BACKGROUND Traditionally, inlay casting waxes have been used to fabricate patterns for castings. Newer resin pattern materials offer greater rigidity and strength, allowing easier laboratory and intraoral adjustment without the fear of pattern damage. They also claim to possess a greater dimensional stability when compared to inlay wax. AIMS This study attempted to determine and compare the m...

The article deals with the rationalization of production shaped inserts for casting rotors. theoretical part describes characteristics rotor casting, die technology, analysis existing technology inserts. main is focused on proposed technological process production, comparison and process. concludes a technical economic benefit solution evaluation work. Rationalization has its justification in d...

New Nissan to feature complex aluminum castings The new Nissan GT-R features aluminum inner-door and rear-seat structures made from Alcoa’s proprietary vacuum die casting process (AVDC) at the company’s plant in Soest, Germany. Both components also feature new proprietary alloys developed by Alcoa. The new C-446 alloy, in combination with the unique advantages of the AVDC process, enabled Alcoa...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

the influence of aluminium on the microstructure of austempered ductile cast iron (adi) has been studied. anumber of irons of different compositions have been made by green sand casting and gravity die casting ofappropriate design to provide the experimental materials. austenitising was carried out at different temperaturesand holding times for a variety of experimental irons to achieve suffici...

Several factors can contribute to the final part quality in a High Pressure Die Casting process, terms of roughness, porosity and strength. The injection velocity, cooling die aluminium’s inlet temperature are some that have higher effect on quality. new advances process digitalization, sensortization simulation tools, combined with artificial intelligence techniques allow developing functional...
