Binzhou Zhengdao Mechanical Manufacturing Co., Ltd.

Compared with the traditional cast aluminum piston, the ductile iron piston has greater strength and smaller expansion coefficient, so the piston length can be reduced as a whole, so that when the diesel engine is working, the piston stroke is lengthened, the combustion gas expands more fully, the output power increases, and the economy is better. The company has developed and used sand casting to produce ductile iron piston castings, with high dimensional accuracy, excellent performance and low cost.
