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.

Description

technical field [0001] The present disclosure relates to a method of manufacturing a doorstep or sill. Background technique [0002] Particular embodiments relate to a method of manufacturing a door step or a door scuff, which allows a door step or a door scuff by inserting a plastic sheet into a mould, and then injecting polypropylene (PP) material for the trim. There is a one-piece construction in which the plastic plate is manufactured by infusing acrylonitrile-butadiene-styrene (ABS) material and utilizing plastic plating. [0003] Typically, a door step or sill for a vehicle is a body mounted trim and is not usually exposed to the outside, yet provides an aesthetic appearance to the occupant when they open the door to enter the vehicle. [0004] A doorstep or sill for a vehicle applied to a vehicle with high ground clearance, such as an RV vehicle, serves as a foothold to help passengers enter the vehicle. [0005] A door step or sill for a vehicle is manufactured by ...
