Abstract
A method of manufacturing a doorstep or a door scuff is provided. The method includes an ABS material injection step of injecting an acrylonitrile butadiene styrene (ABS) material to have a doorstep (or a door scuff) shape; a plastic plating step of plating an ABS material with plastic; and a PP injection step of fixing the ABS material plated with plastic in a mold, and injecting PP to the ABS material fixed in the mold so that the ABS material and a polypropylene (PP) material have a one-piece structure.
