Comp Cams uses only the best Super Clean materials in their valve springs because the requirements are more stringent than for any other application in the world. Metallurgist at the steel mill and spring manufacturing plant have devised methods of taking raw materials and turning them into the spring materials that only COMP Cams has access to using. 100% of Comps valve spring wire is eddy current tested to check for surface defects twice. The wire is tested after the drawing process is performed and again just before the spring wire is fed into the spring coiler. Comp valve springs are processed in a dedicated cell utilizing the latest in CNC equipment. This dedicated cell only produces springs made to the exacting tolerances of COMP Cams . Each spring is CNC coiled, stress relieved, ground, shot-peened and heat set by only the best people, dedicated to that work cell and to producing consistent and accurate parts. Metallurgist at the spring plant are constantly performing destructive and non-destructive tests after each process to be sure that every spring made is as good as the last. These tests are performed on sophisticated equipment such as a Servo Hydraulic Cycle Tester, Scanning Electron Microscope and X-Ray Diffraction Residual Stress Machine.
