Gang Trim Die, or O.D. only Trim Die
The gang die is intended to blank out large quantities of parts from their connected sheet of flash. This type of tooling is particularly useful in trimming parts that are otherwise difficult ot remove from a mold pin or where a large number of closely trimmed parts are required. In referring to this type of tooling a description of 2 rows of 20 O.D. or 5 rows of 10 O.D. is used. The rows refers to the entire length of the sheet and the 20 is how many parts are in this row. Therefore in the first case 40 parts are to be punched out at a time and in the second instance 50 parts at a time.
