Inspection refers to the process of inspecting and testing metal hardware components produced during the manufacturing process. The inspection process typically includes visual inspection, dimensional inspection, material inspection, functional testing, and other aspects to ensure that the produced metal hardware components meet design requirements and customer specifications. Inspection can be performed manually, using instruments, or through automated methods, offering advantages such as high inspection efficiency, accuracy, and repeatability. The inspection process is crucial in metal hardware component manufacturing as it ensures consistent quality, adherence to standards, and meets customer requirements.
