Plastic Enclosures

Plastic enclosures are designed to house and protect sensitive electronic and electrical components in a variety of applications. Our high-quality and durable plastic housings are molded from flame-retardant ABS or impact-resistant polycarbonate for indoor or outdoor applications that require non-metallic enclosures. Available in an array of sizes, shapes and colors, our selection ensures you can find the right solution for any application.

From small plastic boxes for potting applications to heavy-duty plastic boxes for industrial use, we have a non-metallic enclosure solution to fit your needs. Check out our guide on ABS vs. polycarbonate enclosures, or read below to learn more about the basics of Polycase’s plastic enclosures.

What Are the Applications of Plastic Enclosures?

Applications and uses for plastic electronics enclosures are endless, which is why Polycase’s plastic enclosure solutions are the go-to option for professionals in a huge variety of fields. Some popular non-metallic enclosure applications include desktop and handheld devices, remote sensors, junction boxes, industrial control boxes, wireless and telecommunication devices, and more.

The durability and versatility of plastic enclosure boxes enable them to fulfill all of these roles and more. Many of our polycarbonate models feature weatherproof and watertight construction with NEMA and IP ratings. What’s more, both our polycarbonate and ABS plastic enclosures often have flame-retardant properties to help keep your most important equipment safe. Plus, we offer a variety of form factors, including handheld enclosures with useful built-in features like battery compartments and buttons.
