In general, an EDM surface will produce a good texture and may improve release from the tool during part ejection.
To aid in release, the cavity or core may be coated with a release coating such as PTFE impregnated nickel after it has been given a sandblast or EDM finish.
Valve gates do not require the material in the part to freeze before the valve is closed and hold pressure is released.
