Abstract

사판식 압축기에 사용되는 피스톤을 저렴하게 제작할 수 있을 뿐만 아니라 내마모성을 향상시킬 수 있도록 본 발명은 혼합재를 주형에 주입시켜서 모재를 형성시키는 제1단계와 상기 모재에 함유되어 있는 바인더가 증발될 수 있도록 상기 모재를 가열시켜서 기공성 모재를 형성시키는 제2단계와, 상기 기공성 모재를 주형틀에 장착시키는 제3단계와, 상기 주형틀에 용융상태의 알루미늄 합금재를 주입시키는 제4단계와, 상기 주형틀에 압축시키는 제5단계로 이루어진 제작 방법을 제공한다.In order to not only manufacture the piston used in the swash plate compressor at a low cost, but also to improve wear resistance, the present invention provides a first step of forming a base material by injecting a mixture into a mold so that the binder contained in the base material can be evaporated. A second step of heating the base material to form a porous base material, a third step of mounting the pore base material on a mold, a fourth step of injecting a molten aluminum alloy material into the mold, and Provided is a manufacturing method comprising a fifth step of compressing the mold.
