Pressure to fill – 8,675 psi. 97% JES3.2—Analyze Mold Flow and Select Optimal Scenario通过模流分析选择最佳方案 This plot shows the pressure distribution at 97% switchover by volume. Pressure to fill – 8,675 psi. 8675.6 Avoid Good Part is poorly balanced and has large distribution of pressure 产品填充不平衡且压力差较大 Part is very well balanced and has small distribution of pressure 产品填充平衡且压力分布均匀 Co
