Abstract
According to current development trends for automotive parts lightweight is a key issue in improving fuel efficiency and CO2 reduction Compared to steel and aluminum magnesium has a relatively low specific gravity However it is challenging to use magnesium to produce a product at room temperature because magnesium has a hexagonal closepacked crystal structure Therefore the structure is not suitable for plastic deformation without using a heating system As a result a magnesium alloy sheet and die need to be heated from 250 to 300ÂșC This paper presents the development of warm forming technology for automotive dash panel using magnesium alloy sheet
