Production Process According to different dimensions and conditions of use, tungsten crucibles have different production processes. Crucibles generally have shapes such as round, square, rectangular and V-shape. Producing processes include sintering, welding, stamping, and spinning; in which sintering is used most widely.For micro or small tungsten crucibles,forged tungsten rods lathing or stamping process can be used. Tungsten welding process needs rolled tungsten plates to be hot bended and then weld it to fix. Spinning process is mainly used for producing thin-walled tungsten cr ucibles which have high technical requirements.
