- Abstract
- This research covers the development of axi-symmetric plastic elements for injection molding with insert steel such as high stiffiiess Sabot. The functional requirements of Sabot are concentricity and fracture resistance about vertical and horizontal forces. For these, an analysis of characteristics of PEI(polyetherimide) polymer is performed by standard test specimen with accordance of ASTM test guidance. Moldflow analysis and simulation of injection moldir방 process are carried out in order not only to estimate of the warpage but also to predict the characteristics of residual stresses which both product and structure of mold may have. A new vertical side injection machine and transverse mold have been constructed Results of the measuring concentricity and fracture test after molding of Sabot are satisfied to design specification over Cp ratio > 1.33. Finally, this technique needs more research application to others axi-symmetric elements having different radius with insert steel and structure analysis from now on.
