his paper describes about cold plastic forming of ABS plastic pipe. Experiment and Finite element method (FEM) analysis
of pipe expansion process were operated. The application of ABS plastic pipe for air conditioner is under consideration
instead of metal pipe in Japan because of weight saving of air conditioner for lowering the gravity point against earthquake.
The parts of ABS plastic pipe is generally produced by injection molding. The processes need the cooling time, and it takes
much time. In addition, expensive mold die is needed for each application. Thus, cold plastic forming of ABS plastic pipe
was proposed. The cold plastic forming of ABS plastic pipe chosen for this study is hardly studied by other authors. Product
ability of cold plastic forming is higher than the injection molding or hot working. And the punch and die shape is simple
comparing to these process. In this study, pipe expansion process was operated. The ABS plastic pipe has a 10 mm diameter
and 8mm inner diameter and 1 mm thickness. At first, true stress and true strain curves at any strain rate were measured by
ring compression test. Obtained flow stresses was used to FEM analysis. Experimental device for pipe expansion process was
made by Dip Inc.. Objective inner diameter was 10 mm. FEM analysis was operated to clarify the deformation behavior such
as load-stroke diagram. It was possible to produce the expanded ABS pipe. The whitening of worked pipe and strain recovery
was observed. Analysis result was indicated the good agreement comparing to experimental result in load-stroke diagram.
