From December 15th to 18th, 1983, the Ningxia Heavy Industry Department was commissioned by the Agricultural Machinery Bureau of the Ministry of Machinery to preside over the appraisal meeting of the aluminum piston-inlaid wear-resistant ring at the Wuzhong Parts Factory. Attending the meeting were 30 units and 54 delegates. Aluminum piston inlay wear circle technology Department of Agricultural Machinery Department issued 80 years to the Wuzhong Parts Factory, Changsha Zhengyuan Power Parts Factory, Shanghai Piston Factory scientific research tasks. Based on the introduction of AL-Fin process technology data from the United Kingdom’s Wilfri Co., Ltd., the three plants combined their existing conditions, after more than three years of experimental research, digestion, mastered the introduction process.
