A study is carried out on the feasibility of using warm forming at temperatures from 100 to 250°C in order to improve the makeability of aluminium sheet components. Drawing tests are performed on 1050, 5754 and 6016 series aluminium sheets. Both box shaped and conical rectangular products are made with a tool with heated die and blankholder. The effect of the temperature on the process limits is investigated.
