- 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 casting.
- The people who work
in the foundry making molds and pouring castings traditionally worked
moving sand extensively, and thus were affectionately called
sandrats.
- Iron and steel parts
are typically formed by the sand casting method; aluminum and other
non-ferrous metals are typically formed by the die cast method.
Sand
casting utilizes a pattern molded from a mixture of sand, clay, and
binder often called "green sands" and Die casting is often used to mold
smaller metal parts such as transmission or compressor
casings.
- A general process at
a green sand foundry shows two main streams: one for metal and another
for sand. Metal goes from stockyard, through melting, holding and
pouring. Sand goes through green sand preparation, core manufacture up
to moulding lines. There metal and sand get together when molten metal
is poured and allowed to solidify and cool, in order to shape it as a
casting.
- The fly ash could be
utilized as a replacement and filler in foundry sands used for molds and
core production. The fly ash was more suitable than ferrous applications
due to the high pouring temperature. All types of ash were suitable for
molds and core making for many non ferrous metals such as, Cu-, Al- and
Zn- based alloys.
- Phenol is used to
produce Phenol formaldehyde condensation resins, which are used in many
different applications, such as: Plywood, particle board and insulation
materials for the construction industry, Moulds in the foundry industry,
Adhesives, Furniture manufacturing.
- Foundry sand is high
quality silica sand that is a byproduct from the production of both
ferrous and nonferrous metal castings.
- Metal foundries use
large amounts of sand as part of the metal casting process. Foundries
successfully recycle and reuse the sand many times in a foundry. When
the sand can no longer be reused in the foundry, it is removed from the
foundry and is termed “foundry sand.”
- 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.
- The largest volume
of foundry sand is used in geotechnical applications, such as
embankments, site development fills and road bases.
- The 3,000 foundries
in the United States generate 6 million to 10 million tons of foundry
sand per year.
- Currently,
approximately 500,000 to 700,000 tons of foundry sand are used annually
in engineering applications.
- India’s ability to
produce almost any type of casting at any quality level, at a
competitive price, together with its annual capacity of 7.5 million
metric tons, makes it a world leading outsourcing destination for
casting products.
