If you are thinking of an aluminum enclosure for your subsequent project, you are possibly conscious of the many advantages this metal can offer. But did you also know that the metal shaping method of an aluminum enclosure can influence its uses and added benefits?

Diecasting and extrusion are two typically used metal shaping procedures that should be taken into consideration before deciding upon an aluminum enclosure. Within this post, we’ll talk about the pros and cons of each and every technique to make sure that you choose the proper aluminum enclosure for your application.


Die Casting vs. Metal Extrusion

Die casting is a highly distinctive procedure from metal extrusion. In die casting, molten metal is forcefully injected into a mold called a die. Dies could be made to kind incredibly complex shapes, including those with irregular cross sections.



Given its numerous desirable characteristics, an aluminum alloy is usually a prevalent option for higher-pressure diecasting. Blending aluminum with other metals can boost precise material properties, including strength and ductility, creating it appropriate for a wide array of indoor and outside applications.

As an illustration, diecast aluminum enclosures are frequently made use of to defend switchboards and meter cases in several industrial environments. With their all-natural amount of RFI/EMI shielding, diecast aluminum enclosures can also be located in numerous healthcare instruments, where eliminating EMI/RFI interference is essential.


Positive aspects

With molten metal forming the precise shape of the die, the diecasting process is perfect for those who require complicated components.

One more important advantage to diecasting is that it leads to thinner, lighter walls. In contrast to the extrusion manufacturing course of action, a thick solution isn’t necessary to undergo diecasting. The outcome is often a thin, lightweight aluminum enclosure with an eye-catching surface finish.



Its corrosion-resistance and EMI shielding properties make diecast aluminum enclosures a well-known option among design engineers. Nonetheless, there are some disadvantages to this manufacturing method. With its higher upfront expense, diecasting is more suitable for high-volume production. Porosity is yet another widespread problem related to diecasting and will be the outcome of air entrapment inside the metal dies.

Metal extrusion does have some positive aspects over die casting. When utilizing specific supplies, such as alloys made from aluminum, magnesium, and zinc, extruded parts have strength and rigidity values similar to die-cast components, but ductility could be more significant. Tooling expenses are frequently decreased for extrusion than for die casting. In the same way, die casting features a number of benefits more than extrusion. For 1, components that happen to be die cast have higher stiffness values – they’re much less elastic than extruded components. Die-cast is typically complete, such as surface textures and finishes, in just one particular step.

One of the most vital positive aspects of die casting is that it is not limited to making parts with uniform cross sections. Cross-sectional modifications or variations, holes, slots and any quantity of other style attributes need that pricey secondary machining services to be performed on extruded components. With die castings, all such options can be made directly into the mold for one-step manufacturing.
