Effects of Process Parameters on Charge Weld Length during Multi-Hole Porthole Die Extrusion

Abstract:

The evolution of charge weld during multi-hole porthole die extrusion was studied by means of finite element simulation and Taguchi’s design. Moreover, based on S/N analysis, the optimal process parameters that can reduce the charge weld length was obtained, where the billet diameter is 100 mm, extrusion speed is 2.0 mm/s, tool temperature is 430 °C and billet temperature is 465 °C. The accuracy and effectiveness of such optimal process parameters were also verified. The purpose of the present study is to provide some information about the controlling of charge weld for extrusion engineers.
