In the practice of 1 kg gold ingot production by one-stop automatic casting,in order to solve the problems including poor efficiency of material preparation,low level of mass weighing automation,low product pass rate at the early stage of mould usage,and short service life of mould,the paper simplifies material preparation operation,automates mass weighing,improves product pass rate,prolongs service life of mould.As a result,the efficiency and product quality of gold ingot production by one-stop automatic casting are greatly improved.Gold ingot production in 8 h of single shift is increased from 300 kg to around 500 kg,gold melting loss is reduced from 0.015 % to 0.002 5 %,gold ingot pass rate is increased from 82.65 % to over 98 % and the service life of mould is increased from about 70 times to about 150 times.
