For over 80 years, Seiler has provided world-class solutions in full-service contract manufacturing to partners across industries. Excellence is our guiding principle, and we promise an unparalleled level of quality in every project down to the last detail. As a family-owned and operated business, we also believe that strong relationships are just as important as the quality products and services we provide. While we specialize in high precision machining and optical instrument assembly, our commitment to growth has led to the establishment of five other divisions: Geospatial, GeoDrones, Medical, Planetarium and Design Solutions.
