The small balls can be further geometrical designed by additional processes. The focus to the micro and nano subject has lead to the cooperation with various international development and research institutes. A positive example for the mutual cooperation with research institutes is the new process technology for the production of small steel balls. The application field for small balls includes computers, mobile phone lithium battery, REM and mass products like the writing instruments. small steel balls can widely using in computer DVD/CD-ROM hardware and mobile phone lithium battery.
