ABSTRACT:
A heat shield is made by stacking a wrapper member made from sheet metal, a flexible ceramic fiber insulation member, and an outer member made from sheet material, and then bending over flanges which extend from the wrapper member. The stacked elements are then bent into the desired shape. To make a heat shield for spark plugs, a support member is also included in the stack and provides mounting legs for mounting the heat shield. To make a heat shield for a transmission unit, mounting hardware is connected to the stack with rivets.
