Die-casting and mold are both different and related. The birth of the die-casting mold industry is the perfect combination of the two. In other words, die-casting, mold and die-casting mold are three different industries, and their relationship mainly exists in several ways. : Die-casting and mold integration, molds are all manufactured by themselves, and few molds are made for other companies; professional die-casting mold manufacturing, no die-casting; only die-casting, no mold-making ability. With the intensification of industrial division of labor, the gradual blurring of industry boundaries and the development of cross-industry, the three industries should strengthen ties, learn from each other, merge the three industries into one, and exist in the form of "integration". The die casting mold industry will usher in more and greater development opportunities and space.
