Wire drawing is a process in which wire rods/wires are reduced in diameter by drawing them through cone-shaped openings of a smaller cross section, so called dies. The input usually is wire rod of diameters raging from 5.5 to 16 mm obtained from hot rolling mills in form of coils. The final diameter size of dry drawn wire is between one and two millimetres, wet drawn wire has an even smaller diameter.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
