Enclosure for Electrical Industry

Enclosure for Electrical Industry

Woodland was contacted by a customer to discuss our metal-to-thermoset conversion experience pertaining to an existing metal enclosure product assembly the customer had. After reviewing part requirements and geometries, Woodland was able to partner with the customer to convert the existing aluminum parts to thermoset, drastically reducing part weight and unit pricing for the customer over the metal assemblies through part consolidation and also increasing product performance with corrosion resistant properties thermosets provide. The part weight of the injection-molded thermoset enclosure was reduced from the prior aluminum design by nearly 2 lbs.!

These thermoset enclosures are injection molded in a 500T thermoset injection molding machine with molded in bracket inserts, and are then tapped and inserted with threaded brass inserts post-mold. A mating lid to the enclosure is also thermoset injection molded before being digitally printed with the customer’s logo and identification.
