Successful deep drawing depends on many factors. Ignoring even one of them during die design and build can prove disastrous. However, regardless of the many factors involved, the most important factor to a successful deep drawing operation is initiating metal flow. The following are key factors affecting metal flow, and each of them should be considered when designing,building, or troubleshooting deep drawing stamping dies. 

1. Material type

2. Material thickness

3. N and R values

4. Blank size and shape

5. Part geometry

6. Press speed

7. Draw radii

8. Draw ratio

9. Die surface finish

10. Die temperature

11. Lubricant

12. Draw bead height and shape

13. Binder pressure

14. Binder deflection

15. Standoff height
