  • System, method and apparatus for polymer seals to form positive shut-off for insert molding of liquid silicone rubber
    Patent number: 9085102
    Abstract: An object is formed on a component with a positive flash shut-off during insert molding operations. The mold has a base with a cavity and a port that delivers a liquid to the cavity. The base has a component support structure for supporting the component and pockets formed on opposite sides of the cavity. The pockets are slightly spaced apart from the cavity by thin partitions. Inserts located in the pockets and are formed from a polymer. Both the partitions and inserts comprise the component support structure. The inserts have a dimension that is smaller than that of the base and partitions so as to form a compression fit around the component to reduce or eliminate flash down the component during the molding process.
