Squeeze casting is a process that can produce the highest quality castings. In current study, effect of settings and in-die conditions on rejection rates studied through full-scale experimental study. Factors affecting as-cast part were investigated in study from two different viewpoints. The first was to investigate influence rate, second understand die effects rate better reasons sensitivity ...

Article history: Received:29.09.2013. Received in revised form: 17.12.2013. Accepted: 24.12.2013. A three-dimensional Computer Aided Design (CAD) model of the bearing sleeve casting is established by Pro/E software. The ViewCast program is utilized for studying casting processes of solidification and mould-filling in order to optimize the casting technology. Based on the solidification simulati...

In a foundry casting line, contaminants are released from a large area. Casting fumes include both volatile and particulate compounds. The volatile fraction contains hydrocarbons, whereas the particulate fraction mostly comprises a mixture of vaporized metal fumes. Casting fumes lower the air quality in foundries. The design of local ventilation for the casting area is a challenging task, becau...

The materials of the article consider effectiveness additives for stabilization and dilution clay-free slippers. For theproduction radio-transparent ceramic Celsius-Willemite composition, most efficient energy-saving methodof production is method slip casting. According to charge this technology complicated by lack claycomponents, which shows need use impurities improve rheology such a slip. ma...

Although the role of dental casting alloys has changed in recent years with the development of improved all-ceramic materials and resin-based composites, alloys will likely continue to be critical assets in the treatment of missing and severely damaged teeth. Alloy shave physical, chemical, and biologic properties that exceed other classes of materials. The selection of the appropriate dental c...

A hierarchical representation formed by an octree for a volume ray casting is a well-known data structure to skip over transparent regions requiring little preprocessing and storage. However, it accompanies unnecessary comparison and level shift between octants. We propose a new data structure named half-skewed octree, which is an auxiliary octree to support the conventional octree. In preproce...
