Optimizing process parameters to reduce blowholes in high pressure die casting using Taguchi methodology
N. Rathinam ⇑, R. Dhinakaran, E. SharathDepartment of Mechanical Engineering, Pondicherry Engineering College, Pillaichavady, Puducherry, 605014, India Abstract Products manufactured from every manufacturing process exhibit some defects. To supply quality products to the customer these defects must be reduced. The motivation for this work is to reduce defects in end products reaching customers, thereby increasing
