Ever wonder why some replacement auto parts work great and last a long time, while others fail or wear out prematurely? The materials used are often the difference. During development of URO Parts and Autotecnica components at our on-site laboratory in Southern California, APA engineers utilize Thermo Scientific X-Ray Fluorescence equipment for the identification of metal alloys, Fourier Transform Infrared Spectroscopy apparatus for polymer identification, and various Shimadzu Universal Testing Machines to test the tensile strength and compressive strength of materials. Use of this modern technology helps ensure conformity with Genuine OE parts, and assures function and design integrity. The result? High-quality replacement parts that work properly right out of the box - and last for years to come.
