Aluminum alloy gravity casting molds refer to the gravity casting process where molten metal is poured into molds under the force of Earth's gravity, also known as gravity casting. Broadly speaking, gravity casting encompasses sand casting, metal casting, investment casting, lost foam casting, clay casting, and more. Narrowly, gravity casting primarily refers to metal casting, hence the broad category has many variations.
Aluminum alloy gravity casting die-casting molds are the dies used in die-casting forging machines to cast metal parts and complete the die-casting process. The basic process of die-casting is as follows: first, molten metal is cast at a low or high speed and filled into the mold cavity with a movable cavity surface. As the molten metal cools, compression and forging not only eliminate shrinkage and porosity defects in the billet but also disrupt the internal structure of the billet in the forging state. The mechanical properties of the billet's stress response are significantly improved.
Aluminum Alloy Gravity Die Casting Low Pressure Die Casting Molding - Low pressure die casting involves placing the mold above a sealed crucible, introducing compressed air into the crucible, creating a low pressure (0.06~0.15MPa) on the surface of the molten metal. The molten metal rises from the outlet, fills the mold, and controls the casting process through aggregation. This casting method boasts advantages such as good feeding, fine casting structure, simple casting process, no outlet, and a high metal recovery rate of up to 95%. It is environmentally friendly and easily automated. However, it is costly in terms of equipment and has a low output power. Generally used for casting non-ferrous alloys. Also known as external low pressure casting.
Aluminum alloy gravity casting is widely used in industries such as the automotive industry, internal combustion engine production, motorcycle manufacturing, electrical machinery manufacturing, gasoline pump production, transmission machinery manufacturing, landscaping, power construction, and architectural decoration. Aluminum die casting can be used to produce auto parts, auto engine components, engine cylinders, gasoline engine cylinder heads, valve rockers, valve supports, power components, motor end caps, casting shells, pump housings, architectural components, decorative parts, guardrail components, and aluminum wheels, among others.
