Real-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...
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...

انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
15 صفحه اولAn Investigation into the Effect of Process Parameter Settings on Air Emission Characteristics in the Lost Foam Casting Process
The lost foam casting process offers several advantages over traditional green sand casting, most notably the ability to reuse casting sand, thus eliminating the need for costly disposal of contaminated casting sand. The process does, however, produce significant quantities of airborne emissions that can be a danger to both the environment and to the health of workers. This research examines th...
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...
