Qian Yaoen pointed out that China is the world's largest producer of injection molding machines, with an annual total of nearly 100,000 units, annual sales of nearly 20 billion yuan, of which more than 1 billion US dollars worth of exports. As a computer control system for the "brains" of injection molding machines, there is currently no unified industry technology standard. At present, China's plastics machinery industry is in a new period of development. It is of great significance and heavy tasks to vigorously promote standardization work. Relevant companies should strengthen their awareness of standardization, establish a market-driven, enterprise-centric philosophy, actively participate in the formulation, revision, and implementation of standards, and strive to formulate more Chinese standards for presses that are recognized by the market and are well-known at home and abroad. In order to enhance the international competitiveness of China's press products, China's presses will be promoted in the international standardization field and contribute to the sound and rapid development of the industry.
