Hydraulic brake rotor for diesel locomotive

which has the features of distinct difference in wall thickness

requires the whole casting and high dimension precision

so it is very difficult to produce by investment casting.The technological process in investment casting hydraulic brake rotor was described including structure design

wax-pattern making

mold making and dewaxing

melting as well as pouring.The qualified hydraulic brake rotor was successfully produced by adopting combined supporter with the same materials for castings to prevent collapse and using low point wax as well as assembling welding wax-pattern

and so on.
