3.1 HyperXtrude simulations HyperXtrude is commercial software for simulation which was produced by Altair Inc. It is good at and special for die design and material flow in the extrusion process of metals and polymers. If the simulations are accurate enough for different profile designs and thermo-mechanical behavior of the billet materials‚ it is very important for die designers and production engineers to predict and reduce the cost of die trials. It is of very practical for producing balanced

------------------------------------------------- Electroplating Electroplating is a plating process in which metal ions in a solution are moved by an electric field to coat an electrode. The process uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material‚ such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g.‚ abrasion and wear resistance‚ corrosion protection
