The production capacity was increased from 100,000 units to 150,000 units, and the foreign exchange earned through exports exceeded 800,000 U.S. dollars; the reserve of finished products was reduced from 3,500 tons to 2,100 tons, a drop of 40%; the occupation of working capital was reduced from 14 million yuan to 7.5 million yuan. The drop rate was 53%; the equipment completion rate reached 98.4%; the equipment disposal rate dropped by 57% compared with the past; the overall scrap rate was controlled below 45%, ranking the leading domestic level, and the economic benefits grew at a high speed. Zhang Dinghua, vice chairman of the All-China Federation of Trade Unions, inspected the FAW foundry and highly appraised the “four improvements,” and named the foundry worker typical of Yong Lai as “the most lovely person in the new era”. The Workers’ Daily reported on FAW’s experience in promoting lean production methods. The specific practices of the “Four Improvements” of the lean production method implemented by FAW foundry are:
