The present invention provides a plating method of forming a plating layer with excellent peeling strength on a surface of an injection molded object made of a polyphenylene sulfide (PPS) composite. According to the present invention, the plating method of an injection molded object made of a PPS composite comprises: a step of removing a skin layer of an object to be plated; a step of improving surface roughness of the object to be plated and forming pores; a step of annealing the object to be plated; and a step of forming the plating layer. 본 발명은 PPS 복합소재 사출물 표면에 박리 강도가 우수한 도금층을 형성할 수 있는 도금방법을 제시하는 것으로, 본 발명에 따른 PPS 복합소재 사출물의 도금 방법은 피도금물의 스킨층을 제거하는 단계; 피도금물의 표면 조도 개선 및 기공 형성 단계; 피도금물을 어닐링하는 단계; 및 도금층 형성단계를 포함하는 것이다.
