![]() ![]() These drawbacks restrict the development and widespread application of the LFC process. Yet, despite its popularity, it still suffers from some technological problems, such as poor filling ability of the castings, coarse and non-dense microstructure, low mechanical properties for the Al and Mg LFC processes, and defective carburization for the low carbon steel LFC process. Lost foam casting (LFC) is a green precision casting process categorized as a near net forming technology. Novel technologies for the lost foam casting process The discussion highlighted areas needing further attention, which included: — Designers need to design for casting, not The object of the.Specialist Meeting was to present the current state of developments of advanced casting technology, and to bring together designers and materials and.significantly in the near future. Another big project in order to develop wide strip casting technology for the automotive applications of magnesium sheets was started in succession.Ĭomponents with consequent cost and weight benefits but there is traditionally a reluctance by designers to trust castings. POSCO has completed the world's first plant to manufacture magnesium coil. Research on magnesium sheet production technology started in 2004 by Research Institute of Industrial Science and Technology (RIST) with support of Pohang Iron and Steel Company (POSCO). Choo, D.Įxtensive investigations relating to the production of high performance and low cost magnesium sheet by strip casting have been performed for the application to automotive parts and electronic devices. Wide Strip Casting Technology of Magnesium Alloys Three articles discuss (1) casting technology as it relates to industry, with comparisons of shell casting, shell molding, and die casting (2) evaporative pattern casting for metals and (3) high technological casting with silicone rubber. ![]() The adoption of these changes in industrial practice has direct implications on the cost of casting and foundry costs default.ĮRIC Educational Resources Information Center This requires the use of two mould-parts, re-dimensioning of the core and the core box and dimensioning of the runner network. Thus, to reduce the percentage of defects registered in industrial practice is necessary to change the moulding-casting technology. The current moulding-casting technology involves moulding into three mould-parts leading to the occurrence of defects (decentering of the core, displacement of the lower mould and the middle mould and occurrence of burrs in area separated. The casting analysed is a medium size, with weight of 114 kg. This casting is a subset of the lifting and rotating mechanism of the furnace vault. The paper presents the critical analysis performed on moulding-casting technology of the type Lifting mechanism. In this context, quality assurance is the overall objective of the foundries. The quality of castings has a particularly role in the Romanian foundries. Research on the influence of moulding-casting technology on the quality of castings
