There are many kinds of classification methods for copper castings: according to their metal materials, they can be divided into cast copper parts, iron castings, copper castings, cast aluminum parts, casting magnesium parts, zinc casting alloy parts and cast titanium parts. And each type of castings can be further divided into different types according to their chemical composition or metallographic structure. Such as copper casting can be divided into bronze, copper, aluminum bronze, brass, copper, phosphor bronze, copper, beryllium copper, aluminum brass copper pieces; cast iron can be divided into the gray iron, ductile iron, vermicular cast iron, malleable cast iron, alloy cast iron cast molding method; according to the different, can be divided into ordinary casting sand casting, metal casting, die casting, centrifugal casting, continuous casting, investment casting, ceramic mold casting, Electroslag Remelting Casting, casting etc.. Among them, ordinary sand castings and centrifugal casting are most used, accounting for about 80% of the total output of the castings. Our factory mainly produces cast copper parts, cast aluminum parts, cast iron parts, and cast zinc base alloy parts.
Castings have a long history of application. The ancient people for casting coins, sacrificial and weapons, tools and some appliances. In modern times, castings are used mainly for machine parts, and some precision castings can be used directly as parts of machines.
Castings have a long history of application. The ancient people used coins, bronze casting, sacrificial weapons, tools and some appliances. In modern times, castings are used mainly for machine parts, and some precision castings can be used directly as parts of machines. The casting has a large proportion in the mechanical products, such as tractors, casting weight accounted for about 50 of the weight of the machine to 70%, agricultural machinery accounted for 40 ~ 70%, machine tools, such as internal combustion engine in 70 ~ 90%. Among all kinds of castings, the largest variety of castings used for mechanical casting, the most complex shape and the maximum amount, accounts for about 60% of the total output of the castings. The next is the steel ingot mould used in metallurgy and the pipe used in engineering.
