The baking process is required for curing of structural and cosmetic seals and proper heating is a must. Unequal or insufficient heating can result in different seal related quality problems. The uniform paint thickness at spray painting is critical as well. Too much or too less can cause orange peel or fish eye problems. All these problems can be predicted and planned in parallel with car design using Ansys tools. Multiphase fluid flow, electrostatics, particle tracking, wall film modeling, conjugate heat transfer and radiation, in other words the physics behind car paint shop can be modeled and tuned for perfection. Recent developments in Ansys tools also enables processing of complex and large automotive CAD geometries. Ozen Engineering has completed numerous consulting projects in regards to paint process modeling and can help companies paint shop planning. Ozen Engineering makes use of cloud computing as an enabler for large and long transient runs.
