The Ningxia Xinjing New Materials Technology Co., Ltd. Plant II Quartz Crucible Expansion Project Electromechanical Installation Project (Phase II) is located in Yinchuan City, Ningxia Hui Autonomous Region. With a construction area of approximately 45,000 square meters, it is part of the 5-billion-yuan investment plan of Ningxia Xinjing New Materials, aiming to construct 24 crucible production lines in four phases. The quartz crucible is a crucial auxiliary material used in the process of pulling monocrystalline silicon for photovoltaic purposes, mainly for containing molten silicon and forming ingots. The construction scope includes general contracting for the installation of 12 melting furnaces in Phase II, covering high-voltage power supply, high and low-voltage distribution systems, PCW water supply system, pure water system, water supply and drainage system, dust removal system, exhaust system, civil engineering, and decoration, among others.
