In the world of sheet metal contract manufacturing, designers and small and medium enterprises, startups, and even well-known publicly traded companies, come to an agreement with specialized companies in metal processing or outsourcing firms, otherwise known as trading companies, to delegate sheet metal manufacturing orders. These projects consist of the following stages: design, production, assembly and packaging. This contract is an example of the shared manufacturing system, where fabricating shops or outsourcing companies perform tasks such as design drafting, laser cutting, bending, welding, riveting, and assembly in line with equitable conditions. As a third step, the fabricated sheet metal parts are supplied to the contracting authority according to the specified dimensions, thus ensuring both quality and timelines. Along this journey, the expenditure on raw materials, equipment, labor and packaging is reduced, since all are taken care of by the business factories specialized in sheetmetal, thus, costing less. Therefore, the contracting party will be able to allocate its effort in sales, marketing, and customer service activities. This collaborative model simplifies the process of getting sheet metal products to market as soon and economically as possible, an aspect that surely benefits the contracting entity.
