The extrusion cycle is generally longer than the forward extrusion. But because the size and the quality of the ingot blank can be increased, the residual pressure loss is less, and the extrusion speed is high, the increase of the auxiliary time is compensated to a certain extent, and the backward extrusion has higher production efficiency. The backward extrusion production process is widely applied and has an ascending trend.
