For those who are well-versed in electrical applications, they are probably well-aware of the different types of enclosures. If you are somewhat new to the industry, it is normal to do some research and learn about enclosures and the different types available in the market.

In this article, we will be discussing the different types of enclosures. This should help you make informed decision when deciding on which type of enclosure is perfect for your project.

Some engineers use metal enclosures, and these can be quite expensive as well as affect the flexibility of the material. If you want economical enclosures, you can consider plastic, die-cast aluminum, steel, fiberglass, and aluminum sheet metal.

The material used for the enclosure usually dictates the application, customization, and budget of the customers for the project. Enclosures are not only used in the electrical industry, but it can also be used in other areas such as telecommunications, factories, as well as both indoor and outdoor controls that are exposed in corrosive environments.

What Are The Different Types Of Enclosures?

What Are the Different Types of Enclosures?

Die-Cast Aluminum Enclosures

Die-aast aluminum enclosures are lightweight, more rigid, and have better compression strength compared to plastic enclosures. This type of enclosure is used for different applications, such as housing electrical, electronic, hydraulic and pneumatic devices.

It is capable of providing adequate protection through the EMI shielding. Die-cast aluminum enclosures can be applied with powder coat finish and enhance the corrosion-resistant property of the product.

If you are searching for die-cast aluminum enclosures, make sure to check out SEI Castings. We can manufacture and customize your products according to your specifications.

Plastic Enclosures

Plastic is one of the materials that is the most cost-effective among the enclosures available on the market. Plastic enclosures are lightweight and make it easy to carry. There are a lot of compact devices that are packaged with plastic enclosures.

Plastic enclosures are used for applications based outdoors, in junction boxes, and in industrial controls. Sometimes plastic enclosures are the choice for instruments that are affected by metal and uses non-metallic fasteners and latches. It is a corrosion-resistant material and it can also be used for washdown environments.

Plastic Enclosures

This type of enclosure offers the same benefits as plastic enclosures. Fiberglass enclosures are corrosion-resistant, lightweight, and stronger than steel. It can be used in high-temperature operations, but the downside to it is that it costs a lot and uses expensive tools during the manufacturing process.

Steel Enclosures

Stainless steel enclosures are used to house electrical devices for commercial and industrial outdoor corrosive environments. This type of enclosure is corrosion-resistant, weatherproof, and can be wall or surface mounted depending on its application.

Sheet Metal Enclosures

Sheet metal enclosures provide different properties such as EMI shielding, heat dissipation, and compression strength that plastic enclosures do not have. Sheet metal enclosures can be quite expensive, especially if manufactured in low quantities, however, this type of enclosure is more durable and heavier than other types of enclosure.

Steel is not corrosion-resistant, so if you are searching for corrosion-resistant enclosures, you can choose die-cast aluminum enclosures, so make sure to contact SEI Castings for any inquiries about our products and services. Sheet metal enclosures can be customized based on the specifications of the product.
