On the afternoon of October 30, Feng Jianrong, deputy secretary of the county party committee of Shaoxing County, accompanied by Jin Liangshun, chairman of the board of directors of Jinggong Group, Sun Jianjiang, chairman of the company, and Zhao Bo, general manager of Seiko Institute of Mechanical and Electrical Engineering, visited the company's solar polysilicon ingots. Furnace production site.

The solar polysilicon ingot furnace is designed by the company's holding subsidiary Shaoxing County Seiko Electromechanical Research Institute Co., Ltd. for the solar energy industry. It is an essential device for high-efficiency and energy-saving silicon remelting ingot furnace and polysilicon chipping. The furnace mainly adopts the international leading resistance heating technology, uses advanced computer control technology to achieve steady directional solidification, produces high-quality, large-sized polycrystalline silicon ingots, meets the requirements of energy conservation and environmental protection, and has independent intellectual property rights, among which, “an infrared measurement The two technologies, such as the “warm device”, have obtained the national utility model patent, and the five invention patents and six utility model patents of the “polysilicon ingot furnace thermal field energy-saving efficiency device” have been accepted by the State Intellectual Property Office.
