Aluminum Alloy Casting Manufacturing Process and Characteristics
Aluminum alloy castings refer to equipment components made from pure aluminum or aluminum alloys through casting processes. The manufacturing processes for aluminum alloy castings mainly include the following two methods:
Sand Casting: A casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be produced using sand casting. This process offers strong adaptability and low cost. For materials with poor plasticity, such as cast iron, sand casting is the only forming process for manufacturing parts or blanks. However, it has a high rejection rate, low surface quality, and poor working conditions.
Investment Casting: Typically refers to a casting scheme where a pattern is made from fusible material, coated with multiple layers of refractory material to form a shell mold. The pattern is then melted and removed from the shell mold, resulting in a casting mold without a parting line. After high-temperature baking, the mold is ready for sand pouring and casting. This method is often called "lost-wax casting."
The characteristics of aluminum alloy castings vary depending on the production process. For example, castings produced by sand casting have higher strength, dimensions, and appearance compared to those made by other casting processes, but their surface smoothness is not high, and they exhibit lower product density and slightly inferior strength. When selecting a production process, the choice is primarily based on the wall thickness of the workpiece. Products with a wall thickness greater than 8mm can be produced using gravity casting processes.
