Abstract : Except for paper cutting machines, the printing machinery manufacturing industry has basically completed the strategic transition of using frequency converters for speed regulation. With the rapid growth in demand for printing equipment and the upgrading and transformation of outdated equipment, the demand for frequency converters will further increase. Domestic frequency converter manufacturers should further understand the characteristics of frequency converter application in printing equipment and promote the localization of frequency converter application. Keywords : Printing machine, frequency converter, market 1 Introduction During the "15th Five-Year Plan" period, the printing machinery manufacturing industry achieved rapid development, making remarkable achievements in both meeting the needs of the printing and packaging market and in export earnings. The main driving force behind the rapid development of the printing machinery manufacturing industry, besides the overall economic development environment in my country, comes primarily from the rapid development of the printing and packaging industry. This includes both natural market growth and government policy incentives. To accelerate technological progress, the government has introduced a "Catalogue of Outdated Production Capacities, Processes, and Equipment," guiding the further development of the printing machinery manufacturing industry from the perspective of equipment technology transformation. Imports of printing machinery equipment still account for half of the domestic market. There is huge growth potential for digital equipment and high-end printing equipment, and expanding exports and reducing imports remains the main direction for the development of the printing machinery manufacturing industry. The fundamental driving force for the development of the printing machinery manufacturing industry comes from independent innovation. The widespread application of frequency converters and servo technology will be the main technological development direction for the printing machinery manufacturing industry.
