Main Features

Super quality method and equipment allow us to produce Ni-Hard, Hi-Chrome Iron castings with Brinell hardness over 650 for shovels and wear plates. Other parts like mixing arms are made from alloy steel castings.

High precision ratio of metal composition; accurate designed screw hole position, lost foam casting technique, high wear resistance. Customized design is welcomed!

 

1. Making polyfoam gasification mold
2. Polyfoam gasification, combine the molds then dry
3. Spraying fireproof paint on the surface of polyfoam mold, then dry again.
4. Put the special sand box on the three-dimensional vibration compaction stage
5. Filled the sand box with dry sand, then strike-off
6. Putting the dry polyfoam mold on the sand, then fill different sand according to the technological requirements
7. Strike off the sand box after the process of vibration compaction
8. Covering the sand box with plastic sheet, put down the pouring cup, connect the negative-pressure system. Then pour steel liquid, the polyfoam disappears, the steel liquid takes place of the polyfoam.
9. After casting condensation, release the vacuum, then take out of the castings
