SDP/SI was founded by engineers with one idea in mind: “Customer satisfaction is our goal”. This entails far more than just selling people the products they need. We pride ourselves on having some of the most knowledgeable engineering staff around. These engineers are ready to aid you in any way possible. If you need to know anything about one of our thousands of standard items, don’t hesitate to call. If you need a custom part made, we’ll not only make it for you, but create an open dialogue with you to ensure you get exactly what you need at the best possible price. We also publish a large amount of technical documentation on the function, application, and advantages of our many product lines to help you make your own informed decision.

Any engineer knows that a great mind is limited by the tools at its disposal. That is why SDP/SI spares no expense when it comes to maintaining a technologically advanced manufacturing facility. We have everything from injection molding machines to sophisticated multi-axis CNC milling machines, which allows us to fabricate high volumes of all kinds of plastic and metal components. We can also create complex assemblies, particularly precision gear assemblies. Our manufacturing staff is just as knowledgeable as our engineering staff, which assures that the parts we make always adhere to the high quality standards our customers have come to expect.

Most important of all, engineers are never satisfied with something just because it works fine. Whether it’s a more efficient way to manufacture a part, a design improvement to boost performance, or a way to expand into new markets, SDP/SI is always looking to innovate. Contact us today, and let us set your ideas in motion.
