3). If this reads like a sermon, then so be it. The Good Running System is a Good Cause that deserves the passionate concern of the casting engineer. Too many castings with hastily rigged running systems have appeared to be satisfactory in limited prototype trials, but have proved to have disastrous levels of scrap when put into production. This is normally the result of surface turbulence during filling that produces nonreproducible castings, some apparently good, some definitely bad. This result confirms the nature of turbulence.

All need mechanisms (not shown for clarity) to reduce the velocity of the melt. 20 Castings Practice: The 10 Rules of Castings in this section is to evaluate gravity filling, to see how far it can meet this difficult set of criteria. Requirement 3 for good gating is important: only liquid metal should enter the casting. Thus all bubbles entrained by the surface turbulence characterizing the early part of the running system should have been eliminated by this stage. If the running system is poor, and bubbles are still present, their rise and bursting at the liquid surface in the mould violates Rule 4.

Clearly this system violates one of our principal rules, since the metal is now entering the mould above its critical speed. The resulting splashing and other forms of surface turbulence inside the mould introduces its own spectrum of problems, different from those of the unpressurized system, but usually harming both the quality of the mould and the casting. Thus neither the unpressurized nor the pressurized traditional systems are seen to work satisfactorily. This is a regrettable appraisal of present casting technology.
