Large or small, FDS can mold anything. Check out the following galleries for examples of our work. FDS can produce complex matrix molds with fiberglass jackets, rotocast block & case molds, autoclaved pressure casting and five piece block molds. FDS can produce your castings in resin, flexible rubbers, water clear cast, custom tinted, fiberglass, expanding foam and many other products. All of our fiberglass parts are cast with a heavy resin gel coat and depending on the weight, we will run the part in cloth or chop.
