A Review on Un filling Defect Found In Forging Process

The objective of this paper is to find defects in forging process. Causes for unfilling defects are discussed and remedies for the unfilling defect would help to improve the quality of forging product. It is concluded that proper forging technique, improving die design, proper heating of billet reduce the unfilling defect. Simulation in FEM based software DEFORM 3D helps to detect unfilling defect and using discussed remedies help to reduce rejection rate.
