K-factor for plastic | SOLIDWORKS Forums

12/12/2013· K factor can vary greatly with plastics, as there are alot of factors that can come into play. The type of benders that are used. i.e is the material being heated on both sides or just one. is the heat hotter on top or bottom. are you bending towards the heated side or away from the heated side. how big is the area being heated, and how does this relate to the radius being bent.
