- A foundry is a
factory which produces metal castings from either
ferrous or non-ferrous alloys. Metals are turned into
parts by melting the metal into a liquid, pouring the
metal in a mold, and then removing the mold material or
- The most common metal
alloys produced are aluminum and cast iron. However,
other metals, such as steel, magnesium ,copper, tin, and
zinc, can be processed.
- The people who work
in the foundry making molds and pouring castings
traditionally worked moving sand extensively, and thus
were affectionately called sandrats.
- In a
foundry operation, molten metals are shaped into a variety of forms.
Iron and steel parts are typically formed by the sand casting method;
aluminum and other non-ferrous metals are typically formed by the die
- Sand casting utilizes a
pattern molded from a mixture of sand, clay, and binder (often called
"green sands").Molten metal is poured into this pattern, and allowed to
cool. During "shake out," the cooled cast part is then removed from the
now-waste sand mixture and proceeds to various processes including
machining and assembly. Examples of component parts include
the engine block and cylinder head, and CV joint.
- Die casting is often
used to mold smaller metal parts such as transmission or compressor
casings. The shape of the component part is forged in relief in a metal
pattern. Molten metal is poured into this die and allowed to cool. The
cast part is removed and to prevent sticking, a releasing agent is often
sprayed before the metal is poured. Examples of die casting include the
transmission case and various interior trim and component parts.
- Manufacturing techniques have been
developed over several decades that allow control over the macro &
microstructure of the materials to produce several important material
effects. Three forming techniques dominate – ribforming, rollerforming
and isopressing. Each gives different structural features in a crucible.
- Rib and rollerforming
techniques impart shearing effects on the material which orient the
graphite along a designated direction.
- Isopressing involves
relatively little shearing of the materials, producing a random
orientation of the structure. The orientation effect has a huge
influence on crucible behaviour. High levels of orientation promote
improved thermal shock and impact resistance.
key applications for Phenol and Acetone are in the production of
polycarbonate, plastics, phenolic
resins, synthetic fibres (such as nylon) and solvents. These products
are used in a diverse range of endmarkets, including the automotive,
construction, electronics and fibre industries.

foundry sand generated by metal casting foundries using sand containing
the sand binders or binder systems in their sand mold production
- Market the application of fly ash as
a base material substitution for foundry sands (FASAND mixture) to
produce iron castings for the automotive industry. Two types of fly
ashes were examined: the fly ash from the FirstEnergy Eastlake Plant
(USA) and, the fly ash from the Skawina Power Plant located in, Poland
from where the visiting professor working on the project is the Deputy
- The U.S. foundry industry is
characterized by a high degree of concentration and a large proportion
of small producers. The top 10 responding producers collectively
accounted for 32 percent, by quantity, of
the industry's total production.
- Approximately 50 percent of
responding producers have 100 or fewer production workers. An average
responding firm produced about 24,000 short tons of castings and
employed 184 production workers
