Part 1: Company's Technical Layout and Production Scale

Changzhou Feigou Steel Ball Co., Ltd., as a national high-tech enterprise, relies on its 18,000 square meters of independent main factory and branch factory areas to establish a full-process production line covering raw material inspection, precision processing, and surface treatment. Its annual production capacity reaches 4,000 tons, with products ranging from G5 to G1000 precision stainless steel balls in diameters from 0.5mm to 50.8mm, suitable for various applications such as bearings, automobiles, aerospace, etc. The company has passed the quadruple certification of ISO9001 Quality Management System, IATF16949 Automotive Industry Quality Standard, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System, ensuring that the production process complies with international standards.

Chapter 2: Core Technology Analysis: Precision Control from Materials to Finished Products

1. Material Selection and Pretreatment304, 316L food-grade stainless steel is used, with element content tested by spectrometer to ensure material hardness (HRC58-62) and corrosion resistance meet standards. The pretreatment stage employs ultrasonic cleaning to remove oil stains, with particle size control ≤5μm.

2. Cold heading technologyUsing a six-station high-speed cold heading machine, wire material is cold挤压 into spherical blanks, with each blank forming time ≤0.3 seconds, and size tolerance controlled within ±0.005mm.

3. Polishing and strengthening processSurface roughness is achieved through rough grinding on a three-roll polishing machine, followed by treatment on a high-precision grinder (accuracy of 0.001mm), and finally strengthened with a vibratory polishing machine. The surface roughness Ra is ≤0.01μm, and the hardness is increased by 15%-20%.

3. Industry Application Cases: Technical Implementation in High-End Markets

1. Automotive fieldSupply G10 grade stainless steel balls for an international car brand, used in transmission bearings, with a temperature range of -40℃ to 150℃, and a lifespan of up to 2 million cycles without failure.

2. Medical Device316L stainless steel balls are FDA-certified for orthopedic implants, with a smooth surface finish meeting sterile requirements, annual supply exceeds 5 million pieces.

3. AerospaceCustom-made G5 ultra-precision spheres for satellite gyroscope, roundness error ≤0.05μm, maintaining stable performance in a vacuum environment.

4. Technical Advantages and Industry Compatibility

The technical advantages of Feiguo Steel Balls are reflected in three aspects: Firstly, full-process digital control through MES systems for real-time monitoring of production data; secondly, flexible production lines that can quickly switch between different specifications of products; and thirdly, customized service capabilities supporting the research and development and production of non-standard spheres. The company's products have been exported to over 30 countries, continuously increasing their market share in the high-end market, and have become a benchmark enterprise for technological upgrading in the domestic steel ball industry.
