Several enclosure manufacturing companies utilizes the internal ribbing in making their electronic enclosures to make it extra rigidity and to also make it more durable. Design engineer might take this approach as a logical strategy but the addition of internal ribbing might bring some complications on the electronic enclosure. Given its ability to give strength, it can hinder the flexibility of the design and it can take up internal space in the enclosure. Sure, this strategy also gives some cons and disadvantages.
For this very reason, some of the electronic enclosure manufacturers chose to have their standard moles to not allow provisions for any types of internal ribbing. If industrial companies needing electronic enclosure has a need for high-strength requirements for their process applications that posses high-impact use, some of the manufacturers that does not want internal ribbing offers wide range of design features that can satisfy this need. This includes options for wall thickness that plastic materials, ABS NORYL, nylon and polycarbonate materials for enclosure provides. These companies can give the advantage of an internal ribbing without the additional bulk inside the internal enclosure space.
Aside from the bulky feature and possibility of less space, there is also one major disadvantage to internal ribbing. Some of the plastic enclosure are required to have custom holes and cutouts for cable glands. When an internal ribbing is installed inside the enclosure, it might prevent the cable glands to go inside the enclosure and it might obstruct the holes. Milling cutouts or holes on the internal ribbing is complicated to do and it is not cost efficient, to be honest. In addition to this, the internal ribs can greatly reduce the amount of space that is available inside the enclosures and it can limit the space provision of the components that can be placed inside the electronic enclosure.
With this in mind, enclosure manufacturing companies offers some best design alternatives. The design engineers can add exceptional strength to the enclosure by redesigning the overall shape of the structure of the enclosure. Given the careful calculation of the design, given with proper analysis and testing, some of the manufacturers of enclosure can give the same strength an internal ribbing can give inside the enclosure.
For some of the outdoor applications that requires high strength and impact resistance for electronic enclosures, manufacturers can also offer industrial or production companies an increased wall thickness for electronic enclosures. The enclosure boxes that are specifically designed to have this type of strength and impact resistance can have walls up to 25% thicker. Majority of the NEMA rated enclosures are designed with increased wall thickness.
