Dumore Design

The Dumore legacy of quality begins with a quality design and manufacturing process.

We work to fully understand your application, goals, budget parameters and time frame in order to provide a design and manufacturing program that works right the first time.


Using the latest design and testing equipment our design and engineering team evaluate the application and develop drawings, costing and prototypes. If testing is required, we walk you through the testing process and incorporation of any changes resulting from testing.
