Give me how much it's bent, where, material type and Ys and the dimensions and I'll tell you how much plastic you have bent it. My guess is it's a very low number. Do you realize that in almost any shaft manufacturing, the parts are bent and straightened during the manufacturing process? I have been in heat treating facilities where there are entire departments dedicated to straightening shafts.
