This marking out may be done by hand or machinery, and then passed on to the next work station where a worker will cut the marked piece and pass it on to the next production stage. This process will be continuous, with workers carrying out the same tasks over and over again to produce a production line. Companies that use this method usually make a single product, such as televisions, cutlery or packaged foods. These products are always in demand and lose value quickly, so they are mass produced. Custom Manufacturing is usually the method of production used when unique products are made, sometimes on individual customer demand, such as designer clothes, jewellery or custom furniture.
Workers are usually very skilled and work on the same product themselves from start to finish.
Custom manufactured goods are usually of high quality and more expensive than mass produced goods. The group is to collect all the necessary equipment and custom manufacture identical products, using hand tools and working drawings. Each pupil in the group will manufacture one product on their own and will be responsible for every process in the manufacture in the making, finishing and assembling of the product. Each pupil must time the manufacturing process. The group is to set up a continuous manufacturing line, with a 'work station' for each manufacturing process.
