Summary:The effects of casting conditions on the flow length of thin-walled diecastings for ADC 10 alloy were investigated using a 90 metric ton locking force cold chamber type die casting machine. The flow length increased with the gate velocity, however, it was more or less not affected by the pouring temperature and the die temperature. The flow length decreased as the shot-time-lag increased. The fluidity of die castings drastically improved with powder lubricant compared with conventional oil lubricant. The fluidity of the thin-walled die casting was aftected by abnormal microstructures, such as coarse α phase and scattered chill structures. When the area ratio of the abnormal structures was above 0.3, the flow length gradually decreased due to increasing apparent viscosity.
