LISA Thermal Simulation of Hypothetical Mould Tool Being Cooled. Two mould cavities are filled with PA66 of temp 330*C (603,15K) and then cooling occurs. Coolant’s temp is 100*C (293,15K). The tool must be warmed up to approx 100*C (297,15K) to avoid short shots as mould cavities are 15cm deep and 0.5cm wide. Typical thermal values for water, tool steel, copper were chosen to perform simulation.
Due to Graphic Card post processing isn’t as fluent as I would like to but is efficient enough to visualize transient thermal behavior of temperature filed in this case.
