(8) Processing sequence:

¢Ù Shearing spinning (point A) followed by multiple deep drawing spinning ¡ú ¢Ú Trimming ¡ú ¢Û Curling;

9) Processing points:

1) Pre-bend the outer edge of the rough piece to prevent wrinkling during spinning;

2) Start spinning by shearing to point A, and then use multiple passes of deep drawing and spinning;

3) Consider the shape of the profiling plate to make the forming at point A smooth transition;

4) During the deep drawing and spinning process, use a back pressure roller if necessary. But be careful to avoid damaging the material. Use a soft back pressure roller if necessary

5) Use a hard plastic spinning wheel and a steel core mold, or a steel spinning wheel and a resin core mold;

6) The trimming knife should be made at a 15¡ã bevel to facilitate the curling of the flange after cutting.
