JINAN WELTOP MACHINERY EQUIPMENT CO.,LTD.

Advantage: 1.There is almost no metal consumption at inject system and gating system, so production rate improved much. 2.There is no core when produce hollow castings so greatly improve the metal filling capacity, lower the ratio of wall thickness to length or diameter and simplify the process of sleeve and pipe production. 3.High density, less of defects like pores and slag, high mechanical property. Easy to manufacture cylinder or sleeve type composite metal castings such as steel back copper sleeve, bimetallic roller, thin wall castings.

molten metal is poured into a hollow cylindrical mold spinning about a horizontal axis. The centrifugal force distributes the molten metal and shapes it into a tubular/cylindrical forms. The high  forces involved in this casting method means that the less dense materials including impurities are forced into the center where they can be subsequently removed and gas related defects and shrinkage porosity are reduced thus parts made from centrifugal casting exhibit denser, closer grained structure with improved physical qualities such as tensile strength, yield strength, elongation and uniformity.
