Key Points of Quality Control


Materials testing: raw materials, chemical composition, blank metallographic / streamline / organization, strength, performance, etc..Spline
Key dimensions: key dimensions and important features are controlled by special inspection tools, special equipment and 100% inspection.Crack test for cage
Performance test: static torsion test, fatigue test, high and low temperature test, aging test, function test and dynamic life test.Performance test
Heat treatment: heat treatment of the depth of the layer, hardness, metallographic structure, strength for each batch or each furnace for sampling inspection.
