发明名称 Silicone foam symmetrical inversion molding process
摘要 A method for molding silicone foam into an article having the features of a designated object. The method includes the steps of introducing a silicone foam mixture into a first mold having a first cavity, wherein the silicone foam mixture forms a first molded object that has a shape which is representative of the first cavity; removing the first molded object from the first mold; pressing the first molded object into a second mold that has a second cavity, which has a basic profile that is representative of the article, the first molded object forming a layer of foam on the top edge of the second mold; cutting the layer to form an opened celled surface on the top surface of the first molded object; and releasing and removing the first molded object from the second cavity. The opened celled surface acquires the configuration that is representative of the second cavity, while the first bottom surface returns to the shape of the first cavity. A detailed layer having the specific attributes of the article can be applied to the first molded object through the use of a third mold.
