Gravity die casting is a form of die casting which allows creating medium- and high-volume parts. This process is often referred to as "permanent mold casting." This process is considered for parts that are slightly heavier, larger in size, and have higher structural requirements . One can get pretty good repeatability from this process.
Gravity die casting is a versatile and effective means of quickly creating parts. Molten metal is poured into mold cavity. This method allows a single set of dies to be reused indefinitely to produce the same part. This is fortunate because the cost of the metal dies and casting machinery can be high. Gravity die castings are desirable because of their excellent surface finish and strength.
This technique is the perfect solution for those in need of quick turnaround and mass production. The parts produced via this method tend to be thinner than those produced by sand casting.
For manufacturers requiring a high volume of parts, gravity die casting is one of the best options available. It allows for reliable, repeatable parts that provide consistent quality as well as a broad selection of different metal alloys to choose from. Aluminum gravity die casting is one of the most popular and versatile choices for manufacturers needing strength, conductivity, thin walls, low weight, corrosion resistance and good mechanical properties. It is also a relatively affordable alloy to choose.
