Many composite parts, once molded, are not net shape and must be machined or cut to meet finished dimensions. Some parts require drilling to accommodate fasteners and other hardware. Machine tools designed to cut composites are used in such applicaitons.
Although cooling towers traditionally have been made with wood and concrete, composite materials are gaining acceptance due to their corrosion and rot resistance, light weight and ease of installation.
