Productivity Improvement by Increasing Tool Life of Hot Extrusion of Cold Drawing Operation

Abstract

With the growing industrial development and globalization, there is a demand for high quality product to produce in minimum lead time. The manufacturing process of mechanical components plays a vital role in the product's life span. Structure component such as u channel, L channel shape angle and rectangular bars are manufactured through extrusion process. In hot extrusion process, manufacturing defects may occur due to fault die tools. The material of die, its chemical composition, physical properties, geometry of the components and machining process also affect the strength of finished product.

Aiming to resolve the faults occurring in L shape angle, the hot extrusion and cold drawing manufacturing process has been studied for defects and their causes. Further modification in the die tool has also been implemented for improving the quality of the product and in turn the improvement in productivity.
