Things to Consider When Casting

There are numerous factors that need to be considered to ensure proper size, shape and integrity of the final component. Some of these factors include: 

• Type of material: each metal and casting material retains specific characteristics (hardness, melting point, density, etc.) that will affect the casting process.

• Cooling rate: This factor depends largely on the type of material from which you craft the mold. Proper cooling is necessary to minimize gas porosity and other negative properties that can result from a fast cooling rate.

• Shrinkage: As castings cool, they shrink. To ensure proper component size and integrity, you can utilize risers to feed additional molten metal into the cavity. An oversized mold may also be useful in some applications.
