[0002] Automotive headlight fixtures include automotive headlight manufacturing molds. When testing the wear resistance and compressive strength of these molds, separate tests are required using wear resistance testing equipment and compressive strength testing equipment. For the first wear resistance test, the fixture must be clamped using the fixture of the wear resistance testing equipment before the test is performed. Then, the fixture is removed and placed on the compressive strength testing equipment, where it is clamped again before the compressive strength test is conducted. Therefore, testing the wear resistance and compressive strength of the fixture requires transferring the fixture and performing two clamping operations, resulting in low efficiency.
