用EPC法（亦称消失模铸造）生产球铁曲轴、管件和阀体，较好地解决了球铁中常见的铸造缺陷，并提高了铸件的内在和表面质量以及尺寸精度。
The EPC method, also known as lost foam casting, produces ductile iron crankshafts, pipe fittings and valve bodies that better solve the common casting defects in ductile iron and improve the inherent and surface quality of casting as well as dimensional accuracy.
