Based right outside the City of Philadelphia, GMA has been offering quality products and providing superior service for the manufacturing industry for over 40 years.

​

Since the beginning, GMA has been focused on tool and die production and repair and machine parts.

​

Founded in July of 1972 by Gerald Adasavage Sr. and Martin Adasavage, GMA's first location was in Levittown PA. 

 

After much success and a few years, GMA placed a larger building in its sights. So, in the fall of 1981, GMA packed up and moved to their new location in Huntingdon Valley, PA.

​

In 1990 GMA purchased their first CNC machine

​

In 1991, GMA added a few punch press' to their equipment list. GMA was now not only creating, and repairing dies, but running them as well!

​

In that same year of 1991, GMA also acquired a relationship with one of their biggest customers, Mack Trucks.

​

In 1996 GMA expanded on their already larger shop. The addition was built to house their brand new 400 Ton minster press purchased that same year.

​

From the 1990's to today GMA has been involved and is currently involved in many industries such as Automotive, Trucking, Home appliance and Aerospace industries just to name a few.

​

GMA Continues to look and strive toward the future of the manufacturing industry!
