Manual assembly is the process of putting together parts or components by hand, rather than using machines or automated systems. This method is often used in industries like electronics, furniture, and toys, where precision and attention to detail are crucial. Workers follow specific instructions to ensure that each item is assembled correctly. In manual assembly, tools such as screwdrivers, pliers, and wrenches may be used to help fit pieces together. This approach allows for flexibility and customization, making it easier to adapt to different designs or changes in production. It also enables workers to identify and fix any issues during the assembly process.
