Based on rubber processing research, this article utilizes computer technologies such as Unity3D and 3Dmax to construct a three-dimensional scene and process flow of the rubber mixing workshop. It designs and develops a virtual simulation system for the rubber mixing process. This system features perspective observation of the internal process, supports free movement for visitors, has strong interactive simulation capabilities, and professional page design. Taking the F270 type internal mixer as an example, the system demonstrates the structure and working principle of the main equipment and achieves interactive operation, fully reflecting the advantages and characteristics of combining rubber mixing technology with a virtual simulation platform.
