Setting Ideas Into Motion
Since 1950, design engineers have depended on SDP/SI for high-quality components, subassemblies, and engineering expertise. As a company founded and managed by engineers we understand and respond to the developing needs of our customers better than anyone.

When a standard product won't meet your requirements we can provide alternative solutions through custom design and manufacturing. Our engineering and manufacturing teams will partner with you throughout the entire process. By providing design, development, manufacturing, assembly, and testing in one location, we can ensure the end product will meet your expectations.
