摘要： A method for making a composite piece comprised of a metal part and a glass-fiber-reinforced plastic part, comprising: providing a metal part with a receiving cavity and a flow guiding channel, the flow guiding channel having an inlet communicating with the receiving cavity and an outlet; introducing molten plastic reinforced with glass fibers into the receiving cavity to fill the receiving cavity and the flow guiding channel and overflows from the outlet to form a flash section; curing the molten plastic to obtain a plastic part; removing unwanted portion of the metal part together with a portion of the plastic part to obtain the composite piece, wherein the glass-fiber-reinforced plastic part includes an exposed surface and glass fibers exposed at the exposed surface are substantially parallel to each other. A metal-plastic composite part prepared by the method and an electronic device housing are also disclosed.
