Foundry in developing nations endures from low quality and low output due to the incidence of defects that may occupy single or multiple causes. Hence casting is a process of uncertainty. It is not an easy task, since casting is a complex process and has connections among various process and operations. Casting defects can negatively impact the bottom line of a foundry. Here an attempt is made cost cutback of castings in radiographic test. There are many defects which can be identified through radiographic test and these defects are reduced or remedied by means of welding. This study focuses about the cost reduction of castings by means of "Total quality management tools".

“…Trial begins with pattern making, mould box preparation, pouring, solidification, shake out and cleaning. [12,13] A standard size mould box of dimension 300mm × 300mm × 160mm was used as taken in simulation study. The mould cavity was to be prepared in two parts, cope, the upper part and drag, the lower part as mentioned in the cylindrical casting section.…”

The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It directly affects the production cycle time, internal quality of castings and material utilization (yield). The process of casting solidification is complex in nature and the simulation of such process is required in industry before it is actually undertaken. The volumetric contraction accompanying solidification of molten metal manifests in defects like shrinkage cavity, porosity, and sink. These defects can be minimized by an intelligent methoding and simulation using casting software. In this paper, an attempt has been made to redesign and develop a casting free from defects, in particular, shrinkage defect. The component taken for methoding and simulation study was subjected to high amount of shrinkage defects which was the major cause for the rejection in the foundry. It also was having very low yield as 45 % as per the foundry information. The component under study consists of square shaped (at top) plate having three perforations with diminishing height (at bottom) and subjected to multiple hot spot. Therefore, optimum location of feeder has been identified by carrying out various simulation trials. Proper feeding aids have helped in getting the hot spot completely shifted inside the feeder. Simulation based approach has helped in the improvement of the feedability index which represents yield of feeders and quality of casting (percentage of volume free from shrinkage porosity). The simulations results were compared with the experimental trial and the comparison was found to be in good agreement.

Solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. This paper attempts to study heat flow within the casting, as well as from the casting to the mould, and finally obtains the temperature history of all points inside the casting. The most important instant of time is when the hottest region inside the casting is solidifying. ANSYS software has been used to obtain the last solidifying region in the casting process by performing transient thermal analysis. Location of the hot spot predicted by software simulation showed good agreement with the experimental trial. It was also observed that the simulation of casting helps in obtaining optimum design of riser.
