While Envision does not provide NEMA or IP certification on our custom plastic enclosures, we can certainly make plastic enclosures and other types of plastic housings with design elements to help with weather resistance, moisture, and dust protection. We typically use a screw down lid concept with either an expandable foam/neoprene gasket or an O-ring gasket. When secured, the cover compresses the gasket on the internal frame to create a tight seal.
