Bob Hobbs, founded SDM in 1994 with the goal of changing the way mold fabrication and injection molding services are provided. Bob made the decision to establish quality systems as the heart of the structure of the company and immediately becoming ISO certified and FDA registered. Scientific molding processes were implemented from the start of SDM.

He earned a B.S. degree in Mechanical Engineering from Cal State Fullerton in 1984. He gained valuable experience working for companies both large and small, original equipment manufacturers as well as custom molders. Beckman Instruments, Rain Bird, Cimco, and C. Brewer are some of the well recognized employers that utilized his skills.

Bob's name is listed on many product designs that are now patented. He is regularly involved in the design of new plastic products components and assemblies, from medical to irrigation to consumer products.

Innovative tooling design, and a willingness to try new concepts and stretch the proper application of plastics to advance the quality of life is a major focus for Bob.
