Steady-state module of cooling analysis in injection molding

Cooling system in injection molding is of great importance because it cannot only reduce molding cycle time efficiently but also can improve part quality. Current cooling analysis method is based on boundary element method (BEM). Because the cooling analysis module is so complex, with the same BEM, the equations of the item calculation of coefficient matrix are variable. Different calculation equations cause different problems, which influence its practicability. This article presents a practicable analysis model. Many tests show its result is reasonable.
