  • Method for moulding light alloy cast parts, in particular cylinder blocks
    Patent number: 7270168
    Abstract: The invention concerns a method for casting a part made of metal alloy such as an aluminum alloy comprising the following steps: forming a core (N, PNC) having at least one shaft (PC) designed to form in the part a cylinder and at least one cavity (P) designed to form in the part a support and/or retaining zone for a working member, and at least a cooling unit (RE) proximate to the cavity; positioning the core in a metal mould cavity, and feeding the mould lined with its liquid alloy core by gravity. The invention is particularly useful for casting internal engine cylinder blocks with aluminum cylinders with improved geometrical and mechanical properties of the crankshaft bearing zones.

  • Process of fabricating castings provided with inserts, with improved component/inset mechanical cohesion, and an insert usable in the process
    Patent number: 6964292
    Abstract: A process of fabricating a light alloy casting, such as an aluminum alloy casting, including at least one metal insert includes applying a coating of lampblack to a face of the insert intended to be in contact with the alloy of the component and casting the component with the molten alloy in a mold cavity in which the insert is positioned. Applications include fabricating engine blocks with integrally cast liners made of cast iron.
