Six major problems in the design and manufacture of precision stamping molds

1. In terms of mold design and manufacturing technology, the precision stamping mold design and manufacturing technology innovation is not enough. The key design connotation and technology in many advanced molds and the basic technology, theory and core technology such as 'KNOW HOW' in the manufacturing process are not mastered enough, leading to the overall level of the mold It is difficult to upgrade, and it is always in the technical follow-up and tracking stage, reaching or even surpassing the international advanced level, but lacks the support of relevant design and manufacturing basic technology. 2. In terms of die life, due to the impact of die materials, heat treatment technology, manufacturing and assembly technology and other related factors, the life of stamping dies in China is generally lower than the international advanced level, with a gap of more than 30%. In particular, the low life of one-time sharpening leads to an increase in the number of mold maintenance, which reduces the production efficiency of precision metal stamping parts, increases the cost of mold maintenance, and affects the market competitiveness of Chinese molds. 3. Mold trial technology and mold reliability. Trial mold is a comprehensive experiment, evaluation and adjustment process for molds after the design and manufacture of precision stamping molds. It is a process of concentrated exposure of mold design and manufacturing problems. It is also a stamping mold design, Comprehensive reflection of manufacturing technology and professionals. The reliability and stability of the mold are the evaluation criteria for the quality of mold design and manufacturing and the guarantee for the normal use of the mold. As China lacks in-depth exploration of the design of multi-station and multi-function stamping dies, the invisible knowledge and technology accumulation in the manufacturing process, compared with the international advanced mold companies, the trial of multi-station and multi-function stamping dies, The adjustment and maintenance time of the mold is increased by more than 30%. Compared with foreign countries that are currently studying the cutting-edge technology of molds without test procedures, the gap between China's mold test technology and the reliability and stability of the mold is obvious. 4. In terms of basic theory and key technology of molds, a precision stamping mold design and manufacturer is a very practical expertise. For a long time, China has attached great importance to the practicality of mold design and manufacturing, but due to the basic theory and technology of stamping dies Insufficient attention to research has led to the slow development of basic theories and technologies for mold design and manufacturing. In addition, the specialization of stamping die companies is not detailed enough, small but complete, large and complete mold companies still dominate, the core competitiveness of the company is difficult to form, and the company's own technology and innovation capabilities lag behind foreign advanced mold companies . In addition, the backward technology of mold materials, standard parts and other molds directly affects the overall technical level of China's multi-station and multi-functional stamping dies. Therefore, there are still many weak links in the basic technical support of multi-station and multi-functional stamping dies. 5. New mold technology and its expansion. With the continuous emergence of new processes and new products, foreign stamping dies have moved from conventional single-pair progressive dies to multi-functional combined molds, production line supporting combined mold tooling, extra-large progressive dies and micro The development of parts stamping and forming dies, while most Chinese companies still focus on the serialization and industrialization of conventional single-pair progressive dies, and have not yet mastered special high-precision dies such as super large, high-precision, ultra-high-speed stamping, The key technology of forming stamping dies for ultra-thin, super-strength and micro-parts is not much designed for multi-functional composite dies. Therefore, China also needs to continue to carry out research on the key technologies of new molds, expand its application areas, and lay a solid foundation for catching up with and surpassing the international advanced level. 6. In terms of basic parts and supporting parts, the basic parts and supporting parts of multi-station and multi-functional stamping dies are the basic conditions for the rapid development of the overall mold. However, due to heat treatment, materials, standard parts and other basic mold parts and supporting technologies in China And the quality level is low, the basic parts and accessories of high-end molds mainly rely on imports. Therefore, China urgently needs to improve the technology and quality level of basic mold components and supporting parts. More related information: product/
