Problem: Increased competition and the rising price of parts Solution: The selection of a sole-source provider of an AS9100 electromechanical assembly. Results: Optimized design and improved system performance of an assembly that met strict ITAR and DoD quality standards and regulatory mandates.
Problem: A client that provides innovative electrified powertrain solutions for commercial transportation urgently required a vibration isolator with lower conductivity and unique specifications that did not exist at the time. Solution: The creation of a new, elastomeric compound and prototype to handle the large current...
