Abstract: In this paper, an integration technology of extrusioninjectioncompression was proposed, in which a secondary clamping by innovative toggle direct pressure was used, and injection molding problems caused by the large gas content and poor fluidity of the waste melt were solved by injection compression molding process.Meanwhile, solid waste plastics could be converted to products directly by using the intermediate connecting device that could coordinate and automatic linkup the “continuous” and “intermittent” process between extrusion and injection compression molding.In this way, it achieved the purpose of efficient processing and highvalue recycling of solid waste polymer materials by greatly reducing processing cost and improving recycling ratio of solid waste polymer materials.

Key words: solid waste plastic, integration of extrusion-injection-compression, injection compression molding, recycling
