Abstract: The present invention relates to a metal fiber manufacturing system. The system casts molten metal as a metal fiber; collects the metal fiber in real time; transfers the metal fiber; separates normal products from defective products; and packages a predetermined amount of the normal product metal fiber. The system processes the cast metal fiber continuously or in batches, and manufactures the same, thereby having effects of improving the efficiency of the production process and obtaining significant economic benefits.
