China's smart manufacturing needs to leapfrog these six constraints in its development

The era of Industry 4.0 is not a change in one aspect of the entire world. It will affect the entire industrial production process and thus affect people's lives. I can't imagine how smart the earth will be in the era of Industry 4.0. In recent years, China's smart manufacturing technology and its industrialization have developed rapidly and have achieved remarkable results. Emerging science and technology such as intelligence and industrial automation have been integrated into industrial development. Compared with developed countries abroad, we have achieved notable results. However, as far as the current status of China’s smart manufacturing is concerned, the gap between China and developed countries is still very large. If we observe China’s smart manufacturing in a more macroscopic scenario, we will find that there are many constraints affecting its development. . In light of this, we also need to think and act in the development of smart manufacturing. First, the constraints of production mode and materials In this paper, we clarify that intelligent manufacturing is oriented to achieve “individual production” as a product strategy that promotes the competitiveness of the company itself, and adopts information technology to transfer data from all aspects of production to the management system, and “enhance” through dynamic optimization. Quality, reduce costs, and shorten product delivery cycles." Mechanical rigidity constraints At present, many industrial production methods are mostly based on existing raw materials, whether metal materials, plastic materials, fiber materials, or semiconductor materials, and are processed through a certain process of cutting, forming, weaving, etc., and many of these processes are mechanical. There are constraints. For example, pharmaceuticals, we can not carry out "single insertion" to achieve flexible customization, because each batch of drugs need to be cleaned in production environment before another production, many parameters affecting the quality of production can not be achieved online adjustment, which will inevitably lead to Bad products, and mass iterations require batch-based data to achieve improvement. Research on the Fusion of Material Technology and Manufacturing The 3D additive printing technology in smart manufacturing is a hot spot in China's smart manufacturing, but there are still bottlenecks in terms of materials, processing speed, and cost. There is no breakthrough in material science and technology, and traditional production processes cannot achieve breakthroughs. For example: Energy saving is the most effective process energy - through the radical improvement of the process, with new production methods to achieve energy reduction. However, it is difficult to improve the process. One example is that although digital printing is very good, there is currently no innovative progress in the materials and processing of ink jet heads, and domestic advancement in the manufacturing field cannot be achieved in this direction. Others such as ink technology, viscose technology, high-performance metal materials, special fiber materials, etc., have similar problems in their respective applications. The lack of innovation in basic and new materials will cause our manufacturing industry to remain under control in these areas, fail to truly realize the upgrading of the manufacturing industry, and will have stronger capabilities in information and automation, and will not be able to produce more competitive products.
