Castings

BCI Castings and Forgings

Types of CastingsA. 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

Most common materials

• Grey Iron Castings• Malleable Iron Castings• Ductile Iron Castings• Steel & Stainless Steel Castings• Copper Castings• Bronze Castings• Brass Castings• Aluminum Castings

BCI Castings and Forgings

Malleable, Grey and Ductile Iron

• We use black and green sand molding, aluminum molding, 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 ASTM grades; for lower

quantity orders, conversion to

Chinese GB or Japanese JIS standards

is often necessary.)

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

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

BCI Castings and Forgings

Testing

We provide material certification for all forgings in:– Chemical analysis– Mechanical tests, including

>Tensile strength/elongation >Hardness testing

We also provide Non Destructive Testing upon request: --Dye penetration --MPI --UT --X-ray

BCI Castings and Forgings

Confidentiality

• We aggressively protect your intellectual property– We have NDAs will all partner foundries– We separate parts when possible to

conceal designs

BCI Castings and Forgings

Getting Started

• BCI signs NDA agreement• Customer provides drawings and specs

– Including quantity/delivery requirements

• BCI quotes• If acceptable, customer places order with BCI• BCI opens tooling• BCI provides sample casting/forging for

testing• If approved, BCI proceeds to production
