Types of Castings
! Gravity Castings(Sand mold, permanent aluminum mold)" The process by which molten metal is poured into a mold,
which contains a hollow cavity of the desired shape, and thenallowed to solidify.
" The solid casting is then ejected or broken out to complete theprocess.
" From very small to very large.
! Die Castings" The process of forcing molten metal under high pressure into
mold cavities (which are machined into dies).
" Small to medium in size; capable of high detail.
!Investment Castings--(Lost Wax/Loss Foam)" The process of forming wax (or foam) into a shape, covering the
shape with sand and then pouring molten metal into the cavitydisplacing the wax.
" Allows for high detail and dimensional accuracy.
" Generally small and medium size.

Malleable, Grey and Ductile Iron
! We use black and green sand molding, aluminummolding, and lost-wax/lost foam methods
! Size from 0.1 kg to 8000 kg (3.5 oz to 9 tons)
! All ASTM grades available
! For higher quantity orders BCI can directly cast ASTMgrades; for lower quantity orders, conversion toChinese GB or Japanese JIS standards is oftennecessary.)

Heat-Treating
! Normalizing" Reduces internal stresses and improves crystalline structure by application of
heat, maintaining temperature for appropriate duration, then slow cooling.
! Water and oil quenching" Rapid cooling from elevated temperature to increase hardness and strength.
Often followed by tempering to restore some ductility (toughness).
! Tempering" Reduces hardness and increases toughness by application of heat, maintaining
for appropriate duration, then controlled cooling.
! Surface Hardening" Increases surface hardness of wear parts by engineered application of heat by
flame (flame hardening) or induction coils (induction hardening).
