Extrusion granulation is one of the most important components of the molding industry

and is exhibited both in the talent training scheme and core competence assessment in polymer materials. Aiming to help students to highly master the knowledge and related skills of the extruder (extrusion granulation)

this paper introduces a kind of new teaching mode

which construct an unreal extruder (extrusion granulation) by using virtual reality technology. Importantly

we have owned the software copyright of the "Extruder (Extruding Granulation) Craft Simulation Software V1.0" (NO. 2019SR1039132). As a result

students can learn the whole extrusion granulation craft on computer rather than in person. Additionally

the new teaching mode will further stimulate students' interest in learning professional knowledge and helps to improve the ability to operate in real and analyze-solve problems.
