摘要

Material properties and boundary conditions are important inputs for any simulation. For the injection molding process, there are still many challenges to measure the polymer properties under processing conditions and there is not consensus about the thermal boundary conditions between the polymeric material and mold walls. This work is oriented to analyze the effect in the simulation results of the heat transfer coefficient (HTC), which is related to the boundary conditions, and the no-flow temperature (NFT), which is related to the material rheological behavior. The results for cavity pressure and temperature evolution from three well-known commercial software packages (CadMould~R, MoldFlow~R and Moldex 3D~R) were analyzed and compared with experimental measurements. A semicrystalline material, PP 505P, from Sabic was used. In particular, the variation effect of heat transfer coefficients (HTC) and no-flow temperatures (NFT) were analyzed through a 3~2 factorial design of experiments (DoE). Based on the results, the most recommendable criteria to determinate NFT and HTC values for a semicrystalline material is proposed. The physical meanings of the obtained values are discussed.
