HPDC Pathshala
Keep Learning Till Death

Filling Ratio in HPDC is one of the most important but often misunderstood parameters in high pressure die casting. In many plants, filling ratio is treated as a simple percentage value, but in reality it directly influences air volume in the shot sleeve, wave formation during the first phase, slow shot velocity, fast shot demand, cavity pressure, flash tendency, gas porosity and overall process stability. In this live technical webinar, HPDC Pathshala will explain filling ratio from a practical engineering and shop-floor decision-making point of view. The session will move step by step from basic concept and calculation to real process impact, helping participants understand why a higher filling ratio is not always better and why sleeve diameter selection must be matched with actual machine capability. The webinar will also cover the relationship between filling ratio and critical slow shot velocity, how air entrapment starts inside the shot sleeve, how incorrect wave forma...;
