3D Scanning Techniques Complements Predictive Engineering for Mold Flow Analysis

Abstract:

This study is an attempt to close the loop between simulation and reality. Many industries are of the opinion that a simulation does not really predict the actual process and is only a colorful plot for presentation. An accurate simulation can save cost by a multitude of ways like material savings, process optimization, cycle time reduction, improved quality of parts and so on. A validation of the simulation in a real time scenario will instil necessary confidence in the accuracy of the simulation study thereby closing the loop between simulation and reality In the present study, the mold flow analysis is conducted for the back plate of LED emergency light with the help of Autodesk moldflow simulation software to generate the gate location, feed system building, cooling channel wizard, fill time and to check warpage and then the result is verified by superimposing the scan data of the physical part which is scanned in Steinbichler Blue Light 3D Scanner and CAD model in Geomagic verify.
