1. Angle 1 degree * height 1mm=0.0174mm (segment difference);
2. 1 strip = 1 wire = 0.01mm;
3. Confirm the ejection direction of the front and rear molds;
4. All product drafts are drafted by reducing glue, if you want to add glue, the customer must confirm it before drafting;
5. If there are rounded corners on the drafting surface, remove the circle and then pull it back, and then rewind the same rounded corners (the product will be slightly changed after drafting, normal);
6. The function and appearance of the product should not be affected after drafting;
7. The draft angle of the product is usually 3 degrees, but it depends on the height of the draft surface, generally the level difference is about 0.05-0.1mm, not too big;
8. The smallest end of the rib after drafting cannot be less than 0.6mm, otherwise it is difficult to form;
9. The drawing direction of the structure should also be drawn.
10. The draft angle depends on the appearance requirements of the product. When confirming the angle of drawing (such as sun pattern, bright surface), the deeper the sun pattern, the larger the draft angle. Generally, the draft angle refers to the draft parameters in the pattern board. Perform a draft.
11. Except for 1mm, the straight face does not need to be drawn, and the rest of the straight face must be drawn.
