ABSTRACT:
A process for producing a breast prosthesis with a concave recess facing the human body. A synthetic resin composition curable to a gelatinous state is enclosed between two thermoplastic films and is shaped in a heated mold defined by a male die and female die. A first film which will face away from the human body is stretched over the female die and heated to permanently conform it to the contour of the die by deep drawing. The deep-drawn film is removed from the female die and an insert having a volume and a free area which correspond to the volume and free area of the concave recess facing the body is then positioned in the female die. The deep-drawn film is placed over the insert in the die and the die is filled with the synthetic resin composition up to its edge. The synthetic resin composition is covered with a second film (cover film) which is welded to the first film over these entire overlapping edges. The insert is removed, the second film is permanently shaped to the contour of the male die which corresponds to the shape of the concave recess and the synthetic resin composition is then cured with the help of a male die.
