A method of making the basic material and the facial skin of synthetic leather with one round of process includes two units of material injecting devices for respectively making a PU plastic foam layer and a face-skin layer at the same time. The PU plastic foam layer and the face-skin layer are tightly combined together when they are in a condition of half reaction and not fully becoming hardened to finish making the synthetic leather with one round of process, achieving effects of shortening a producing process, saving equipment, labor and electricity, lowering producing cost, and preventing air and water pollution.
