Exhaust Manifold/Turbocharger Heat Shield:
Inner and outer base material layers: aluminum-coated steel sheets (SA1D, SUS304, etc.);
Middle layer: ceramic fiber cotton with temperature resistance of 850–950°C; high-temperature resistant, high-compression high-silica oxygen cotton with temperature resistance up to 1,050°C;
Forming processes: combined edge wrapping, riveting, and other techniques;
Heat insulation efficiency reaches over 85% below 850°C.
