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.
