Introduction
Graphite molds play a crucial role in the Aluminum Extruders and Molten Aluminum industry.
Stability and Density: Graphite molds, regardless of the grade chosen, exhibit high stability and density. They do not warp, twist, or check when molten metal (such as aluminum) is introduced. This stability ensures accurate casting.
Thermal and Electrical Conductivity: Graphite molds are thermally and electrically conductive. This property is essential for efficient heat transfer during the casting process.
Resistance to Bending: Graphite molds are resistant to bending, maintaining their shape even under high temperatures and pressure. This stability contributes to precise casting results.
High Thermal and Chemical Resistance: Graphite molds withstand extreme temperatures and chemical environments. They can handle the demands of molten aluminum casting.
Graphite molds provide accuracy, stability, and durability, making them ideal for aluminum extrusion and casting processes. They prevent leaks and ensure high-quality castings in the industry.

The Application Details
1. Aluminum Extruders:
- Graphite molds are used for shaping aluminum extrusions. These molds help create precise profiles and dimensions during the extrusion process.
- Common applications include run-out plates, flight bars, canisters, sidewalls, special shapes, elements, seals, and flux/chill tubes.
2. Molten Aluminum:
- In the molten aluminum industry, graphite molds are essential for casting and shaping aluminum alloys.
- They are used for various purposes, including:
- Ingot molds: Used for solidifying molten aluminum into ingots.
- Continuous casting: Graphite molds enable continuous casting of aluminum, ensuring consistent quality.
- Pressure casting: Molten aluminum is forced into reusable metal dies using graphite molds.
- Centrifugal casting: Spinning molds create desired shapes by driving molten metal against the inner mold wall.
- Hot pressing dies: Used in pressure sintering of cemented carbide.
- Vacuum metallurgy: Graphite molds serve as insulation plates, furnace components, and more.
Graphite molds offer advantages such as accuracy, smooth surfaces, and reduced metal consumption, making them indispensable in these industries. Their ability to withstand high temperatures and unique properties make them a cost-effective solution for aluminum processing.
