I. dressing of mold products after vulcanization

During vulcanization of rubber mold products, the rubber material will flow out along the parting surface of the mold, forming an overflow rubber edge, also known as burr or fly edge, how much and thickness of the rubber edge depends on the structure of the mold, precision, plate vulcanizing machine plate parallelism and the amount of glue. Modern products made from rimless molds have very thin adhesive edges that are sometimes removed from the molds or removed with a light rub.
