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 کاملA monitoring and control framework for lost foam casting manufacturing processes using genetic programming
Monitoring and control of manufacturing processes is an essential part of any industry. Being able to collect sensor measurements, analyse the measurements in an intelligent way, select appropriate actions and validate the desired results of these actions is a tremendous goal to be achieved. In this paper, we propose a monitoring and control framework of a multi-tier closedloop controlling lost...
متن کاملReal-time Embedded Sensing for Process Monitoring and Quality Control in the Lost Foam Casting Process
The Lost Foam Casting (LFC) process employs a sacrificial foam replica of the desired casting that is supported by an unbonded sand mold through an overhead raining and flask vibration stage. Generally, the raining and vibration is programmed to a pattern-specific schedule to adequately promote fluidized sand flow into pattern cavities and produce proper densification. Currently, a lengthy tria...
