MMI - Design and simulation services

By combining Mechanical simulation, Material modeling and Injection molding simulation, (MMI), TECHNYL® customers can understand the real behavior of their parts’ functionality before going into production. This enables engineers to create stronger, lighter and more cost-effective solutions without resorting to a trial-and-error method, while avoiding overdesigning parts

The MMI integrative structural simulation process starts with an injection molding simulation considering all relevant processing parameters to determine and to export the glass-fiber orientation in the part. To make the orientation data usable for structural simulation software, two automatized steps need to follow.

Firstly, the fiber orientation tensor data is passed on to a micro-mechanics software program like Digimat®. Using an orientation dependent mechanical material model of the respective TECHNYL® grade, the Digimat® software automatically calculates all local material properties of the part's finite element mesh for the given environmental conditions. In this second step the material data file is exported and can be integrated seamlessly to allow an anisotropic structural simulation of the part.

Using the MMI approach, an implementation of fiber-orientation-based TECHNYL® material data into most commercial FEA/CAE simulation software is easily done using available tools from Digimat® and plug-ins integrated by the respective simulation software producers. Combining DOMO’s polymer science-based material data with commercially available simulation software, the performance of injection-molded parts can be predicted in a wide range of realistic use-cases. 

Based on our advanced material characterization and material models, DOMO’s MMI approach offers advanced integrated CAE capabilities to TECHNYL® customers. This service is accessible either by simulation as a service by DOMO experts, or TECHNYL® customers can run their advanced simulations in-house relying on the material data supplied.
