Pre-manufactured Components

Pre-manufactured parts are components of a product that have been manufactured by another factory elsewhere. They are manufactured to a specification, examples are hinges and electronic components.

Designers use pre-manufactured parts because:

      It saves time and effort because not every single item of a product need to be designed
  
      Mass produced pre-manufactured parts are likely to be cheaper to buy-in than to manufacture yourself

      Many pre-manufactured parts are made to a standard so can be selected for a particular purpose

      If a product needs to be repaired, replacement parts are much easier to come by if they are standard pre-manufactured parts

      A factory does not need to invest in specialist equipment to make pre-manufactured parts
