Shell moulding foundry<\/h1>\n

Shell moulding casting<\/strong> (Crowning process) plans to pour the molten metal, within a sand shell hot format, which can contain one or more cores, to get a casting with minimal dimensional tolerance and low surface roughness.<\/p>\n

This method of production involves preparation, through forming machines, shells, sand treated with thermosetting resins, with variable thickness. Inside the shells are inserted some “cores” to get a rough cast with geometry and dimensions very similar to the finished piece.<\/p>\n

With the molten metal fills the shell, through a casting system with a feed channel specially designed for each rough casting to be produced,\u00a0all kinds of fusion.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/3″]

\u00a0<\/span><\/p>\n<\/div>[\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]The advantages of fusion with shell moulding method<\/strong> compared to a traditional sand casting are:<\/p>\n

    \n
  1. the possibility of obtaining castings with complex geometry, thin and low dimensional tolerances, so as to minimize the processing allowance<\/li>\n
  2. A surface with low roughness, very useful feature on the pieces with areas that do not provide for finish machining.<\/li>\n
  3. The shell permeability allowing the reduction and\/or the Elimination of non-conforming castings for presence of gas bubbles.<\/li>\n
  4. Absence of any remaining moisture (because it is a hot forming) resulting in a reduction of blowholes and hard spots (cementite) in the thin material especially in spheroidal cast iron.<\/li>\n
  5. possibility of casting complex parts in alloy due to the availability of sands with different composition and grain size, which allows us to control the process of cooling and then, to minimize the possibility of having scraps for micro retreats.<\/li>\n<\/ol>\n

    The materials cast by means of the shell molding foundry <\/strong>are as follows:<\/p>\n

      \n
    1. grey cast iron<\/li>\n
    2. spheroidal cast iron<\/li>\n
    3. vermicular (compacted) graphite iron<\/li>\n
    4. Ni-resist cast iron<\/li>\n
    5. Ni-hard cast iron<\/li>\n
    6. Cr-hard cast iron<\/li>\n
    7. stainless steels<\/li>\n<\/ol>\n
