Abstract

Heat shields are used on most engines to protect components and bodywork from heat damage. With regular driving conditions, heat shields need to protect parts from nearby heat sources with surface temperatures up to 650°C. Aluminum heat shields are able to protect against quite high temperatures. Aluminized steel sheets are required for heat shielding in the highest temperature range. Lightweight materials such as aluminum alloys are used to realize low fuel consumption for automobiles. The influence of embossing for heat shield parts in the press forming of Al alloy sheet after embossing was examined. This paper is to develop heat shield parts using aluminum alloy sheet for automobiles to improve the formability and reduce the wrinkling.
