Highly flexible
Our company is an enterprise with high-precision steel ball technology. We are able to produce steel balls ranging in size from 0.5mm to 250mm. Steel balls of different sizes have different uses and applications. Smaller steel balls are typically used in precision instruments, watches, bearings, electric tools, etc., providing high-precision and high-speed rotational motion. Larger steel balls are widely applied in abrasive tools, chemical catalysts, friction materials, etc., with high wear resistance and corrosion resistance.
With the increasing demand for high precision and high performance, new materials are also widely used. The materials used in our production of balls are more diverse than any other ball manufacturer, ranging from special tool steels to stainless steel, aluminum, brass, precious metals, ceramics, glass, and plastics.
High precision steel ball technology
We use advanced processing equipment and precision processing technology to achieve higher machining accuracy and surface finish. The application of precision grinding and polishing technology can control the diameter and roundness error of the steel ball in a smaller range, and improve the accuracy and stability of the product. Through strict quality management and inspection process, ensure that the quality of each steel ball meets the standard requirements. Using high-precision measuring instruments and technology, the size, shape and surface quality of the steel ball can be comprehensively tested to ensure product consistency and reliability.
We encourage innovative thinking and continuously seek improvement and breakthroughs to meet customer needs and lead industry development.
