Body Dash Number

Flush Head Styles NonFlush  Head Styles
Overall Panel Thickness  minus

Bottom Skin Thickness  minus

.010 Springback  Factor.

Example:

.750 – Overall Panel Thickness – .020 /.730 – Bottom Skin Thickness – .010/.720 – Springback  Factor =- Maximum  Body Length

Core Thickness  plus Top Skin

Thickness  minus .010

Springback  Factor.

Example:

.690 – Core Thickness +.040 /.730 – Top Skin Thickness – .010/.720  – Springback  Factor =  – Maximum  Body Length

 

2. Select Body Dash Number from the table below based on Maximum Body Length determined in Step 1; round down to next lowest value.

Example: .720 Maximum Body Length = -70 Body Dash Number.

Body Dash Number M aximum Body Length
-30 .335
-40 .350
-50 .450
-60 .550
-70 .650
-80 .750
