| Abstract: | Long needle like ports are used widely in textile machinery. Because of coldworking,a necessary process during manufacturing, there are residual stresses in the parts, and normal heat treatment will cause bending deformation at the bar of the parts. The paper discribes a pretempering method on sewing needles as an example, which testifies that the way is correct, and canbe put into practice. |

| Keywords: | pre-tempering long needle like parts bending deformation |
