SIZE

In the 1/2 lb. to 20 lb. range, but higher weights of 100 lbs are possible.

SURFACE FINISH

Normally in the 125-300 rms range.

WALL THICKNESS

A wall thickness of .060" can be obtained for certain castings and .125" is practical for castings up to 14" in any one direction.

GENERAL TOLERANCES

    Up through 1”     ± .005”

    Over 1”                ± .015 + ±.002 in/in.

                                   over 1"

CORED HOLES

A cored opening less than 1/4". in diameter usually is not practical.  In some specific cases, however, holes of 1/8" diameter or even smaller are possible if formed by stationary core pins.

ALLOYS

Included among the alloys that may be cast: A206, 319, 333, 356, 360, 380, 518

DRAFT

Typically 2-4 degrees draft.

FILLETS

Adequate fillets at all wall intersections and at all angles where bosses or depressions are involved are almost mandatory for the proper flow of metal.  Sharp angles weaken the castings and may cause cracks during solidification or removal from mold. 

MECHANICAL PROPERTIES

Tensile-Yield-Elongation – as per the appropriate commercial and military specifications. 

DELIVERY

Samples 4 to 12 weeks.  Production 2 to 6 weeks after approval. 

TYPICAL APPLICATIONS

Major uses include piston and other functional parts of internal combustions engines, marine engine and structural parts, textile machine parts, motor housings, portable tool parts, fan cases, medical related equipment.
