In June 2015, the company initiated UL/CUL, TUV, and RoHS certification processes for its products. As of November 25, all certifications have been successfully completed. Notably, every product passed the certification on the first attempt, fully demonstrating the exceptional quality of Quanning's frequency converter-specific contactors.

Entering 2015, as China's economic landscape entered a phase of the "new normal," the frequency converter industry also experienced a noticeable slowdown in growth. Facing severe market challenges, our company defied the trend and achieved robust performance in both production and sales during the first half of the year. With a continuous influx of new clients, product sales increased by over 60% compared to the same period last year.

January 18, 2015, marks the fifth anniversary of the company's founding.
