The advantage of gravity casting technology
Item	Gravity casting technology	Foundry casting technology
Product quality	The structure of the casting is compact and both of its inside and outside surfaces are smooth . The  sizes of castings are concordant . The fine machining speed is fast  and polishing rate is high .	There are some dregs and sands on the surface of the castings. Its structure is loose and both of the inside and outside surfaces are rough. The sizes of castings are not concordant . The fine machining speed is slow and polishing rate is low.
Qualified rate	92%~98%, high qualified rate	High rejection rate
Labor productivity	It needs only 7 persons .	It needs more than 14 persons .
Pollution situation	Casting temperature is low . Its pollution and noise are also low .	It produces smoke . Its pollution and noise are high .
Operation situation	Simple and easy learned operations and  skills can  be  mastered in 2 hours. Its labor consumption is low .	Its operation is difficult to learn, and it is high in both labor consumption and labor intensity
Cost accounting	Its labor cost is low . Copper consumption and spoiled  product r ate are low .It can increase production quantity and product quality is stable .	Its labor cost is high .Copper consumption and spoiled  product rate are high . Production quantity is low and product quality is not stable
