Complete manufacturing, sheet metal is a combination of sheet metal work and assembly. Machining is often included, but the sheet metal work dominate this type of manufacturing.
Complete manufacturing includes sheet metal work as the main process, but extensive assembly is usually required and somtimes also electronics and machining. For example, complete manufacturing is for outsourcing the manufacturing and assembly of electric cabinets, where a housing in sheet metal is made and assembled and electronics are mounted. Then a final product is delivered to the buyer. Most sheet metal workshops are experienced in this kind of manufacturing as they are required to work closely with their customer and make quick changes to the product.
It is unusual that all parts are made in one workshop. Most of the time, the production is to outsourced to some degree. When the parts are purchased, the work shop assembles the final product and delivers it to the customer.
The sheet metal workshops that do complete manufacturing are good at communicating with their customers and to handle large and complicated projects. When a buyer orders complete manufacturing, the buyer expects a perfect product or component, which is delivered just-in-time or to be sold immediately.
