Few Things That You Need to Consider During Part Design

It becomes very much important to consider which manufacturing process you’ll use to produce an aluminum part while you are on your way to design it. You will come across different methods for forming aluminum, and aluminum die casting is one such option that designers consider.

For many automotive, industrial, and telecommunications products, metal die casting is the method of preference. It can even be used to produce lighting and electrical and hydraulic components.

While designing the part for casting there are a few considerations that you need to take into account.

Firstly, the mold should be designed in a way so that the solidified aluminum part can easily come out. A parting line is a line where the two halves of the mold come apart and you must consider it in the early stages of die design.

The location of injection points is another important consideration. There is the possibility of designing the die with several injection points but only when the molten metal solidifies before reaching every crevice in the die. This even helps if cavities are included in the design as you can surround them with the help of aluminum and still can get the part when the mold is separated.

The thickness of the part’s walls needs to be considered by the metal die casting supplier. For a minimum wall thickness, there are no guidelines given and it is all because of recent technology developments, but walls that have consistent thickness are highly preferred.

Different Options for Machining and Finishing

Minimal machining is generally required by die-cast aluminum arts, and there are various options available for surface finishing. Die casting has a very good surface finish but there is still the possibility of having imperfections, like metal seams. But you can address a rough surface or other imperfections with the help of sanding, sandblasting, or orbital sanding.

To improve fatigue resistance, the cold working process of shot peening is used on die-cast aluminum. To the finished part you can also apply protective or decorative coating such as a powder coat. After casting a few other types, the metal die casting company makes use of modifications such as drill tapping.
