Transcript of Glass Pressing Simulation Study of glass pressing simulation of high temp.
An efficient method for analysis and design of industrial products or process
(Glass Pressing Simulation )
Glass Pressing Simulation Study of glass pressing simulation of high
temp. Software for Pressing simulation (POLYFLOW,
DEFORM) is very expansiveUsed ANSYS for Analysis pressing simulation
