N2  - Thermal resistances in the mould, die-mold interface and mould material are most important parameters for produced material’s mechanical, physical and solidification properties in die casting. Particularly, determining of heat transfer in die and mould is important for quality of die material. For this aim, die-mould interfacial heat transfer coefficient (IHTC), temperature distribution and heat flux are determined according to different mould initial temperatures during injection process of A413 aluminum-silicon alloy. Temperatures are measured based on time by 24 pieces of thermocouples which are mounted at different depths of die and mould material. Measured and calculated temperature values are concordant. Interfacial heat transfer coefficient (h) and heat flux (q) are calculated with finite difference method (FDM) by FORTRAN programming language using experimentally measured temperatures values. Additionally, dynamic parameters of cold chamber machine (injection pressure and speed) are recorded with dynamic parameter measuring device as a function of time. As a result, interfacial heat transfer coefficient, temperature distribution and heat flux are determined as a function of time. The variations of heat transfer coefficients and heat flux are presented according to mould initial temperatures
