When there is a huge factory "X" filling some extraordinary orders, there sometimes comes to a situation when a bigger company need to outsource some work to another. This is called contract manufacturing and it is a very common solution for some complicated (but not only for those) projects. In contract manufacturing one company commissions some work to another company, but still the product is marked by the company which contracts out the job. That means some other factory "Y" fulfils a part of the contract commissioned originally to our huge factory "X", getting paid for the work done. Everybody"s satisfied and the job is well done.
