A casting mold assembly comprises at least one sleeve (1) wherein said sleeve (1) is in contact with a consumable material (2) prior to pouring. During pouring the consumable material (2) combusts or vaporizes. As a result, a gap containing air or other gases is formed which partially or totally surrounds the sleeve (1). The invention also relates to the preparation of such sleeves (1) and their use in the casting of metal parts.
