|
For zinc machines only. Tail rod diameter. This is the small rod sticking out of the top of the machine. On B&T hot chamber machines this is usually 1" standard. This reduces the effective piston area. ________________________________________________________ |
|
Also on zinc machines. The stroke is a fixed number. Shot cylinder stroke ________________________________________________________ |
Note: By providing the above, metal at the gate (P1) becomes a fixed number for zinc machines. |
|
Maximum intensifier pressure. (PSI) This can be calculated or from pressure traces. ________________________________________________________ |

|
For UBE machines or Lester machines with pre-fill system only, provide the shot rod diameter. ________________________________________________________ |
