MOULDING ELEMENT FOR A TYRE MOULD COMPRISING A POROUS AREA

摘要

The invention concerns a moulding element for a tyre mould produced from a metal powder melted layer by layer. The moulding element (1) comprises a first surface (5) for moulding all or part of a tread of the tyre and a second surface (7) opposite the first surface and intended to be in contact with another part of the mould. The thickness (E) of the moulding element is between 1 and 6 millimetres. The moulding element has an overall density greater than or equal to 98%. The moulding element further comprises at least a first porous area (9) extending in the thickness of this moulding element, this first porous area comprising a plurality of pores allowing air to pass between the first surface of the moulding element and the second surface of same.
