Metallic Hammer mold (dies) is made of the grey iron. The inner chamber is milling by the CNC machine.
Using method: 1. first, same like the grinding ball metal mold, using acetylene to heat the chamber to form a layer so that it's easier to separate the hammer and mold.
2. first time using, the metal mold should be heated to 200-300 degrees. You can use heat treatment machine to heat or pour the half molten iron into the mold and let the iron's temperature heat the mold.
3. Need to prepare the precoated sand mold to put into the hole for supporting. (The making method see the video below)
4. Using the pattern to form the sand in the middle of the mold(die), make a hole for pouring.
Details see the video below.
