Many of our competitors use internal ribbing within their enclosures to create extra rigidity and strength. While this design choice sounds logical, adding internal ribbing poses many complications, which can hinder design flexibility and take up too much space within the enclosure. For this reason, none of our standard molds have provisions for internal ribbing. Exceptionally high-strength requirements for high-impact applications can nearly always be satisfied by our range of design features, wall thickness options and plastic materials, which include ABS, NORYL, Nylon and Polycarbonate. Here at Polycase we’ve come up with design solutions that offer the strength of internal ribbing without the added bulk.
