In recent years, the upsurge of smart manufacturing has swept across China, and major economies around the world are vigorously promoting the revival of the manufacturing industry, and many outstanding manufacturing companies have carried out smart factory construction practices. Industry 4.0, Industrial Internet, Internet of Things, cloud computing and other crazes have become the most important measures to promote the "Made in China 2025" national strategy, including the transformation of enterprises in the injection molding industry.
