A medical facemask includes an air cushion to form a seal around a patient's mouth and nose. The air cushion has a facing side contacting the patient's face. The facing side of the air cushion is soft and thin. The facing side has a thickness between 0.15-0.2 mm. The mold for manufacturing the medical facemask includes two mold blocks abutting each other and each having a cavity defined to correspond to each other. An inlet is defined and communicates with one end of the cavity where a nose portion of the medical facemask is formed. The two mold blocks each has multiple outlets defined to communicate with the cavity. To form a thinner facing side, the diameter of the outlets of the mold block forming the facing side is two to five time greater than that of the outlets in the other mold block.
