What is CONVERSE?

CONVERSE is an easy-to-use software that bridges the gap between injection molding simulation and mechanical simulation. It leads to significantly more reliable results with regard to stiffness and strength of short-fiber-reinforced injection molded parts as well as more realistic simulation of the thermo-mechanical behavior of molds and inserts. CONVERSE enables the user to consider anisotropic part properties like for example fiber orientations and residual stresses in a mechanical simulation of the molded part as well as considering process loads like molding pressures, temperatures onto inserts or the mold itself.

  • Consideration of the influence of gate positions onto the mechanical behavior of the part (position of weld lines)
  • Improved mold design for molds with critical thin cores
  • Improved part design for parts with pressure- or temperature-sensitive inserts
  • Easy to use also for occasional users
  • See-through and open data handling

Applications

CONVERSE is a useful tool for all kinds of injection molded plastic parts. Typical applications are but not restricted to:
  • Evaluation of stiffness and strength of fiber-reinforced plastics parts
  • Evaluation of thermo-mechanical stresses in inserts or over-molded electronic devices
  • Evaluation of mold deformations and stresses CONVERSE can be used in all branches of industry who have to mold plastics parts and/or evaluate the mechanical properties of the manufactured components.

Modules

CONVERSE is a software that bridges the gap between injection molding simulation and mechanical simulation by interfacing with both types of software. It allows for 3D-visualization and manipulation of imported models and results and allows for a variety of mapping including fiber orientation, pressures, temperatures, thickness, and stresses and exports the data in a ready-to-use FEA input file. For short-fiber-reinforced parts it provides an anisotropic material model and delivers all necessary prerequisites in order to consider local fiber orientation in a subsequent FEA. Thus the prediction capability of the mechanical FEA can be improved significantly.

Specifications

CONVERSE is available for Windows 64-bit machines.
