Gravity Castings & Permanent Mold Castings

Permanent mold or gravity castings are a metal casting process offered by Connor Corporation that is characterized by pouring molten metal into a tool cavity under the force of gravity. The tool cavity is formed by two steel die halves, which have been machined into shape. Most gravity castings are made from non-ferrous metals, such as aluminum alloys.

Understanding the Benefits

A primary advantage of this process for automotive castings and industrial castings is the ability to produce sizeable detailed aluminum parts at medium volumes. Many times, net shape parts with little or no secondary processes can be produced. The tools are reusable so gravity casting can produce economical part prices for medium volume programs. Typical volumes start at 10,000/year to 100,000/year. Machining parts and forging have their advantages, but the costs are often higher with these processes.
