Accumulator pressure for dry shot. ________________________________________________________

(This is the gage reading just prior to the shot)

 

Maximum slow shot velocity, inches / second,(IPS), (millimeter / second) ________________________________________________________

 

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. ________________________________________________________
