All kinds of casting wheel guard Hom supply, the most varieties casting machinery, shape the most complex, the amount is also the largest, accounting for about 60% of total production of castings. Followed by the ingot mold and metallurgical engineering pipeline, as well as some of the tools of life. Casting is also closely related to daily life.
