But size effects like changed tribology [3] and material properties [4] usually result in smaller process windows for micro forming operations [5].
For deep drawing the size effect on the properties of material [4] as well as the size effect on tribology [7] are the most important ones [8].
The investigated material was pure aluminum foil with a thickness of 20 µm and a drawing ratio of 1.7.

These experiments were constructed according to the research results, which were awarded with “National Prize for Progress in Science and Technology” or “The Prize of Ministry of Metallurgical Industry for Progress in Science and Technology Progress”.
Furthermore, students can use suitable software to effectively simulate and analyze the gas-solid reactions, distribution of gas flow, resistance of material bed, heat transmission, steel-making and continuous casting in the experimental teaching process.
