Abstract: A dual-injected back counter for a footwear is provided, which is produced through the twice injections, without any complicated processes, like cutting, grinding or polishing, and more doesn't need an adhesive application process in the future. A dual-injected back counter for a footwear, configured as a simplified structure comprises: an injected plastic plate(102), firstly injected by using a thermoplastic synthetic resin, and imparting the functions of shape maintenance and reinforcement of the footwear; and a hot-melt resin layer(104), secondly injected to both sides of the plastic plate without any separate primer processes so as to allow the latter to be adhered to the uppers of the footwear.

Abstract: PURPOSE: A toe cap of safety shoes and its producing method are provided, thereby producing the toe cap of safety shoes having improved anti-shock intensity. A user wearing the safety shoes feels more comfortable because the weight of the safety shoes is minimized. CONSTITUTION: The method for producing the toe cap of safety shoes comprises the steps of: adding 5 to 50 part by weight of shock modifier selected from the group consisting of acrylonitrile-butadiene-styrene copolymer, denatured polybutylene terephthalate and denatured nylon and 5 to 65 part by weight of glass fiber into 100 part by weight of the engineering plastic to produce a toe cap mixture; mounting a metal net on a mold having a toe cap shape; and injection-molding a toe cap by inserting the toe cap mixture into the mold.
