A water-cooled heat dissipation module assembly capable of cooling a power module of a vehicle driving inverter system using a battery or fuel cell. The water-cooled heat dissipation module assembly includes a housing unit provided in the form of a housing having an opening portion at least partially opened at one side thereof. The housing unit and at least a part of a rim region of the cooling unit are made of a plastic material, and the housing unit and the cooling unit are joined to each other by plastic welding using a laser.

The present invention relates to an eco-mold apparatus for manufacturing a piston, a mold apparatus for manufacturing a piston, and a piston manufacturing method, which mold each part of a piston while decreasing the weight of the piston, and the apparatus may comprise: a first eco-mold part which may move forward or backward in a first direction to shape a portion of an eco-part of a piston; a second eco-mold part which may shape-match with the first eco-mold part to mold another portion of the eco-part of the piston; and a piston pickup part which picks up the piston over the second eco-mold part, so that the piston pickup part can separate the piston from the second eco-mold part.
