Abstract: In order to solve the bottleneck problem of polymer product processing striving for micro scale and precision or macro scale and complication in modern manufacturing, a concept of differential and integral method applied in advanced manufacture of polymer materials is brought up. On the base of this concept, principles of injection molding, extrusion, electrostatic spinning, nano-composite processing and structure innovation of polymer products have been studied; a series of new methods of polymer processing and molding, new equipments, and new technologies of product application have been invented. Some industrial application results prove that, the concept of differential and integral method applied in advanced manufacture of polymer materials is a valuable guide to break through the restriction of traditional manufacturing mode, and to develop new method of polymer processing and new technologies of polymer products application.

Abstract: FEM analysis of flow field in nano-laminated coextrusion die is introduced. Nano-laminated coextrusion die is a new type of laminated composite generator which is based on the principle of the melt calculus. The distributions of pressure field and velocity vectors are obtained and analyzed. The result using finite element simulation software Polyflow shows an improvement in structure of die as well as better quality for melt flow characteristics. The paper is helpful in design and optimization of coextrusion die and process.

Abstract: In this paper, we propose a resin-based composite materials and its preparation process, because traditional composite materials craft has shortcomings such as labor-intensive, low productivity and quality unstable. It can eliminate the need for mold processing and manufacturing sectors, and the manufacturing costs reduce significantly. Reinforcing materials can play a full role to enhance, and the volume of products can be great without the restrictions of traditional processing equipment. The speed of product replacement is accelerated.
