Modernisation and Technology Upgradation in
Foundry Industry booming with
The foundry industry on a global scale is surely on a booming path.
With upcoming augmentation plans and a touch of technology, it won't
be a surprising sight to witness the related sector to on a brighter forum.
Additionally, with the onset of series of technological fairs and expert
meets, the foundry sector is gaining new highs.
Modernisation and Technology Upgradation in
Foundry industry has a dominant influence on the economy
of any country because metal-casting is the primary step for
a large number of sub-sequential metal shaping operations. It
is the basic manufacturing industry whose products are used
in almost all aspects of modern industrial economy. The growth
of engineering industries generally depends on the casting
industry. Founding is one of the most important manufacturing
processes for producing metallic engineering components.
Accuride Corp., Monterrey- first to offer aluminium wheels
Accuride Corp. stands as the first
company to offer aluminium wheels
from its Monterrey plant, Mexico. This
is exercised post shifting of a
machining line to that operation from
its Erie, PA, plant, previously in 2011.
Aerocast set to augment output
Aerocast Inc., Mesa, Ariz., fabricating non-ferrous sand
castings has secured a loan of approximately $2 million to
augment its output. The company opined it has received
$1,450,000 of the original loan and is in discussions with the
same lender for additional advances.

compacted graphite iron (CGI) production, following an order
for the developer’s Mini-System 3000.
General Motors to invest in Saginaw
Metal Casting Operations
General Motors (GM) announced that it will invest
around $215 million in its Saginaw Metal Casting Operations,
Saginaw, Mich., to update the plant for production of future
engine blocks and heads.
Optimisation of Casting Weight Using Box-Behnken
Design in Foundry Industry for Energy Conservation
The quality and weight of castings from green sand mould is influenced significantly by process parameters like moisture content, bentonite, coal
dust and mixing time. In the present study, experiments were conducted to measure the casting weight by varying the process parameters. The
corresponding green sand properties viz., green compression strength, permeability, compactibility and mould hardness were measured. Regression
analysis was carried out on the experimental data collected based on statistical design of experiments (DOE) to establish the input-output relationship
of the process. Box-Behnken design of response surface methodology is used to develop the model for predicting and optimising the casting weight.
Analysis of variance (ANOVA) was performed to test the statistical adequacy of the model. The results indicated that moisture content and bentonite
determined the weight of castings. The experimental values were in good agreement with the predicted values.
Parametric Influence on Melting Rate in Rotary Furnace Using Bio-Fuels - A Parametric
Study Using Taguchi Method
The paper aims to find an efficient way to determine influential factor on the response factor by reducing process or product variability and also
minimising product error by using a relatively small number of experiment and to achieve superior quality product. An experimental investigation
into the process parameter is done to have a robust design method for identifying process parameters having the major influence on melting rate
in rotary furnace. Minimum number of experiments are planned using Taguchi Method. The variation of several parameters and the interaction
between parameters are investigated using orthogonal array technique. An experimental investigation into the process parameter effects using
Jatropha as fuel is presented to determine this influence for quality castings. Rotary furnace involves several critical parameters like flame
temperature, preheat air temperature, rotational speed of the furnace, excess air percentage, melting time, fuel consumption and melting rate of
the molten metal which should be controlled throughout the melting process to produce homogeneous casting of high quality. The relative effect
of these variables on melting rate while experimenting using Jatropha oil as fuel is quite complex. Partial factorial design using L9 (34) orthogonal
array is used to study the effect of these parameters on melting rate. Having the knowledge of interrelationship between these variables, the
manufacturer would be able to select the optimum input parameters which would yield ideal melting rate for producing quality castings.
