Residual Stresses in Castings Produced by Press Die Casting Technology
D. Novoselović, I. Budić, I. Samardžić, Mechanical Engineering Faculty in Slavonski Brod, University of Osijek, Croatia The influence of technological parameters on residual stresses in pressure die castings is analysed in this paper. In order for the residual stresses to be as low as possible the optimization of technological parameters is necessary. The centrally composed plan of experiment 2...
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...
متن کاملPorosity Control in Copper Rotor Die Castings
This paper reports on the results of an investigation to minimize and control the distribution of porosity in edge-gated copper rotor die castings. A Flow 3-D computer modeling exercise was used to simulate shot profiles that result in formation of large pores in the end rings, as well as to predict improved profiles that will reduce or eliminate the residual porosity. These model results were ...
متن کاملAluminium Foam and Magnesium Compound Casting Produced by High-Pressure Die Casting
Nowadays, fuel consumption and carbon dioxide emissions are two of the main focal points in vehicle design, promoting the reduction in the weight of vehicles by using lighter materials. The aim of the work is to evaluate the influence of different aluminium foams and injection parameters in order to obtain compound castings with a compromise between the obtained properties and weight by high-pr...
متن کاملEFFECT 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...
