Is pressurized filling important? Does the process increase my capability and ease of casting?
Pressure is always important. The height of your sprue is currently your available pressure. Patterns too high in the mold may fill too slowly or not at all… mis-run! The number one cause of riser connection shrinkage is actually: poured short risers mis-run! With the Herron Casting Process, pressure may be set at the optimal level to fill those hard to fill castings. The gates are then designed to freeze before burn-in begins to occur, leaving conventional risers to feed at standard pressures. YES! Capability is increased and ease of casting!
