Mold is the basic technological equipment in industrial production

2023-02-17

At present, although China's total annual mold production has ranked the third in the world, with stamping molds accounting for more than 40% of the total mold production, there is still a considerable gap between China and Germany, the United States, Japan and other developed countries in terms of the overall mold design and manufacturing level and standardization. Represented by large panel dies, China has been able to produce some car panel dies. The design and manufacture of car panel dies is difficult, and the quality and precision requirements are high, which represents the level of panel dies. The design and manufacturing methods and means have basically reached the international level, and the structure and function of the mold are also close to the international level. It has made a big step forward in the process of car mold localization. However, compared with foreign countries, there is still a certain gap in manufacturing quality, precision, manufacturing cycle and cost. The multi-station progressive die and multi-function die, which mark the advanced level of stamping die technology, are the precision die varieties that China focuses on developing. Compared with the multi-station progressive die and multi-function die abroad, there is a certain gap in manufacturing accuracy, service life, die structure and function.
