A heat dissipation component manufacturing method is disclosed. The heat dissipation component has a main body. The main body has a first metal plate body and a second metal plate body. The first and second metal plate bodies together define a chamber. A capillary structure layer is disposed in the chamber and a working fluid is filled in the chamber. An outer periphery of the chamber of the main body has a flange section. The flange section has a sintered welding section. The sintered welding section is perpendicularly connected with the first and second metal plate bodies. The heat dissipation component manufacturing method employs fillet welding to directly perpendicularly weld and connect the first and second metal plate bodies so as to enhance the connection and sealing of the welded first and second metal plate bodies.

A hot-forming die has a heatable lower die and a heatable upper die. The lower die and the upper die have spacer elements to permit flexing. A plate stack including two plate elements is inside the hot-forming die. The plate stack is on the spacer elements in the lower die. The lower die and the upper die are displaced relative to each other when the hot-forming die is closed. The spacer elements of the upper die come into contact with the plate stack. As the closing movement continues, the spacer elements, are displaced into the lower die and the upper die, respectively, and the plate stack is clamped between the lower die and the upper die. The plate stack is then heated by the lower die and the upper die and an internal pressure is applied to an intermediate space between the plate elements by feeding in an active medium.
