Effect of extrusion ratio on paraffinic mineral oil lubricant in cold forward extrusion

A finite element (FE) analysis is made for steady-state two-dimensional forward extrusion with three different extrusion ratio values. Predicting extrusion force of aluminum billet extruded with palm oil lubricant will definitely be helpful in deciding the right extrusion ratio. Hence, the finite el...
