Melt spinning method for the direct manufacture of metallic fibres and filaments from molten metal is more economical and more mass-productive than bundle drawing method or Taylor method. Its application, however, has the problems in finding out suitable materials for orifices and crucibles, in working orifices, and in grasping the condition of the ejected stream of molten metal. Therefore, there are few research reports on this method. B. Lux reports that the melt spinning method in which a

But in this method stainless orifices of 100µm in thickness is used, so as to decrease the resistance against the ejected stream through the orifices, and it easily manufactures the fibres of less than 100µm in diameter in the experiment in which molten tin is used. As the diameter of the orifice grows smaller and smaller, fibres with a smoother surface are obtained. Under the present experimental condition where the ejection temperature is 300'C, the longest fibre, of 23µm in diameter and of 347 cm in length, is obtained.
