ABSTRACT:
An apparatus for curing a sheet molding compound which comprises at least one pair of molds disposed along a path of transport of the sheet molding compound. The molds defines a cavity therebetween for passage of the sheet molding compound, which has been generally semi- cured and shaped by a shaping apparatus to a predetermined shape, to heat the generally semi-cured sheet molding compound. At least one of the molds is in the form of a movable mold effective to vary a cross-sectional shape of the cavity to follow a thermal expansion and shrinkage which take place in the sheet molding compound during a curing process.
