ABSTRACT:
A filler material and a heated, catalyzed synthetic resin are sequentially introduced into a mixer. The mixer has a conveying section and a mixing section. The resin and filler are introduced into the conveying section, which forces the combined resin and filler material into and through the mixing section. The mixing section kneads and shears the material to uniformly disperse the resin throughout the filler. The resin/filler mixture is then dispensed into a mold for curing.
