Will Plastics Wilt Under The Heat of the Lights?

New 3-D Thermal Prediction software can help designers of automotive headlamps predict the thermal stresses, distortions, and dimensions of plastics exposed to high-intensity automotive lighting (up to 400 F). The new software is used by engineers at GE Plastics Automotive, Southfield, Mich., to choose resins for headlamp applications and to optimize designs for specific resins. The software predicts the temperature of the air encapsulated in the headlamp, as well as its convective movements, in order to anticipate temperatures at every point in the headlamp. The present 3-D Thermal Prediction process takes GE about eight weeks to complete. GE is working to reduce that to three weeks.
