ABSTRACT:
A sealed system process for the elimination (destruction or removal) of superfluous projections, such as unwanted burrs and sharp edges, on shaped or fabricated articles of manufacture, particularly those produced by mechanical shaping or fabricating, by treatment with transient elevated gaseous temperatures in a sealed and confined space. The transient elevated gaseous temperatures in the sealed and confined space are produced, for instance, by the ignition or other suitable reaction initiation of various compositions which are exothermic in the sealed and confined space, by the rapid and substantially adiabatic compression of a gas in the sealed and confined space or by some other manner such as by the rapid movement of a heated gas wave under pressure through the sealed and confined space, such as exists in a shock wave, so that the transient elevated gaseous temperatures are produced. The transient elevated gaseous temperatures that eliminate the superfluous projections usually have a duration of less than one second and the process is essentially self-limiting and selective in the removal of the superfluous projections. Various means of aiding the elimination of the superfluous projections are also described.
