Wholesale Steel Investment Casting Manufacturer - Grey Iron Casting Machinery Part by Investment Casting – RMC Foundry Detail:

China OEM custom gray iron castings produced by lost wax precision investment casting process.

What Are The Investment Castings Used For?
Investment castings are widely used in pumps and valves, automobile, trucks, hydraulics, forklift trucks and many other industries. Because of their exceptional casting tolerance and exellent finish, the lost wax castings are used more and more. Especially, the stainless steel investment castings play a vital important role in the shipbuilding and boats because they have strong anti-rust performance.

Casting Tolerance Could Reached by Investment Casting:
According to the different binder materials used for making the shell, the investment casting could be divided into silica sol casting and water glass casting. The silica sol investment casting process have better Dimensional Casting Tolerances (DCT) and Geometrical Casting Tolerances (GCT) than water glass process. However, even by same casting process, the Tolerance Grade will be different from each cast alloy due to their various castability. Our foundry would like to talk with you if you have special request on the required tolerances. Here in the following are the general tolerances grade we could reach both by silica sol casting and water glass casting processes separately:
✔ DCT Grade by Silica Sol Lost Wax Casting: DCTG4 ~ DCTG6
✔ DCT Grade by Water Glass Lost Wax Casting: DCTG5 ~ DCTG9
✔ GCT Grade by Silica Sol Lost Wax Casting: GCTG3 ~ GCTG5
✔ GCT Grade by Water Glass Lost Wax Casting: GCTG3 ~ GCTG5

Gray Iron Applications
The following is the common application for each degree of grey cast iron for your reference.
HT100 (GG10, EN-GJL-100):
For small loads, the friction and wear no special requirements for important castings, such as protective cover, cover, oil pan, hand wheels, frame, floor, hammer, small handle, etc.
HT150 (GG15, EN-GJL-150):
Under moderate load of castings, such as the base, frame, box, knife, bed, bearing seat, table, wheels, cover, pump, valve, pipe, flywheel, motor blocks and other
HT200 (GG20, EN-GJL-200):
Requirements withstand greater load and a certain degree of tightness or corrosion resistance of the more important castings such as cylinder, gear, base, flywheels, bed, cylinder block, cylinder liner, piston, gear box, brake wheel, coupling Plate, medium pressure valve, etc.
HT300 (GG30, EN-GJL-300):
Under high load, wear and high air tightness important castings, such as heavy machine tools, shears, presses, automatic lathe bed, frame, frame, high-pressure hydraulic parts, piston rings, force larger gear, Cams, bushings, large engine crankshaft, cylinder block, cylinder liner, cylinder head, etc.
