If the ESFR is providing more water delivery density than would be required by what NFPA calls for in delivery density, then yes, ESFR will be sufficient (or more than sufficient) to put your solid commodity fire out. However, if you have a spray fire with hydraulic fluid (proclivity of the fluid catching on fire depends on its flashpoint and auto-igntion temperature among other factors), an ESFR or NFPA sanctioned system is not going to put it out. You will need dry-chemical and maybe foam. Shutting down the power to the injection molding machine should end the spray fire, in which case you just have a pool fire. If the hydraulic fluid is a Class III-B, which many of them are, then the ESFR or NFPA system should keep things cool enough until the unconstrained pool fire either burn out [ several minutes], or hand extinguishers can be brought over for the kabosh..
It would be good to have several 25-lb manual extinguishers, apply quantity as suitable to the hazard. Hopefully they will never need the dry-chemical extinguishers, but...
