In manufacturing, cookies can be associated with the term cookie cutter, which refers to standardized parts produced to fit specific needs. When it comes to tin can manufacturing, the term can also relate to the small, standardized metal sheets or discs used to form the two ends of a tin can. These cookies are punched out from larger sheets of metal, ensuring uniformity and precision in production. This precision is crucial, as discrepancies in size can lead to difficulties in sealing cans, potentially compromising their integrity.
