Automotive weather strip manufacturing: Process modeling and extrudate dimensional accuracy evaluation

摘要

This paper presents the computational modeling results of the rubber extrusion manufacturing process. The impact of the die swell phenomenon is quantified by running iterative models, differentiating the inflow rate. The extrudate's dimensions are identified by making use of image processing algorithms for detecting the edge. Also, the velocity values at the outlet are calculated for various inflow rates and are presented graphically. The generated rules are correlating the manufacturing parameters with the Key Performance Indicators (KPIs) and can predict the extrudate's dimensions towards zero defect manufacturing.
