introduction：Mold is the main process equipment of industrial production。The development of modern industrial products and the improvement of technical level，To a large extent depends on the development level of the mold industry。Since World War II，The improvement of the degree of automation makes the rapid development of foreign molds。Although China is a large country of mold production,But it is not a mold manufacturing power。To match the spring to the mold，This detail is also the key to quality。Affect the performance of the whole mold。 I am engaged in surface treatment engineering specialty，The surface treatment of die spring, that is, rectangular spring, is investigated。Find the following problem，Bring up for discussion。
