Porosity 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 ...

Automated Radioscopic Inspection of Aluminum Die Castings

Castings produced for the automotive industry are considered important components for overall roadworthiness. To ensure the safety of construction, it is necessary to check every part thoroughly using non-destructive testing. Radioscopy rapidly became the accepted way for controlling the quality of die cast pieces. In this paper the fundamental principles of the automated detection of casting d...

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...

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...
