Design of porthole aluminium extrusion dies through mathematical formulation

A mathematical approach to solve the porthole die design problem is achieved by statistical analysis of a large amount geometric data successful designs. Linear and logarithmic regression are used analyse geometrical 596 different ports from 88 first trial dies. Non-significant variables or high correlated discarded according knowledge extrusion process criteria. This paper focuses on validation model for typical case dies: four cavities per cavity formulation way summarizing in single expression experience accumulated number designs over time. broad research open generalise this extend it other types
