Modern High Pressure Die-casting Processes for Aluminium Castings
There are about 33 processes commercially available for the production of aluminium castings. About 70% of the castings are produced using conventional high-pressure die-casting process. It’s main drawbacks are 1) Air and gas blow holes 2) Unable to weld 3) unable to heat treat to enhance mechanical properties. To overcome these, many modern processes have been invented. A few of them are 1) Hi...
متن کاملHigh pressure die casting of Fe-based metallic glass
Soft ferromagnetic Fe-based bulk metallic glass key-shaped specimens with a maximum and minimum width of 25.4 and 5 mm, respectively, were successfully produced using a high pressure die casting (HPDC) method, The influence of die material, alloy temperature and flow rate on the microstructure, thermal stability and soft ferromagnetic properties has been studied. The results suggest that a stee...
متن کاملMaterials on Dies for Pressure Die Casting
In the contribution the stress of die materials of thermal fatigue is defi ned and material life is derived theoretically and compared with the measured values. The important properties of the die materials as thermal conductivity, coeffi cient of thermal expansivity, modulus of elasticity and mechanical properties are described. Binding to it single die materials as carbon steels and chrome-tu...
متن کاملApplication of TPM indicators for analyzing work time of machines used in the pressure die casting
The article presents the application of total productive maintenance (TPM) to analyze the working time indicators of casting machines with particular emphasis on failures and unplanned downtime to reduce the proportion of emergency operation for preventive maintenance and diagnostics. The article presents that the influence of individual factors of complex machinery maintenance (TPM) is ...
متن کاملThree-dimensional Numerical Simulation of Metal Flow and Solidification in the Multi-cavity Casting Moulds of Automotive Components
The liquid metal flow and the solidification behaviours in a multi-cavity casting mould of two automotive cast parts were simulated in three dimensions. The commercial code, FLOW-3D® was used because it can track the front of the molten metal by a Volume of Fluid (VOF) method and allows complicated parts to be modeled by the Fractional Area/Volume Obstacle Representation (FAVOR) meth...
