We have the exclusive patent products, research and produce the semiconductor key equipments. The outstanding advantage of its production is to take some techniques such as the plc auto-controlling system, independent innovating hot zone, magnetism liquid seal, power factor compensation and harmonic wave restraining and so on, which realizes the constant temperature of the hot zone, meets steady, continuous, high-efficiency, auto-controlling, non-dislocation and low oxygen and carbon requirements for dia.6inch--dia.8inch single silicon ingot. The products are high-efficiency, economize on energy, environmental protection and automatization , has the perfect foreground. Cz-80a Cz-90ai Cz-110
