A thermal-stress modelling methodology in ABAQUS for fundamentally describing the die/casting interface behaviour in a cyclic permanent die casting process

Journal of Materials Research and Technology, 2021
This manuscript describes a novel method for thermal-stress modelling of a cyclic, permanent die casting process in the commercial software package ABAQUS. The key element in this method is that it updates the casting's geometry according to the deformed

On the Use of Conformal Cooling in High-Pressure Die-Casting and Semisolid Casting

Technologies, 2021
Today, tool life in high pressure die casting (HPDC) is of growing interest. A common agreement is that die life is primarily decided by the thermal load and temperature gradients in the die materials.

Pengendalian Kualitas Produk Downlight dengan Implementasi Simulasi Die Casting

Rekayasa, 2023
Die casting is a casting process in which molten metal is poured into a mold by injection using a piston driven by pneumatic/hydraulic energy. In some cases, the resulting product does not match the desired design because defects will occur if the ...

Formation, characteristics and control of sludge in Al-containing magnesium alloys: An overview

Journal of Magnesium and Alloys, 2022
Sludge consisting of heavy element phases and oxides is often generated during the casting operation of aluminum (Al) and magnesium (Mg) alloys. With the help of the well-established Sludge Factor (SF) formula, it is relatively easy to control the sludge
