NEWS CORNER
US Aluminum Castings adds capacity to machine shop
US Aluminum Castings, Entiat, Wash., according to
latest report, has purchased and received a new horizontal
CNC mill that will increase the company’s machine shop
capacity by 30%. To which media sources informed that,
US Aluminum’s machine shop produces parts in the
permanent mold and also offers heat treating, powder coating
and assembly has brought in additional machining capacity
to answer the growth it has seen across all of the end use
markets it serves.
Great Lakes Castings certified Elite by customer
Gray iron caster Great Lakes Castings LLC, Ludington,
Mich., recently was certified by customer Armstrong
International Inc., Three Rivers, Mich., as an “Elite Vendor,”
according to the latest media report. To which sources said,
“This is a distinct recognition and very few metalcasting
facilities make this grade, and Great Lakes earned it by
consistently delivering quality products on time.”
IFGL Refractories eyes overseas acquisition
According to a recent news, IFGL Refractories is
planning overseas acquisitions to expand its operations in
emerging markets. To which Pradeep Bajoria, director and
chief executive of IFGL, informed the press that “We are
in talks with some companies from South America, CIS and
Europe. We are looking at companies with substantial size
of more than $50 million.”
World’s largest blast furnace launched with
advanced magneco/metrel technology
Magneco/Metrel, Inc. recently announced that the
world’s largest blast furnace has begun production following
the installation of nearly 2,500 tons of its innovative Metpump
refractories. To which media sources informed that the silicabonded
pumpable refractories provide lining for the new
5,500-cubic-meter working volume furnace, operated by
Shougang Jing Tang United Iron and Steel, Ltd. in Caofeidan
TECHNOLOGY FOCUS
Indian Foundry sector to surge with auto sector growth
The recession, according to the industry experts affected
the foundry sector much later at the time, in September 2008,
when actually the global recession started resulting in the
collapse of the world economy, did not affect the exports of
casting in a major way, primarily because of the on going
projects in the Middle East and Europe rolled on till the end
of the year.
Chinese foundry industry is all likely to grow big
Post recession China’s economy has grabbed the attention
of the world economic exponents in a major way, the reason
for this being the economic activity in China has seen a big
rebound with the rise in its infrastructure work and a robust
economic growth as a result of various stimulus packages and
that it’s the Chinese demand that has become the sole factor
for actually measuring the true potential of the revival factor
among the developing nations.
CASE STUDY
Process optimization of a die casting tool Case study : aluminum table base
Optimization of die casting tools is becoming
more important to meet the customer quality
requirements and, at the same time, managing
production costs. The more complex the casting
part, the more demanding is the tool design and
the more difficult it is to reach an optimal layout.
SPECIAL COVERAGE
Near-Net-Shape Manufacturing of Austempered Ductile Iron (ADI) Components
Near Net Shape (NNS) manufacturing produces the engineering components closer to its final specification in single stage or minimum
number of stages. ADI process technology is one of the NNS manufacturing technologies, currently being followed by the industries for
manufacturing of engineering components at competitive price. Austempered Ductile Iron is a new class of engineering material which is
being manufactured from high quality Ductile Iron through austempering process. ADI castings provide a unique combination of high
strength and toughness coupled with superior wear resistance properties.
EDITOR'S COMMENT
Implementation of new & innovative IT-based foundry technology is the need of the hour
Now it has been ten years down the line in the new millennium and the entire world is
wired up like never before. IT has taken into its grip all the conception so far as
manufacturing technology is concerned. IT-enabled design, manufacturing process and
delivery of cast products is no longer a luxury but a bare necessity today and that is too
in a competitive world like this. A recent survey of over 200 Indian foundries shows that
on an average, foundries using CAD and simulation report 30% faster casting development
and 50% less rejection than others.
TECHNOLOGY/PROCESS REVIEW
Investigation of Sound Casting in SEM Microstructure for Traditional Investment Casting in Eastern India
The Dokra-men have been practising the traditional investment casting
for millennium in Eastern India to manufacture domestic brass or bronze
items1. This is a unique type of investment casting process, known as
Dokra....(2). Most of the Dokra-men are not well-known to the sound castings.
They are trying to develop sound casting, but fail due to some unknown
parameter. One of the investigations is to analyse the microstructure along
with EDX and Line-Scan. The sound casting is reflected on studies of
micrograph structure. We may detect phase, bonding structure, porosity,
foreign particle and hardness in the microstructure. The entire above are
directly or indirectly related to the mechanical strength and durability. Good
mechanical properties of casting, is called sound casting. Characteristic of
mechanical properties with the related SEU microstructure of casting is the
object of this paper.
High-Level Sand Reclamation for Sodium Silicate and Alkaline Phenolic-Based Sands†
Historically, due to the chemical nature of these two binders, it has proven difficult and costly to attain significant levels of sand reclamation.
However, due to the recent introduction of a novel method of sand conditioning, it has been proved that upto 90% of the sand can be re-used
in the foundry without compromising on casting quality or production.
Cast Nonferrous: Zinc-Aluminum Foundry Alloys
Zinc-Aluminum Foundry Alloys 8, 12 and 27 comprise a
new family of zinc casting alloys that have proven themselves in
a wide variety of demanding applications. They are engineering
materials well suited to applications requiring high as-cast strength,
hardness and wear resistance. These three alloys offer designers
and casting specifiers viable, cost-effective alternatives for their
component requirements.
New Material A Cast Iron Featuring Improved Elongation for Better Equipment Performance
Producing a material combining a strength of the order
of 800 to 1000 MPa with good ductility is still tricky, especially
for parts having a large section. In the case of the bainitic cast
irons produced by step quenching, or ADI. metallurgists attempt
to attain the best possible characteristics by working on the
heat treatment. By contrast, the project developed by CTIF and
presented here attempts to achieve this combination of properties,
without recourse to heat treatments, by optimising the production
and chemical formulation of the material; this has a definite
economic advantage over the conventional solution.
Filters help eliminate dross in copper-base alloy castings
Research on various copper-base alloys using three types
of ceramic filters shows a dramatic reduction of dross inclusions
in castings. In both ferrous and non-ferrous metalcasting,
employing the appropriate gating system can minimize the
entrapment of nonmetallic inclusions. In many cases, however,
the use of filters in those gating systems eliminates even finer
inclusions, while improving the appearance, quality and
properties of the castings.
Magnesium Alloy Castings makes a major breakthrough as aerospace component
Magnesium alloy castings can be produced by nearly all
of the conventional casting methods, namely, sand, permanent
and semi permanent mold and shell, investment, and diecasting.
The choice of a casting method for a particular part
depends upon factors such as the configuration of the proposed
design, the application, the properties required, the total number
of castings required, and the properties of the alloy. Magnesium
castings of all types have found use in many commercial
applications, especially where their lightness and rigidity are
a major advantage, such as for chain saw bodies, computer
components, camera bodies, and certain portable tools and
equipment. Magnesium alloy sand castings of late are being
extensively in aerospace components.
