ABSTRACT Casting simulation has become a powerful tool to visualize mould filling, solidification and cooling, and to predict the location of internal defects such as shrinkage porosity, sand inclusions, and cold shuts. It can be used for troubleshooting existing castings, and for developing new castings without shop-floor trials. This paper describes the benefits of casting […]
CONCLUSION Knowledge of casting defects and causes is essential to managing casting quality. You should set clear defect tolerances and quality expectations with your suppliers before production to help them understand your quality standards. Defect tolerance can vary between products and types of casting defects. Determining your tolerance for these casting defects can help your […]
Present Cost Revised Cost Steel Scrap Rate = 107/Kg Quantity of Steel Scrap = 120kg Quantity of Scrap = 240 kg Cost of Scrap (120×107) = Rs12840 Cost of Scrap used (240×107) = Rs25680 Quantity of Swarf = 120 kg Ferrosilicon used in one heat = 1.750 kg Cost of Swarf (120×80) = Rs9600 Rate […]
ABSTRACT Quality can be perceived in accordance with requirements, costumer needs. It, in returns, implicates necessity of verification of this accordance, i.e. quality inspection. And that means how, on the ground of this inspection, to improve quality of articles and services. To speak about possible usage of repairing methods in firm, it is necessary to […]
Abstract Casting has various processes like Pre casting Processes, pattern making, core making, molding and mold assembly making, Casting Processes, furnace charging, melting, holding and pouring, and Post casting Processes, shakeout, inspection and dispatch etc. In India there are many foundry have followed conventional and manual operations. Today’s competitive environment has, lower manufacturing cost, more […]
Abstract In traditional technologies of casting moulds and core production on the basis of high-silica sands with binding agent addition, the reclamation consists mainly of a sand recovery and very seldom of a sand and bentonite recovery. Analysis of data from several countries indicates that from 600 to 1200 kg of fresh sand is used […]
Abstract Due to the presence of harmful substances in resins those mould sands may be hazardous to the natural environment and workers. The general assessment of harmfulness of sands used for molds and cores encompasses 2 basic points: emission of hazardous substances during processes of preparing sands, pouring mold with liquid metals (high temperatures), cooling […]

So if Business is to be carried forward, one has to work for Profit, otherwise the Business may be moving forward towards closure! No matter what the business did in the past, it is the present which counts. Main objective of a […]
Abstract Foundry is the main manufacturing methods for producing castings which are the basic material for any type of production. The casting obtained from the foundries are fed through various machining and manufacturing process for producing different type of components needed for many type Automobile, Industrial, Consumable and commercial products. It is an ancient manufacturing […]
Abstract Foundry industry is one of the major industries where castings are produced. 70% components of any automobile are produced with casting process. To produce such intricate shape hollow components cores are required which are produced in core shop. Cores are produced with different processes. In manual core making(MCM) process cores are produced manually and […]
Abstract Casting production is considered as one of the main factors influencing the development of the world economy. The state of art and foresight of the world’s casting production is discussed in the paper on the basis of the latest statistical data. The progress gained during the last few years in foundry engineering is shown […]
ADVANTAGES OF INDUCTION FURNACE: Induction furnaces offer certain advantages over other furnace systems. They include: Higher Yield. The absence of combustion sources reduces oxidation losses that can be significant in production economics. Faster Startup. Full power from the power supply is available, instantaneously, thus reducing the time to reach working temperature. Cold charge-to-tap times […]
