No, aluminum cannot be injection molded in the conventional sense of plastic injection molding, where molten material is injected into a mold to form parts.

Standard injection molding applies primarily to plastics (thermoplastics or thermosets), and sometimes to other materials via specialized variants. 

Specialized Processes for Aluminum

There are niche processes that resemble injection molding for aluminum:

1.Metal Injection Molding (MIM) for aluminum — This uses fine aluminum powder mixed with binders, injected like plastic, then debound and sintered. It's feasible but not common (more typical for steels, titanium, etc.), and suited only for small, complex parts with lower density/strength than cast aluminum.

2.Thixomolding or semi-solid processing — Primarily for magnesium; aluminum's reactivity makes it challenging and uncommon.

Common Misconceptions

Searches for "aluminum injection molding" often refer to using aluminum to make the mold (tooling) for plastic injection molding. Aluminum molds are cheaper and faster to machine than steel, ideal for prototyping or low-volume runs (thousands of parts), but less durable for high-volume production.In summary, for producing aluminum parts, die casting is the standard, efficient method for most applications (e.g., automotive, consumer goods). Injection molding is not used for aluminum itself.
