Abstract

A method of manufacturing a silicone ring consisting of two outer-band halves formed by compression silicone-molding in a first mold and an inner-band formed by placing half of the outer-bands of the ring in a second mold, placing a spacer-insert mold over the second mold, inserting a silicone rubber in the cavities of a spacer-insert mold, inserting the remaining outer-band halves into a fourth mold, inserting the three molds into a compression chamber to vulcanize the outer-band halves and the inner-band together, wherein the first and second outer-bands form a complete ring, and a symmetrical inner-band is formed in between the first and second outer-band halves.

Dependent claims

A method of manufacturing a silicone ring via compression molding comprising:

forming a first outer-band half of a silicone ring and a second outer-band half of a silicone ring with a first compression mold containing a base plate and a top plate press;
placing the first outer-band half of the silicone ring in a second compression mold;
placing a spacer-insert mold over the second compression mold;
placing a silicone rubber through a cavity in the spacer-insert mold and onto a cavity platform on the second mold;
placing the second outer-band half of the rings in a third mold;
placing the third mold over the spacer-insert mold;
inserting the second mold, the spacer-insert mold, and the fourth mold into a compression chamber, wherein the silicone rubber is compression molded and vulcanized to form an inner-band, and the first and second outer-band halves form a complete silicone ring, and a symmetrical inner-band is formed in between the first and second outer-band halves.
