Spun cast sleeves typically have much finer ASTM type D flakes throughout the bulk of the tube wall, with a small amount of type C or A flakes on the inside surface of the pipe.Pit cast iron parts typically has large ASTM type C flakes (ASTM, 1998)Type D graphite flakes in the spun cast grey iron tubes produce less initial plastic deformation than the larger type C flakes in the pit cast iron tube.
Our Gray Iron compressor parts 120 to 350 mm in diameter and 300 to 500 mm long are spun-cast on spindle machines. These centrifugal cast machines can be operated at anywhere from 540 to 1260 rpm.
Outstanding Features:
1.We use Spetrometer to control the chemlcal elements;
2.We check the matrix with our mlcroscope;
3.We can do fully machining on the sleeve parts.
4.We adopt Centrifugal Cast process with higher efficiency to shortening the process time;
5.Production Process: centrifugal cast process + machining process
7.We can make the cast sleeves as per customer design.
8.Diameter: 50mm - 500mm; Length: less than 400mm.
