Castings
BCI Castings and Forgings
Types of Castings A. 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 then allowed to solidify. The solid casting is then ejected or broken out to complete the process. From very small to very large.
B. 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.
C. 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 cavity displacing the wax. Allows for high detail and dimensional accuracy. Generally small and medium size.

BCI Castings and Forgings
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).
BCI Castings and Forgings
Testing We can provide material certification for all castings: – Chemical analysis – Mechanical tests, including >Tensile strength/elongation >Hardness testing
We also provide Non Destructive Testing upon request: --Dye penetration --MPI --UT --X-ray

Forgings
BCI Castings and Forgings
Types of Forgings A. Impression Die Forgings > Pounds or presses metal between two dies that contain a precut profile of the desired part. From 0.1 to 27,000 kgs (a few ounces to 60,000 lbs).
B. Open Die Forgings >Pounds between flat dies with no precut profiles in the dies. Movement of the work piece is the key to this method. Shapes up to 91,000 kgs (200,000 lbs.) and 24 meters (80 feet)
C. Seamless Rolled Ring Forgings >Typically performed by punching a hole in a thick, round piece of metal (creating a donut shape), and then rolling and squeezing. Up to 9 meters (30 ft) diameter.
D. Cold Forgings >Typically for smaller parts > Including bending, cold drawing, cold heading, coining, extrusion, punching, etc BCI Castings and Forgings

BCI Castings and Forgings
Surface Heat-Treating • Flame hardening –
A process whereby a forging is exposed to an open flame and then quenched (cooled in oil, water or air)
• Induction hardening –
The localized surface heating of a forging by an electrically-heated induction coil
