How Is Aluminum Casting Done?
Aluminum casting creation encompasses several key steps that transform raw materials into precision-engineered components. At the outset, high-quality aluminum ingots or scrap are melted in a furnace, reaching temperatures around 1,200°F to 1,400°F. Once molten, the aluminum is often treated to remove contaminants, ensuring exceptional casting quality.
Following this, the liquid aluminum is dispensed into a previously prepared mold, which can be fabricated from various materials relative to the required casting method. After the aluminum occupies the mold, it is given time to cool and solidify, assuming the shape of the mold.
After cooling, the casting is released from the mold and enters finishing processes, including machining, to reach the necessary tolerances and surface finishes. Finally, the cast component is checked for quality assurance, guaranteeing it adheres to industry standards before being delivered for use in diverse applications.
Well-Known Aluminum Casting Methods: Sand, Die, and Additional Options
The aluminum casting sector employs multiple processes to attain the desired shapes and properties.
