Extrusion honing using mixtures of polyborosiloxanes and grit
Extrusion honing is a technique used for the finish machining of engineering components. The process may be used to deburr, radius or polish depending on the specific application. Extrusion honing utilises a polyborosiloxane polymer, which is mixed with fine abrasive particles and forced through or …

Optimization of modular die design in extrusion process
Aluminum extrusion is a metal forming process used for the production of a large variety of solid, semi-solid and complex hollow products. During extrusion, the hot aluminum billet goes under severe plastic deformation as it is forced to flow through a smaller die cavity that defines the final …

Investigation of die wear by modelling the extrusion of Inconel 718
Die wear is always an important issue in hot forming processes, such as in forging and extrusion. Die life affects the economics of process to product and in order to optimise die life, the mechanism of wear should be approached scientifically. The aim of this work is to provide a systematic method …
