Enkei - EN-441-780-2645BK

Enkei has adopted Durville die casting and MAT process to ensure cast aluminum wheels have strength comparable to forged ones. The Durville process involves pouring molten aluminum alloy into the mold from the inner rim side, with the disc side facing downward, rapidly quenching and solidifying from the disc side, creating a finer metallic structure that enhances tensile strength, yield strength, and elongation. The MAT process spins and rolls the wheel rim on a mandrel, creating a "metal flow" in the aluminum alloy's metal structure, similar to forging. This hybrid process offers high material strength at a more affordable cost than forged wheels, and allows for greater design freedom on the wheel face. Enkei's design capability, backed by vast wheel design data and computer-aided engineering 3D simulation, ensures high stiffness without adding weight by optimizing spoke layout, cross-sectional shape, and rim profile, as well as identifying and shaving down areas with minimal stress concentration.
