Problems solved by technology

[0005] In the actual production process, it is difficult for the resin introduced into the system to be completely free of inclusion gas, and the inclusion gas does not move uniformly with the resin in the flow field. It will take a lot of time to optimize the process and control defects through a large number of experiments. A large amount of manpower and material resources will have a huge impact on production costs. Therefore, computer simulation technology is used to predict the flow and enrichment of inclusion gases, and on this basis to achieve process optimization and control of pore defects. The quality of the production is crucial to reduce the cost of
