Trega Corporation was founded in 1973 to produce precision aluminum castings utilizing the permanent mold casting process. Initially, we manufactured furniture components for the fast food industry and traffic light bases for the city of Philadelphia. In 1996, the addition of a dedicated CNC machine for post-casting operations allowed Trega to provide customers with fully machined parts. We moved into our state of the art facilities in 1998.
