Shell moulding foundry

Shell moulding casting (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.

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.

With the molten metal fills the shell, through a casting system with a feed channel specially designed for each rough casting to be produced, all kinds of fusion.

The advantages of fusion with shell moulding method compared to a traditional sand casting are:

  1. the possibility of obtaining castings with complex geometry, thin and low dimensional tolerances, so as to minimize the processing allowance
  2. A surface with low roughness, very useful feature on the pieces with areas that do not provide for finish machining.
  3. The shell permeability allowing the reduction and/or the Elimination of non-conforming castings for presence of gas bubbles.
  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.
  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.

The materials cast by means of the shell molding foundry are as follows:

  1. grey cast iron
  2. spheroidal cast iron
  3. vermicular (compacted) graphite iron
  4. Ni-resist cast iron
  5. Ni-hard cast iron
  6. Cr-hard cast iron
  7. stainless steels


Shell moulding foundry production

The production of Foundry Department Shall-Moulding is for use in the manufacture of components for the following sectors: automotive, marine, aviation and racing, as well as textile industry and mechanical.


  • valve guides for naval 4T engines
  • tappet for airplane 4T engines
  • crankshaft for piston air compressors


  • distributor for hydraulic system


  • cylinder for diesel engines
  • cylinder piston air compressor

What can we do for you?

Fonderia di Lonato can produce cast-iron and steel castings on the customer’s specific design, providing a product that meets the mandatory requirements specified in the contract.

Our systems allow for the production of castings from 0,2 to 40 kg , and, if required by the customer, perform heat treatment, cutting and roughing machining on them.
