Abstract
This article discusses the various operations and cause of defects involved in the hot extrusion process, such as the furnace, hot log machine, billet preheating, extrusion press machine, stretching machine, pulling machine, conveyer rollers, cutting machine, and so on. In the extrusion process, hefty tooling and equipment are used. It is vital to understand the relationship between the extrusion press condition, equipment, and their performance measured in terms of productivity and recovery of cost. To understand the defects that contribute to and control the factors that affect the extrusion profile and occur the waste in the forward extrusion process, The quality of the extruded profile is the key function of various factors such as geometric dimension, appearance of profile, variation of mechanical properties over the extruded profile length, shape, cross section, and surface finish. Most extrusion profile defects may arise because of billet material and billet size selection by manpower. In the article to describe to reduce the waste and discard in forward extrusion process.
