SIZE

Ounces to several pounds.

SURFACE FINISH

Normally in the 25-125 rms range, with 63 rms as the standard. 

WALL THICKNESS

Maximum mechanical properties are obtained in die castings when the wall thickness is in the range of .078 to .150 inches.  The minimum wall thickness that is castable will depend upon several factors, including configuration of the casting, position of the gate, metal flow in the die, and the projected area of the die cast part. 

GENERAL TOLERANCES

Non-Critical Dimensions

    Up through 1”     ± .005”

    Over 1”               ± .005 + ±.0015

                                  in./in.  over 1”

Critical Dimensions

     Up through 1”    ± .003”

     Over 1”              ± .003” + ±.001

                                  in./in.  over 1”

ALLOYS

Aluminum, zinc, and magnesium are the most common alloys cast.

DRAFT

Many parts made in the die cast process (particularly with magnesium) may be designed with little or no draft.  Consult foundry for draft requirements. 

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 8 to 12 weeks.  Production 4 to 6 weeks after approval. 

TYPICAL APPLICATIONS

A variety of uses within the automotive and commercial industries.  Lawn and garden, computer, food equipment, pump, hand power tools, and appliance industry are among the users of die castings.
