Abstract
The squeeze casting process is a metal casting process that requires a tool called extortion. Diess on casting is a component that determines checking performance. Based on this excuse, it is necessary to do a performance analysis (thermal) on squeeze casting to determine components performances. This study aims to determine the performance of the diess in squeeze casting which requires the allocation of heat that occurs and thermal efficiency diess. This research was conducted with a real experimental method with variations in testing at temperatures of 100ºC, 200ºC, 300ºC, and 400ºC using Magnesium AZ31 material and combined with aluminum. From the results of research published on the biggest thermal heater that is at a temperature of 400° C of 970.68 W with a thermal efficiency of 18%. While the heat that occurs at a temperature of 100ºC is 489.25 W and thermal efficiency is 9%, at a temperature of 200ºC is 806.28 W and thermal efficiency is 15% and at a temperature of 300ºC is 864.98 W and thermal efficiency is 16%.Keywords: Temperature, diess, squeeze casting performance.

Summary
Pengecoran logam merupakan suatu proses pembuatan benda dengan metode mencairkan logam dan menuangkannya kedalam rongga cetakan. Pengecoran logam dapat dilakukan dengan berbagai macam bahan baku logam seperti besi, baja paduan tembaga dan lain-lain. Proses squeeze casting atau yang biasa disebut dengan penempaan logam cair (liquid metal forging) adalah suatu proses yang mengkombinasikan keuntungan atau kelebihan dari proses forging dan casting. Pada sistem pengecoran istilah pengecoran semi solid adalah proses pengecoran bahan logam dimana dalam proses tersebut material berada pada kondisi fasa cair dan padat atau yang biasa disebut fasa semi solid. Kondisi semi solid pada proses pengecoran ini diperoleh dengan melakukan proses memanaskan diatas temperatur solid. Pada pengecoran semi solid ada beberapa faktor yang mempengarhui hasil dari proses pengecoran itu sendiri, diantaranya yaitu temperatur tuang sangat berpengaruh terhadap struktur mikro serta kekerasan.
