Among the various ownership enterprises, the large-scale annual output of die-casting parts is 10,000 tons, the maximum annual output is 60,000 tons, the medium-sized annual output of die-casting parts is about 5,000 tons, and the small-scale annual output of die-casting parts is also several hundred tons. . The proportion of various die-casting parts in the total amount of Ol hap bilong dai-kasting, aluminium aloi i save kamapim samting olsem 83%, zinc aloi i save kisim 15%, na ol i bin lusim ol gol akaun bilong 2%, we samting olsem 5.6 milien tan aluminium aloi dai-kasting hap i bin kamap long 2014.
The main output of die-casting products is mainly automobile and motorcycle parts. The die-casting parts used in each automobile are gearbox housing, cylinder block and crankcase quasi-die casting. The average die-casting part of each car is 75 kg, total weight. It accounts for more than 50% of the total production of die-casting parts in China.

In the CNC center, five-axis and three-axis CNC machine tools are used for machining. The design of such high-precision machine tools uses a series of high-precision pneumatic actuators such as cylinders. Affected by traditional processes, most of the finished products produced by casting manufacturers often have high defect rate, and the processing accuracy is difficult to meet the requirements, and such problems have not been effectively solved.
