China's modified material industry will soon face industrial transformation. The low-end low price and low level competitive material system will gradually lose the market. All enterprises will pursue higher technology level and higher value-added product development. At this time, the three screw will be a kind of main type, and it will be possible in the future. System, high viscosity material mixing, high filling composite system, and high demand for dispersion and mixing will play a good role. The other twin screws are first developed by Germany, Italy and other countries. Most of our manufacturing enterprises are in the imitation stage, without their own independent intellectual property protection. In the future, if the three screw can be applied and popularized, it may become the first set of innovative process routes established by China, so it is possible to create a set of independent intellectual property system from the system of technology, equipment and products, which has an immeasurable role in promoting the development of China's manufacturing industry.
