Using advanced quartz tube secondary forming equipment, the quartz tube can be secondary processed into two types: continuous melting secondary forming tube and gas refining secondary forming tube, which can provide a secondary forming quartz tube with an outer diameter of 80 - 600 mm and a wall thickness of 2 - 7 mm. The product is accurate in size and good in thermal stability, and is mainly used for processing diffusion tubes and other corrosion-resistant and high-temperature resistant places in the solar and semiconductor industries.
