China Orotrim Machinery company is a research, development, manufacturing as one of professional manuf- acturer of plastic machinery.Since its inception, has always been dedication to "high tech machinery" in the re- searchand development.And efforts to build their reputation as the industry's first brand.Companies aim at the world'smost advanced plastic machinery technology, in-depth research,and have developed a lot of original techniques,some of the world's first, and more to fill the domestic blank.That have already submitted a number of patents,has developed a unique market, competitive advantage. We are still a few company in the world, who use of CFD-FLUENT techniques to improve the design of plastic equipment, including extruders and dies. Production of plastic products, equipment must meet the profitable production rate. Only high-yield to low-cost, can be profitable. Production rate of our system can not be com- paredto other companies, high yield than domestic company equipment 3 to 5 times.POLYFLOW finite element method is used mainly for viscous and viscoelastic fluid flow pro-blems for CFD simulation software. As a com- ponent of FLUENT, it has a strong solution of non-Newtonian fluids and the ability of nonlinearproblems,and its flow with a variety of models can solve the polymer, food, glass, etc. encountered in a variety of processes such as temperatre / Non-isothermal, two-dimensional / three dimensional, steady / unsteady flow problems, can be used for extrusion, molding, hot pressing and other forming methods of simulation.
