Assembly involves taking all the subcomponents of a part and putting them together to get a final product. After the completion of metal parts there is usually “Some Assembly Required.”
Assembly can be as simple as bolting a few parts together with basic hardware. In other cases it can be necessary to install wiring and other complicated electrical components. For certain applications it is beneficial to kit the parts and package them to be ready for the end user. Whatever the application, assembly takes the basic parts and combines them it to the final desired product.
