Description
Our JJL series polysilicon casting furnace is one of the key equipment employed in the mass production of high quality poly silicon ingots. The furnace is designed with world-prevailing electrical resistance heating method and advanced computer control technology to achieve stable ingoting. Our polysilicon casting furnace manufacturing is mainly realized through vacuum furnace, heating and thermal insulation system, power supply and control system, vacuum and air supply system, water cooling system, steel frame, staircase, etc. Our latest generation of JJL 1T multi-crystalline furnace is the largest model that has been put into commercial production in the international market. Our multi-crystalline furnace fabricating service assures all its technical indexes to reach world leading level.
Advantages
1. As a part of our polysilicon casting furnace manufacturing service, we mainly undertake the manufacturing of the vacuum furnace. Our welding, precision processing and painting treatment assures the high precision of the furnace, making it safe to work under the high temperature of 1500°C.
2. The furnace is made of stainless steel, and the top of the furnace is formed through the punching of a 2000T hydraulic press. We are equipped with a number of machines to fabricate multi-crystalline furnaces, including vertical milling-boring machine, CNC machining center, rotatory milling machine, etc. Our polysilicon casting furnace manufacturing can be carried out in stainless steel, carbon steel, aluminum, etc.
