Comparison of the Mechanical Properties of Rotary Embossing and Restoration Processes

Heat shields are vehicle components that prevent the transfer of the heat that builds up in vehicle components at high temperatures to neighboring elements and the vehicle body. Embossing is a sheet-metal-forming process for producing bulged designs by means of matched male and female rigid roller dies. After the embossing process, embossed sheets are formed in molds shaped like the vehicle component to be protected from overheating. In this forming process, some bulged designs are compressed. In this article, to research this compression process, the embossed sheets are compressed with upper and lower rigid platens, and this process is known as the restoration process. The purpose of this study is to compare the effects of embossing and restoration processes on the yield strengths, tensile strengths, and bending strengths of the sheets.
