Mould parts production demonstrated by the high-precision, engage in complex, engaging consistency, engaged in manufacturing efficiency and low consumption, and other processing methods could be compared. The level of mold production technology, has become a measure of a country's level of product manufacturing an important criterion, particularly Die processing technology, Die production processes rely on the principal characteristics of die stamping equipment and completion of processing, and ease of automation, high productivity operation Simple. CAD / CAE technology as an important means of technology is more and more widely applied in the mold industry. ﹤br﹥ With constant scientific and technological progress and social development of the high-speed, product upgrades become ever faster. Both industrial products and household electrical appliances, most applications Molding. Therefore, the accuracy of die products on the increasingly high demands, becoming increasingly popular. The mold is a typical technology-intensive products, in order to clearly express design intent, the design must spend a lot of time to map the mold base, push, slide structure relatively fixed parts. At present, CAD / CAE development for the large number of die design provides convenient. Especially in recent years, CAD / CAE technology developed very quickly, and the increasing scope of application, and has made considerable economic benefits.
