Behavior of Generated Gas in Lost Foam Casting
In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...
متن کاملAn Overview of Lost Foam Casting Technology Development in China
China has had an unprecedented economic boom within the foundry industry in the past two decades. Lost foam casting technology has gained increasing popularity during this time. In China, about two hundred foundries have lost foam casting operations with total annual casting production of approximately 300,000 tons in 2006. This paper reviews the current lost foam casting industry in China with...
متن کاملThe Effects of Gating Systems on the Soundness of Lost Foam Casting (LFC) Process of Al-Si Alloy (A.413.0)
The effects of gating systems, number of runner, and their locations, in the Lost Foam Casting (LFC) of Aluminum alloy (A.413.0) were investigated. Six different gating systems, with one or two running systems were designed. X-ray radiography and the three axis-bending tests have been employed to evaluate the casting soundness and quality. The results revealed that gating systems have a major e...
متن کاملstudy of effective parameters of coating on internal pores in cast iron parts produced by lost-foam casting
in this study, the microstructure and properties of foam glass obtained as a result of the interaction of the waste glass with sic as the foaming agent and fe2o3 as the oxidizing agent have been investigated using scanning electron microscopy (sem), as well as three-point bending and pycnometery tests. first, the temperature and optimized amount of sic for making foam glass was determined. the ...
متن کاملIndirect Rapid Molds for Prototype Lost-Foam Pattern Production
Lost-foam (also known as Expendable Pattern Casting, EPC) is an ever-growing metal casting technique, capable of producing complex metal components without parting lines. Mold preparation for lost-foam casting is typically accurate, but expensive and slow. The goal of this research was to develop a new approach for producing rapid lost-foam molds. With this new approach, patterns generated by S...
