Abstract: A method of manufacturing an automobile comprising: mixing 96˜99 wt % of colored plastic powder with 1˜4 wt % of transparent irreversible thermochromic pigment powder thus preparing a material mixture for a fuse body; melting the material mixture using an injection molding machine so that the fuse body containing a thermochromic pigment component is molded at an injection temperature of 300˜310° C. and an injection pressure of 1200˜1600 kg f/cm2 using an injection mold; drying the fuse body containing the thermochromic pigment component at 100˜200° C. for 3˜5 hr; inserting a fuse element comprising a pair of terminal members and a fuse member fixed therebetween into a pair of terminal insertion recesses and a fuse charging recess of the fuse body containing the thermochromic pigment component.

Abstract: An automobile fuse is provided wherein short circuit of the fuse can be easily identified by naked eye through change of color when a fuse short circuits, and provides an automobile fuse manufacturing method, comprising: the fuse body material mixing step (S1) of mixing 96˜99 wt % colored plastic powder and 1˜4 wt % transparent irreversible thermochromic pigment powder to prepare a mixture material.; the fuse body molding step (S2) of melting the mixture material in an injection molding machine to mold a fuse body containing a thermochromic pigment component in an injection mold at an injection temperature of 300˜310° C. and an injection pressure of 1200˜1600 kgf/cm2; the fuse body drying step (S3) of drying the fuse body containing a thermochromic pigment component at 100˜200° C. for 3˜5 hours to reduce the water content of the fuse body to 0.
