This paper describes about cold plastic forming of ABS plastic pipe. Experiment and Finite element method (FEM)<br />
analysis of pipe expansion process were operated. The application of ABS plastic pipe for air conditioner is under<br />
consideration instead of metal pipe in Japan because of weight saving of air conditioner for lowering the gravity<br />
point against earthquake. The parts of ABS plastic pipe is generally produced by injection molding. The processes<br />
need the cooling time, and it takes much time. In addition, expensive mold die is needed for each application. Thus,<br />
cold plastic forming of ABS plastic pipe was proposed. The cold plastic forming of ABS plastic pipe chosen for<br />
this study is hardly studied by other authors. Product ability of cold plastic forming is higher than the injection<br />
molding or hot working. And the punch and die shape is simple comparing to these process. In this study, pipe<br />
expansion process was operated. The ABS plastic pipe has a 10 mm diameter and 8mm inner diameter and 1 mm<br />
thickness. At first, true stress and true strain curves at any strain rate were measured by ring compression test.<br />
Obtained flow stresses was used to FEM a
