Material Testing and Data Preparation

What Is Material Characterization?

Material characterization is the process of measuring how a polymer or composite material behaves under different temperatures, pressures, shear rates and loading conditions.

Moldex3D simulation accuracy depends strongly on the quality of the material data used in the analysis. Generic or incomplete data may not represent the actual behaviour of a specific grade, compound, filler level or supplier formulation.

Material characterization services generate the rheological, thermal, mechanical and kinetic properties required for filling, packing, cooling, curing, fibre orientation, stress and warpage simulations.
