coreless engine mount and manufacturing method thereof

Core-less engine mounts (3) of the present invention to form the extending portion which resulted in an integrally in the mounting bracket (10) for fixing to accommodate the mounting bush 30, the region for the mounting bush (30) by vulcanization integrally formed to aluminum (AL) a core made of a material less support bracket 20 is included by being be a natural frequency impact greatly reduced by the weight reduction due to aluminum (AL) material, in particular, the mounting bush (30) is coreless support bracket 20 direct vulcanization whereby the engine mount durability required during a crash while being the deletion process by bolting fastening operation also has a characteristic is satisfied.
