In recent years, the development of 5G communication technology and the Internet has progressed by leaps and bounds. The combination of the Internet and traditional industries has given birth to a new form of economic and social development - “Internet +”, which has accelerated the internetization of the entire industry. The integration of Internet thinking into the development of traditional metal craft cultural and creative products has become the key to people’s research. This paper aims to study the design method of cultural and creative products based on the fusion of 5G technology and traditional metal craftsmanship. This paper proposes the basic theoretical concepts of 5G technology and cultural and creative products. The experimental results of this paper show that the current traditional metal craft form score is between 3.9 and 5.2. The category score ranges from 4.8 to 6.1, and the creative score ranges from 3.8 to 5.3. It can be seen that the traditional metal craft not only faces the problem of a single form, but also faces the problem of lack of innovative thinking. Therefore, traditional cultural and creative products have not kept pace with the times. The research on cultural and creative product design that integrates 5G technology and traditional metal craftsmanship is very important.
