High-performance, single- and multiple-cavity molds for a wide variety of materials


Unlike compression molding, transfer molding does not place uncured rubber directly into the mold. Instead, it is kept in a transfer pot, which is positioned above the cavity area. When ready, the mold is transferred into the cavity by a piston through a runner, sprue and gate system. By utilizing heat and pressure, the rubber becomes vulcanized or cured. Many rubber product manufacturers consider custom rubber transfer molding more accurate than compression molding. Its accuracy reduces reject rates on small to medium runs of precision custom rubber parts or components. Additional advantages include shorter cure times and reduced mold making labor.
