Introduction to portable enclosures

There has been a rise in the demand for portable enclosures because of the continuing shrinking of electronic components, including cell phones, Personal digital assistants, fax machines, instrumentation tools, and remote controls. A wide variety of portable enclosures are available to suit your needs in terms of design, material, colors, finish, and size.


MATERIAL Of Portable Enclosures

Plastic and metal are the two most popular choices for portable enclosures. In most cases, cost-effectiveness dictates the usage of ABS or polycarbonate plastic. Applications that necessitate additional robustness, rigidity, and EMI/RFI shielding often utilize die-cast aluminum.



CONSTRUCTION Of Portable Enclosures

There are primarily two types of construction used for portable enclosures.

  • Traditional Design
  • Clamshell Design

In the traditional design, two-piece designs have a top and bottom shell. Clamshell styles are comprised of four different pieces: the top and bottom shells and the front and back panels. The top and bottom shells are screwed together and capture the front and back panels. Integrated component guidelines and PCB mounting hooks could be molded into a top or bottom shells.

The traditional design is more cost-effective and accessible to gasket than the alternative. The clamshell style allows for easier component access and placement. The front panels of clamshell designs can be manufactured from a different material, color, or transparency, but they are more challenging to seal in an environmentally safe manner. Rectangular, T-shaped, spherical, and cylindrical portable enclosures are all readily available. The precise shape is determined by the particular application being used.




Gaskets enable environmental sealing in several portable enclosure designs to meet NEMA and IP rating requirements. EPDM, neoprene, and polyurethane are the most common materials used to make gaskets; however other materials may be suitable for specific tasks.

Extruded gaskets are the most cost-effective option for low-volume uses. They are shaped using a cutter and fitted into the mouldable grooves on the corresponding enclosure edges. A variety of manufacturers are now using form-in-place gaskets. While two-component polyurethane resin is typically used for form-in-place gaskets, a one-piece molded unit customized to the box’s dimensions may be the most cost-effective option when working with larger volumes. Die-cast aluminum enclosures are the most effective form of electromagnetic interference (EMI) shielding.

However, plastic enclosures covered with conductive paint might be used for less demanding applications. Depending on the required level of conductivity, the paint may have powdered nickel, copper, or silver in its composition. Nickel is the most prevalent, inexpensive, and least conductive metal, while silver is the rarest, most costly, and conductive metal.

The gasket material must also be conducive to EMI/RFI applications. Gaskets loaded with carbon or silver particles are available from various manufacturers. Metallic enclosures can also make use of gaskets with a wire-mesh outer jacket.



There is a wide selection of portable enclosures available from different manufacturers; some have insert-molded regions on the outside face for labels and graphics, display cutouts, and circuit board guidelines
Some manufacturers offer additional CNC machining services, such as adding custom perforations, cuts, silk screening, pad embossing, and EMI/RFI shielding.
Black, gray, and off-white are the most popular hues in business. It’s possible that there would be minimum orders and a longer turnaround time for specifically chosen colors.
Plastic portable enclosures typically feature exteriors with fine textured finishes that prevent and conceal scratches and other minor flaws. Surfaces within are generally smooth. The smooth surface finishes typical of die-cast aluminum enclosures are amenable to additional treatment with chemical conversion coatings. These processes are typically used to improve paint or powder coating adherence and corrosion resistance.
