Our culture is as unique as the solutions we provide and our highly-skilled and experienced team possesses an unwavering desire to push the boundaries of what can be done. None of us believes in saying no. We’re not afraid to invest in new technology if that’s what it takes to deliver the solution – or multiple solutions – you need. We’ve met every challenge that’s come before us head on, and because of it, we’ve developed some of the most innovative products in the industry – products no one else in the world can make. But we don’t stop at simply producing these products. We back everything we do with all the customer support you need, whenever you need it.

Our History

A career of owning and operating a large successful spring manufacturing company gave founder, Dick Witham, the ability to identify a need in unique markets that had difficult applications. Thus, in 1992, Motion Dynamics Corporation was established. Its mission was to help customers solve problems by designing and producing products that require and incorporate the finest wire components and services available. Today, Motion Dynamics Corporation is run by Dick’s son, Chris, and the company continues to enjoy relationships with customers worldwide by providing unequaled quality, innovative processes and technology, and exceptional service.

Our scope and experience allows us to handle the smallest, most complex designs the medical device industry has to offer, and our dedication to our customers’ success as well as our employees’ happiness has positioned us as an industry leader.

We are the future of manufacturing…and we can’t wait to see what the future holds.

Our Space


I tried so many spring suppliers that crashed and burned. I can’t tell you how good these guys are. Their quality is 98 to 100 percent. The other suppliers were 50 to 60 percent. They’re the perfect supplier. They’re so good, we decided to let them do the testing on their parts and to trust their results. We take their data and accept it, and we never do that. These parts have very tight tolerances. They go into jet engines, there are military applications, they go into oil and gas operations thousands of feet below sea level. Failures can be catastrophic.

We come up with these crazy spring ideas and we send them a prototype and they say ‘No problem.’ We might ask them to do it in two weeks, and they’ll ship it to us in a week and we get it to our customers. Other suppliers, it might be four weeks. This stuff is so difficult to make, they’ve been a godsend for us.

For the record you and the team are really impressive with your attention to detail and communication regarding these builds. In my opinion one of our top suppliers in this regard.
