Aluminum Enclosure Types Compared

When you pick an enclosure, you should know how each is made. Each type has its own way of being built. They are different in cost, strength, and how you use them.

Diecast Enclosure Overview

A diecast enclosure is made with melted aluminum. The hot metal gets pushed into a mold with high pressure. This makes shapes that are strong and detailed. These enclosures protect electronics from harm and bad weather. Diecast enclosures are good when you need to make many at once. The molds cost a lot at first, but each box costs less if you make a lot. You see these enclosures in tough places or when you need something very strong.

Tip: Diecast aluminum is stronger than most plastics and does not rust easily, so it is good for outdoor or factory use.

Extruded Enclosure Overview

Extruded enclosures start with hot aluminum pushed through a shaped hole. This makes a long piece with the same shape all the way. You can cut it to any size you want. Extruded enclosures are strong but not heavy. They fit in small spaces and are easy to change. You can add holes, vents, or screens by cutting the panels. These enclosures are great for things like Raspberry Pi cases or custom electronics.

Sheet Metal Enclosure Overview

Sheet metal enclosures use flat pieces of aluminum. Machines cut and bend the sheets to make a box or panel. This way works well for simple shapes. These enclosures are light and do not rust. Sheet metal enclosures are cheaper for small amounts and are easy to change fast. You see these enclosures in computers, control panels, or other electronics that need a simple cover.

• Aluminum is light and does not rust.
