Using foam injection molding (FIM) in Moldex3D, FCU used recyclable molding material (SEBS elastomer) to predict the configuration influence of the gate and the change of molding pressure for hot melt with micro bubbles in the filling process. By integrating simulation and experimentation, they verified the impact of gate location and thickness variation on bubble structure and distribution. The final results showed that using foam injection molding can replace foaming agents and reduce product weight by 10%.
