Present Research Situation and Development Trend of Soft-hard Co-extrusion with Special Plastic Profile;

The paper introduces the coextrusion technology,equipment and mould for the double-coloured special plastic profile with the double-coloured transparent plastic handle of the screw-driver as an example.

Polyflow-based design of sprue runner in extrusion tooling outlet for extrusion forming the function part of plastic profiles;

Study on Stability of Extrusion Dies with Incoordinate Depth of Plastic Profiles;

Numerical Simulation of the Extrusion Process for Plastic Profile and Design Optimization of Extrusion Die;

Numerical simulation of cooling strain in extruded hollow plastics profiles was made using Ansys FEM software, the reasons and influencing factors of profile's distortion were obtained.

The affection factors of surface radiance of plastics profile were analyzed, which including extrusion fixture, material formula referring to the choice of lubricant, impact modifier, CaCO 3, thermal stabilizer technological conditions of extrusion and mould configuration.

The advantage and application example of the plastics profile are introduced.
