AIM (aluminum alloy powder injection molding) process introduction, what is AIM

Aluminum alloy injection molding (AIM) is a technology used to form aluminum alloy parts. It is similar to metal powder injection molding (MIM) and is a branch of powder injection molding (PIM) technology. AIM is developed from injection molding technology and is currently the fastest-growing and most widely used aluminum alloy parts processing technology in the world.

The process of AIM involves uniformly mixing aluminum powder and a binder, then granulating the mixture through a granulator. The granulated material is then injected into a mold cavity to achieve the desired shape. The mixed melt has good fluidity after heating, which facilitates the injection process and ensures the density uniformity of the product. The formed products need to undergo degreasing and sintering in a sintering furnace, and may require post-treatment.

AIM technology is suitable for producing large quantities of parts with complex shapes, including three-dimensional shapes. The products produced using AIM do not require extensive machining or only require minimal machining, which significantly reduces production costs and improves work efficiency. The injection process ensures high precision and uniform density in the formed products.

AIM can process and produce parts with extremely complex shapes, with the smallest part weighing as little as 0.1g. The products have a uniform structure, high precision, and smooth surface. They also exhibit stable quality and high production efficiency, making AIM suitable for mass production. Due to its advantages in precision and work efficiency, AIM has been widely applied in industries such as navigation, aviation, machinery, automobiles, and precision instruments. It is the fastest-growing aluminum alloy processing technology in the world and has gained popularity in various industries.
