For general, in-home use, many ceiling fan blades are made from particleboard or medium-density fiberboard (MDF). A method of making a sheet metal fan blade having a flattened mounting pad. The final blanking step with such prior-art procedures has involved the removal of portions 24 and 26. As the hot air rises up, the blades of the fan slice this air and push it down. They cool people effectively by introducing slow movement into the otherwise still, hot air of a room. Most fans don’t win awards, because most fans aren’t the result of a Herculean feat of engineering. PLC controlled paint system monitoring, reciprocator movement, bell applicator for paint, conveyor speed etc. 2.  Contact Us   | This invention relates to a process for forming a sheet metal fan blade of a type particularly adapted to be employed in conjunction with the fan in an automotive cooling system. The numeral 16 denotes a centrally running rib also extending from the radially innermost portion of the blade to a central portion thereof. This being a continuous process causes the air in the room to circulate in the entire room. The blade is to be attached to a flat spider arm of a fan hub.
