The method for manufacturing a metal material with an intermediate hollow and two solid end portions includes a step for preparing a first mold for manufacturing a roughly-shaped metal material with a first inner solid end hollow and a lengthwise intermediate hollow of a preset length. A conical portion is formed around am outer end hole of the mold. The outer conical end of the metal material is pressed in the intermediate hollow to form a second outer end portion of the metal material. Thus, a finished product of metal material with two solid end portions and an intermediate hollow is manufactured. Such a method can surely simplify the processes of manufacture, lowing the cost of production, and strengthening the integrated structure of products.
