The casting-mold interfacial contact pressure and its effect on the interfacial heat transfer in squeeze casting process were studied, where the contact pressure was measured by using a Kistler pressure transducer and the interfacial heat transfer coefficient (IHTC) was determined by applying an inverse approach based on the temperature measurements inside the mold. The influence of pouring temperature, coating thickness as well as alloy attributes on the IHTC was also discussed. The results show that the higher the applied pressure, the higher the value of the IHTC. The IHTC decreased with the decreasing of the interfacial contact pressure. The coating thickness has an important effect on the IHTC, and it made the effect of the contact pressure declined remarkably. A comparison between the cases of an aluminum and a magnesium alloy showed that the effect of alloy attributes is worthy of being specially considered.
