The development of precision stamping die manufacturing technology in China 'hardware'

Precision stamping die planning and production skills innovation is not good, many key planning content and skills in the mold and the skills, theories and core skills in the production process are not good, which makes it difficult to improve the overall level of the mold. It has been in the skill follow-up and pursuit stage. Beyond the world level, it lacks the support of relevant planning and production skills. 2. Die service life Due to the influence of precision stamping die materials, heat treatment, production and installation skills and other related factors, the use time of precision stamping dies in China is basically lower than the world level, with a distance of more than 30%. In particular, the number of mold repairs has led to an increase in the number of maintenance of precision stamping dies, reduced the production rate of precision metal stamping parts, and increased the maintenance cost of precision stamping dies, thereby affecting the market competitiveness of my country's precision stamping dies as a whole. 3. Mold trial and reliability Trial mold is a process of theoretical experiment, comment and inspection of precision stamping die after the design and production of precision stamping die is completed. It is the actual display of mold design and production problems, and it is also the design of precision stamping die. A comprehensive reflection of production skills and the technical level of full-time personnel. The reliability and stability of precision stamping dies are the benchmark for the design and production of precision stamping dies and the guarantee for the normal use of precision stamping dies. Because our country lacks the in-depth exploration of the invisible knowledge and skill accumulation in the design and production process of multi-station and multi-function precision stamping dies, compared with the world's precision stamping die companies, my country’s multi-station and multi-function precision stamping die The adjustment and repair time during mold trial and mold use increased by more than 30%. Compared with foreign countries that are currently studying the cutting-edge technology of precision stamping dies without trial procedures, the distance between the testing skills of precision stamping dies and the reliability and stability of the mold cannot be concealed in China.
