Since 1950, design engineers have depended on SDP/SI for high-quality mechanical components, assemblies, custom solutions, 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. Over 100,000 inch and metric dimensioned components are available as standard catalog items for fast turnaround.

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.
