EFFECT OF REFINING PROCESS ON POROSITY AND MECHANICAL PROPERTIES OF HIGH PRESSURE AL-SI ALLOY DIE CASTINGS
Abstract: This study presents the research results of effect that refining process has on porosity and mechanical properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on samples taken from high pressure die ca...
متن کاملOptimization of Process Parameters of Pressure Die Casting using Taguchi Methodology
The present work analyses different parameters of pressure die casting to minimize the casting defects. Pressure diecasting is usually applied for casting of aluminium alloys. Good surface finish with required tolerances and dimensional accuracy can be achieved by optimization of controllable process parameters such as solidification time, molten temperature, filling time, injection pressure an...
متن کاملModern 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...
