Gravity Castings
AmTech International delivers high-quality gravity castings for demanding OEM and industrial applications. Our gravity casting process uses permanent molds and the force of gravity—rather than high pressure—to fill the die cavity with molten metal, resulting in strong, consistent, and cost-effective components.

Overview
Gravity Casting Capabilities
Gravity casting is a permanent mold casting process that uses gravity, rather than high pressure, to fill the mold cavity with molten metal. This technique is especially well-suited for non-ferrous, light alloy components, including aluminum and zinc-based parts.
As a gravity casting manufacturer, AmTech International offers a cost-effective solution that does not require large-scale machinery. The process allows for precise control, resulting in strong, high-quality parts with superior surface finishes and improved mechanical properties compared to sand casting.
Gravity casting is ideal for producing mid- to high-volume runs of small to medium-sized parts. It is particularly effective for components with wall thicknesses greater than those achieved by high-pressure die casting, yet thinner and more refined than typical sand cast parts.
