Guill Tool & Engineering Co. has found a way to overcome the limitations of manufacturing advanced tubular products. The West Warwick, R.I.-based firm has developed a technology it calls NanoFlow that can create more than 1,000 layers from a single extruder (the average number of layers produced from a single extruder is about 12). The NanoFlow layer thickness ranges from a micrometer (1 millionth of a meter) to a nanometer (1billionth of a meter). The company claims its NanFlow technology uses less material as well as fewer different kinds of materials, and produces an environmentally friendlier product. The firm claims itsNanoFlow technology improves the performance properties of extruded products in various applications, according to the company. The new technique can help increase impact and fracture toughness, for example, as well as fortify tear strength. It also can be used to limit crack propagation (by combining strong, brittle materials with soft ductile layers) and enhance the engineering of barrier properties by designing thin layers that force materials to crystallize. The company claims gas barrier-type properties also are possible.
