We have developed an expertise in manufacturing highly complex, tight tolerance, system critical components. Our technical capabilities can be utilized in numerous applications including for use in battery electric, hybrid electric, and internal combustion engine vehicles. The group currently manufactures components on a high-volume basis for use in power steering, braking, transmissions, and gasoline fuel system applications, along with components utilized in heating, ventilation and air conditioning and diesel injection and diesel emissions treatment applications. This expertise has been gained through investment in technical capabilities, processes and systems, and allows us to provide skilled program management and product launch capabilities. Power Solutions Power Solutions is focused on growth in the electrical, general industrial, automotive, and medical end markets. Within this group we combine materials science expertise with advanced engineering and production capabilities to design and manufacture a broad range of high-precision metal components, assemblies, and finished devices used in applications ranging from power control to transportation electrification. We manufacture a variety of products including electrical contacts, connectors, contact assemblies, and precision stampings for the electrical end market and high precision products for the aerospace and defense end market utilizing our extensive process technologies. Our medical business includes the production of a variety of tools and instruments for the orthopedics and medical/surgical end markets. Competitive Strengths High-precision manufacturing capabilities We believe our ability to produce high-precision parts at high production volumes is among the best in the market. Our technology platform consists of high precision machining, progressive stamping, laser welding, material science, assembly, and design optimization. In-house tool design and process know-how create trade secrets that enable consistent production tolerances of less than one micron while producing millions of parts per day. Parts are manufactured to application-specific customer design and co-design standards that are developed for a specific use. The high-precision capabilities are part of our zero-defect design process, which seeks to eliminate variability and manufacturing defects throughout the entire product lifecycle. We believe our production capabilities provide a competitive advantage as few other manufacturers are capable of meeting tolerance demands the volume level requested by our customers. As the need for tight-tolerance precision parts, subassemblies, and devices continues to increase, we believe that our production capabilities will place us at the forefront of the industry. We have differentiated ourselves among our competitors by providing customers engineered solutions and a broad reach and breadth of manufacturing capabilities. We believe it is for these reasons, and because of our proven ability to produce high-quality, precision parts and components on a cost-effective basis, that customers choose us to meet their manufacturing needs. Differentiated, system-critical products The tight-tolerance and high-quality nature of our precision products is specifically suited for use in the most demanding applications that require superior reliability. Our products are critical components to the operation and reliability of larger mechanical and electrical systems.…
