Calculation Formula for Ejection System Area

 

We only need to modify the values in the green and gray boxes. We only need to compare the value in the orange box with the value in the gray box. If A > B, it indicates that the area of the ejection system is insufficient, and the product may have ejection-induced sink marks or cracks, requiring additional ejection pins or blocks. Conversely, if A < B, it indicates that the area of the ejection system is sufficient.

This calculation formula is for reference only,  It is mainly intended for products with multiple ribs, to prevent the ejection system from being designed with either too many or too few components during mold design.This is only valid when the ejection mechanisms are evenly arranged, resulting in a balanced ejection of the product.This formula is for reference purposes only.



there are the printed analysis and judgment results below.
