Aluminum Die Casing Parts

Aluminum die casting is a manufacturing process that produces accurate, defined, smooth, or textured-surface aluminum casting parts. The aluminum dies casting process is completed by forcing molten aluminum into a mold through high pressure. Aluminum dies casting parts are corrosion resistant, and highly conductive. They have good stiffness and strength-to-weight ratio. The aluminum dies casting process allows for the production of aluminum casting parts in a high volume fast. Compared to other casting processes, aluminum die casting parts are more cost-effective.

What Are The Advantages Of Aluminum?

Aluminum is lightweight. It has high dimensional stability for parts with complex geometries and thin walls. Aluminum is corrosion-resistant. It has good mechanical properties and high thermal and electrical conductivity. So, aluminum is a great alloy for die casting. Low-density aluminum is important to the aluminum die-casting industry. The aluminum dies casting process retains a durable strength under high temperatures. The aluminum dies casting process needs cold chamber machines. The molten aluminum is contained in an open pot which is placed into a furnace and melted to a certain temperature. The open holding pot is separate from the aluminum die-casting machines. And the molten aluminum is ladled for each casting as the high temperature may damage the pumping system. Cool chamber castings need higher pressure than hot chamber die casting.

What Are The Advantages Of The Die-Casting Process?

Compared to other metal forming processes, aluminum casting offers many advantages so it is a great choice to create aluminum parts. The main advantages of aluminum die casting is its ability to create parts in complex shapes which extrusion or cnc machining can not do. For example, complex automotive die-casting parts like transmissions and engine blocks. Complexity and tight tolerances can be achieved consistently by the aluminum die casting process. The die casting process is able to produce parts with textured or small surfaces. It can produce small and large parts.

The Most Common Casting Aluminum Alloys

The most commonly used aluminum alloys for die casting are A380, 383, B390, A413, A360, and CC401. A360 is good corrosion resistant, pressure tight, and has good fluidity when molten. B390 is wear-resistant and hard. B390 has the lowest ductility of all casting materials. It is widely used to produce automotive engine blocks. A380 provides a good combination of casting and product properties. Is commonly used for casting a wide range of products.

Casting Finishing Available

Casting aluminum parts need little machining. There are several options available for aluminum casting part surface finishing. Aluminum die casting has a good surface finish by casting standards. There are still some imperfections such as metal seams which the mold halves meet. Sanding, sandblasting or orbital sanding can improve a sough surface and other imperfections.
