What is Cast Aluminum Patio Furniture?
Cast aluminum describes a process of creating cast components formed by the solidification of molten aluminum poured into a mold. Cast aluminum is also referred to as “solid cast aluminum” The above process is divided to “Sand Cast” and “Die Cast”
Note that cast aluminum furniture is different than your average aluminum furniture. Unlike tubular aluminum frame, which is hollow and bent into shape, cast aluminum is so called solid aluminum.
This casting method makes it easy to achieve exceptionally detailed surface textures of all kinds. Popular designs include over-elaborate shapes that look like wrought iron work as well as sleek, modern lines, so you will likely be able to find cast aluminum furniture in a style that you will enjoy.
Sand Casting is a process that starts with a pattern that is a silicon model of the finished casting. The pattern pressed into a fine sand mixture to form the mold into which the aluminum is poured. Typically sand cast parts come with ticker wall. Sand casting is slow process capable intricate designs or when a very large casting is required. Example: Large cast aluminum table top.
Characteristic of Sand cast aluminum is smooth grainy light textural and consistent looking finish. The texture can improve the aesthetics of furniture or décor. The item with a granular finish or imperfections that may enhance antique-like qualities.
Most sand cast aluminum made furniture are design in traditional style however it is not a rule and contemporary cast aluminum designs are implemented.
Die cast describe a process where “molten” (aluminum in our case) is forced into a die under high pressure in to the mold. “die” it is a steel mold created to shape the product that will be made.
When the metal solidifies it is removed from the mold and a product has been manufactured. The steel mold can be closed and prepared for the next “shot,” which allows it to be reused instantly.
Characteristic of Die cast aluminum is smooth perfect like finish with consistent thickness according to perfection of the die cast mold. It allows for more detail compering to Sand cast however it cannot used in production of large surfaces. Large table top for example can be produced in two or three smaller parts welded together to from one large table top. Do to precise control of the allowed thickness of the fast produced aluminum furniture made in die cast process are lighter and tend to have less strength then sand cast aluminum furniture.
