Abstract: Abstract The PIM mold filling analysis is based on two-dimensional layer flows assumptions for thin cavity filling under non-isothermal conditions. The mathematical model that described PIM filling process is created, and the formula that calculated the flow conductance is deduced. The pressure equation for the liquid phase is obtained as $$ {\partial \over {\partial x}}\left( {s{{\partial p} \over {\partial x}}} \right) + {\partial \over {\partial x}}\left( {s{{\partial p} \over {\partial x}}} \right) = 0 $$ which is a non-linear elliptic partial differential equation. It calculates for the model possible and lays a mathematical foundation for further analyzing the PIM mold filling flow.
