Abstract:
Foundry has been there always
in the basis of all kinds of industry for
over hundreds of years suppcrrting the
progress of technology and convenience
of human life.
Today, we are surrounded by cast
metal products such as automobile
engine, components of under-carriage,
agricultural machine parts, various water
pump, pipe fitting, weaving machine
parts, manhole cover, ashtrays and
even ornamental artistic items. Cast
products around us are really countless.
There are many different ways to
produce these varieties of castings.
Most of them were started with a primitive,
manual method several hundred
years ago and gradually mechanized.
Under the pressure of high labour
cost in the recent years, the only way
to survive is mechanization and automation.
