The Process

Jenkins-Martin fiberglass drum shells are produced in a unique composite molding process specifically designed to create a truly one-piece, solid shell. An individual strand of glass fibers, saturated with a specialized resin, is continuously wound around a mandrel (mold) until the desired length and thickness is achieved. The material is then heated for a prescribed period of time at a specific temperature. As the material cures (hardens) the glass and resin bond together to become a single, solid unit. The cured material is then extracted from the mandrel and cut to size. The resulting shell gets sanded smooth and finally, the edges are trued.
