Hi everyone, I have to design a plastic tube that will be glued on a carbon tube. The assembly will then be fitted into an aluminium hub in which it will rotate (I have attached a drawing). I would like to have the plastic tube injection molded rather than machined for cost reduction. But I need to have a draft on the inner part of the tube so it can be molded. But with a draft I feel like I will not have a titght fit between the carbon shaft and the plastic tube, and I am a bit afraid that I will not acheive good alignement between the axis of those two parts. What is your feeling, Have you ever seen an injection molded tube without draft ?
