Last week, we shared an overview of Datwyler's in-house simulation capabilities. Today, we invite you to dive into peer-reviewed research from our Simulation Team, recently published in the Journal of Rheology. The paper introduces a new methodology for characterizing the viscosity of uncured rubber compounds, tailored to commercial compression molding applications.   It tackles a long-standing practical challenge: how can the viscosity of uncured rubber compounds be rigorously characterized to accurately reflect their flow behavior during compression molding?   Unlike conventional rheological approaches, the proposed methodology captures how rubber compounds behave under real compression molding conditions using a simple uniaxial compression (squeeze flow) test.   By combining analytical modeling with targeted experiments, we extract shear-rate-dependent viscosity and yield behavior across a wide operating range — transforming a standard test into a robust, simulation-ready material characterization framework.   This reflects how we approach R&D at Datwyler: combining deep material and process expertise with applied engineering and advanced simulation to translate rigorous science into practical solutions — enabling faster development cycles, more reliable processes, and enhanced manufacturing performance.   📄 Read the full paper (open access): https://lnkd.in/g_r36yGm   💬 Have a complex compression molding challenge?
