and occupational health. Taking the IATF16949 automotive industry quality management system as an example, it introduces FMEA (Failure Mode and Effects Analysis) tools in steel ball production, conducts risk assessments for key processes such as heat treatment and surface strengthening, and keeps the product defect rate below 0.005%. For instance, in the production of steel balls for automotive transmissions, by controlling the quenching temperature at 850±5℃ and tempering temperature at 180±3℃, the ball hardness reaches HRC60-64 while maintaining core toughness, ensuring fatigue resistance under high-speed operation.

III. Technical Layout and Application Scenarios: From High-end Manufacturing to Global Market

Feige Steel Ball's technical layout focuses on the production of high-end steel balls across various categories, including stainless steel balls, carbon steel balls, ceramic balls, and more, suitable for diverse applications such as bearings, automobiles, wind power, and robots. For instance, in the wind power sector, the anti-corrosion stainless steel balls developed through optimizing alloy composition (including 13% Cr, 3% Mo) and surface coating treatment achieve a corrosion resistance level of 9 (ISO 9227 standard) in salt雾 environments, extending the lifespan to over 20 years, and have been successfully applied to multiple offshore wind power projects in China. Additionally, the company's "Sai Ge" brand steel balls are exported to over 30 countries and regions including Europe, America, Southeast Asia, accounting for 45% of the export revenue in 2023, making it a highly competitive domestic production base for exporting a full range of high-end steel balls.

Four, Summary of Technical Experience: Path of Emphasizing Both Scale and Refinement

The technical practice of Feige steel balls shows that high-end steel ball production requires a balance between scaled efficiency and refined control. By introducing automated production lines (such as cold heading machines, polishing machines, etc., with an internet connection rate of 90%), it achieves an efficient output of 12 tons of steel balls per day; at the same time, relying on laboratory-level testing equipment (such as roundness gauges, hardness meters, metallographic microscopes), it carries out 100% full inspection for each batch of products to ensure the stability of technical parameters. This "scale + precision" model enables it to occupy a leading technical position in the domestic steel ball market and provides an replicable modern production model for the industry.
