Attendees in ClassNameCompanyPositionUsed flow analysis before? Moldflow? Others?Hardware usedReason for taking training course
Overall cooling system performance is determined by the following contributors:Rate of heat transfer from the plastic to the mold wallRate of heat transfer from plastic/metal interface to the coolant/metal interface, that is, through the moldRate of heat transfer from the coolant/metal interface to the coolant
The heat transfer rate is influenced by the following:Material properties of the meltSpecific heatThermal conductivityTemperature gradient between the melt and mold wallQuality of contact between plastic and mold wallSoftware assumes 100% contact, that is, Tmold=Tpart at mold wall
