Family Injection Molding

Family Molding is an injection mold that contains various shaped cavities to mold all the plastics pieces for one particular part.  Family molding can be used only when the different plastic parts are made from the same material. 


The difficulty with family molding is the natural imbalance of mold flow.  At Crescent Industries to help correct this problem, we utilize mold fill simulation software to learn how the parts will fill in the mold before the mold is even built, giving us the edge to correct potential problems in the design phase.  At the injection molding level, Crescent utilizes sequential valve gating to improve performance, reduce variation and improve balance in family molds.
