| Abstract | ||
| The paper studied capability of forging process to produce round shape flange using acetal (celconR¬) polymer which is an engineering crystalline material having a good ductility if it is preheated The process done under cold & hot conditions This kind of technique guarantees a product with high strength and stiffness better than what injection molding could achieve. The products showed crack and curling traces on the flange under cold forging, but a good product was achieved by heating the billet and the tools to (100Co)with improvement in the mechanical properties. The paper discussed also through (stress – strain) curves manner of deformation through forging action. The results explained that POM (celconR¬) is forgeable polymer if it is preheated at (100 Co ) using slow speed press by closed die forging process under applied pressure of 170Mpa to produce round shape flange, while this technique failed to forge same polymer at room temperature. | ||
