An improved method for making a breast enhancer comprises placing a first and second film of thermoplastic material adjacent one another and forming a temporary adhesion seal therebetween. The temporary seal is in the form of a band that defines a parameter of a bag formed between the two films. A sufficient volume of liquid silicone composition to form the breast enhancer is introduced into the bag, and the air-bubble free filled bag is placed between a top mold and a bottom mold. The top and bottom molds are compressively engaged to encase the filled bag within a mold cavity formed between the mold surfaces. At least a portion of the sealed band is disposed within the mold cavity, and at least a portion of the band is compressed between a seal surface of the top mold and a rim of the bottom mold. The temporary seal is opened to allow the liquid silicone composition to migrate between the films and fill the mold cavity. The liquid silicone composition is cured and a weld is formed between film portions positioned between the rim and seal surface. The top mold is withdrawn from the bottom mold, the breast enhancer is removed from the bottom mold, excess edges of the films are trimmed off, and the breast enhancer is ready for packaging and shipping. |
