Some innovative technologies for resins,additives,injection machines and extruders show- cased on the 21~(th) International Exhibition on Plastics and Rubber Industries were introduced.

The research progress in using supercritical CO2 as a plasticizer to reduce the viscosity of polymer melt during extrusion molding and as a foaming agent to make microcellular foams is introduced and the further researches are pointed out.

In the process of PVC low foaming solid sheet extrusion molding,it is critical to control the folw and foaming of the molten polymer.

The self-made new type of hydraulic vibration extrusion equipment was adopted to study the rheological behavior of high density polyethylene(HDPE) under vibration extrusion molding.

It introduced the extrusion moulding technology of pvc surface-crusting low-foamed wided door sheet.

This article is about the new development in extrusion moulding field, and introduces the new extrusion moulding technique and equipment at K2001.

This paper introduces the production technology of the injection and extrusion moulding of Nylon 11.

Studies on the Formation of Homogeneous Ploymer gas Phase in Microcellular Foam Extrusion;

Novel Method and Epuipment for the Polymer Extrusion Processing;

The impacts of magnetic powder sizes and contents to the fluidity of bonded NdFeB for injection molding and extrusion;

The analysis and discussion were made on various processing-control factors in extrusion forming procedures with the modified extinction ABS resin which could be made by mixing SBS and ABS resins and obtaining their granulations.

Based on the characteristic of the plastic profile extrusion process and the theories of rheology and hydrokinetics etc.

In the dissertation high-temperature corundum honeycombed ceramic regenerative body was prepared by an extrusion process, a-Al2O3 minute powder as main raw material, clay, CMC etc as plasticizers, tung oil etc as lubricator.
