Abstract:
The continuous extrusion process is a process for producing endless profiles with a
high degree of accuracy. The two important and vital process parameters are extrusion wheel
velocity and product diameter which affect the mechanical and metallurgical properties of the
material. In this work, continuous extrusion of pure copper (C101) rod has been carried out on
commercial setup TBJ 350 for feedstock diameter of 9.5 mm at different extrusion wheel
velocities and product diameters using different die sizes. The yield strength and percent
elongation of extruded feedstock at different wheel velocities and product diameters has been
estimated by carrying out the tensile test. The continuous extrusion process has been carried out
based on two factor three-level central composite rotatable design using response surface
methodology. A mathematical model has been developed to predict the mechanical properties
of the extruded feedstock through continuous extrusion process and its validation has been
carried out using ANOVA technique.
