Company Profile

Manufacturing Excellence Since 1962


We have been manufacturing tooling for many industries since Guill’s founding in 1962. What began as a provider of parts for the US Navy quickly expanded into an extrusion tooling provider for companies throughout the country and eventually throughout the world. 


Our roots as a defense supplier are what makes our manufacturing capabilities exceptional. The requirements that our facility adheres to in order to provide the highest quality products to the US government are the same requirements that are used in our extrusion tooling division, allowing us to be capable of holding some of the tightest tolerances in the industry.
