<p>PURPOSE:To reduce the manhour for work and reduce weight by enclosing the caliper body made of steel plate or steel iron with aluminium alloy in the part of a hydraulic cylinder and casting the combined caliper body. CONSTITUTION:A caliper body 1 casted from ductile is set in an aluminium casting mold, and aluminium or aluminium alloy is poured, and forming the part 2 of a hydraulic cylinder, and the caliper body 1 is enclosed and casted. Thus, the caliper integrally casted from ductile and aluminium can be obtained.</p> |
