Over the last couple of years, Castool (a tool designer and manufacturer for the extrusion industry) havex000D
developed a software tool called VOS (Visual Optimization Software). The original purpose for this softwarex000D
was to assist extrusion plants in optimizing the productivity of their extruders based on the alloy and profilex000D
they were extruding. Although the original intent was to use the VOS to help optimize and predictx000D
productivity, the reality is that VOS has ended up more as a die database with historical information. What isx000D
lacking is the quantitative knowledge of the relationship between the extrusion variables and the pressurex000D
required and exit temperature. Castool has started to put together something more useful from the VOS whichx000D
will tell the extruder what productivity they can expect for any combination of profile, die, billet and pressx000D
set-up however the still lack quantitative knowledge on the relationship between these variables.x000D
Initially, Castool was going to convert real pressure data (from Almag in Brampton) into temperature andx000D
therefore speed, but this is so approximate that it is unlikely to be of great use. Castool intend to continue thisx000D
conversion of pressure to temperature but had difficulties getting good information from Almag.x000D
What Castool would like to do now is develop a simple and fast, almost real-time, parametric models with thex000D
variables, extrusion ratio, billet temperature, container temperature and predict maximum speed and diex000D
bearing and extrusion exit temperatures.x000D
The focus of this research will be to develop a mathematical model to accurately predict the temperature andx000D
extrusion load for a range of cases so that correlations between the tooling temperature, extrusion ratio, ramx000D
speed and billet temperature can be made with respect to extrudate temperature upon exit and pressure during
