Apex Technologies is heavily involved in consulting activities for the polymer processing industry. It is therefore natural that the company established goodl relationships with Polyflow SA,  which   is a leading company specialised in develppment of  simulation techniques for the polymer and rubber  processing industry. The main product, the finite element fluid flow simulation code Polyflow is extensively used by Apex Technologies in the simulation of extrusion and blow mouldind processes.

 

 

Main features of Polyflow code:

Simulation of general non-Newtonian and visco-elastic fluids
Free surfaces
Direct and inverse extrusion simulation
Multi-material (coextrusion) analysis
Blow moulding, film casting, etc.
Parallelized efficient solver
Optimisation techniques
Many more ...
Optimisation of extrusion dies: Calculating the flow velocity distribution at the die exit for different die configurations; optimising the geometry to obtain more uniform velocity profile
