Abstract: In order to improve the experimental teaching effect of polymer injection molding process, a web-based virtual simulation experiment platform for injection process is designed and developed. It is based on the cloud concept, using the browser as the platform, the code as the tool, and using internet technology. The development process is as follows: first make various kinds of experimental materials such as videos, animations, documents, etc., then use a code compiler to write control command codes, and finally render through the browser to complete the preliminary design of the web site. The virtual platform includes three elements: material, process and equipment (mold), integrates and optimizes multimedia resources such as documents, videos and animation, and provides teaching management services and simple human-computer interaction. After debugging,modification and using, the feedback from teachers and students is better, which effectively promotes the teaching reform.
