On hot sticky summer days nothing can beat the breeze you feel from a ceiling fan. (Trust me I should know I live in Florida) A ceiling fanâs direction in the summer should be rotating counter clockwise or forward to produce a Wind Chill effect by the downward airflow. The thermostat wonât actually change but the room will seem several degrees cooler due to the wind chill factor.
Reaction injection molding. Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Common items made via RIM include automotive bumpers, air spoilers, and fenders.
