Working with the Rescue Community
- We proactively participate with the firefighting and rescue community to promote automobile safety.
- Their experience and training sessions indicate that standard rescue tools can be used for extrication in the event of an accident.

Building on SABIC Innovative Plastics’ extensive materials, application design and molding experience, Exatec’s team of engineers utilize predictive engineering analysis early in the application design and development process in order to optimize both the molding and coating processes as well as the end-use performance.
Advanced simulation techniques include molding process simulation, thermal expansion and dimensional stability, structural, stiffness and NVH analyses and thermal modeling. |
Injection molding process simulation can assist in developing proper tooling design and gating strategy to ensure high quality optically clear and dimensionally accurate parts. Analysis techniques include simulation of both injection-compression and two-component molding.

Structural Analysis
Thermal expansion, dimensional stability, structural, stiffness and NVH analyses can be performed to predict the mechanical behavior of an application. Analysis techniques consider the basic properties of the first and second component materials, the attachment points and the thermal or mechanical loads applied. These advanced finite element analysis computer simulations can guide designers to the most effective choice of materials, part thickness and geometry. |

Thermal Modeling
Thermal analyses are used to study the effects of thermal load on the interior of a vehicle. Computational Fluid Dynamics (CFD) analysis techniques consider the basic thermal properties of the first and second component materials as well as the applied cooling/heating or solar load. These computer simulation models can examine the effects on passenger comfort and HVAC load. |
