A new rapid die_manufacturing technology with the combination of electric arc spraying and brush plating was proposed. By using the electric arc spraying technology, a thin layer of dense and low_melting_point metal was rapidly deposited on the surface of the master die so as to make the cavity of the die; then by using the electric brush plating technology, a reinforcing layer was plated on the working surface of the die to markedly increase the hardness and wear_resistant property of the die surface. An equipment for rapid die manufacture with the combination of electric arc spraying and brush plating was introduced. The rapid die_manufacturing method and device used for the development of new models of automobiles and trial manufacture of sample cars could greatly reduce the development cost and shorten the development cycle.
