Abstract: A lining plate for lining a mould chamber in a sand molding machine. A base unit, is equipped with functional openings for injection of particle material, an air exhaust and fasteners. A layer of a synthetic resin material which is cast integrally onto the base unit faces the abrasive areas of said mould chamber. A method of manufacturing a lining plate comprising a base unit equipped with functional openings for injection of particle material, and/or air exhaust openings and fasteners. A method of refurbishing a lining plate in a sand molding machine comprising a base unit equipped with functional openings for injection of particle material, air exhaust openings and fasteners.

Abstract: The present invention relates to a lining plate (10) for lining a mould chamber in a sand moulding machine, said lining plate comprising a base unit (11), whereby said base plate may be equipped with functional openings for injection of particle material (16) and/or air exhaust (7) as well as fastening means for releasable fastening of the plate to the mould machine. A layer (12) of a synthetic resin material is adhered to said base unit (11). The layer (12) is intended to face the abrasive areas of said mould chamber, thereby forming part of the inner surface of the mould chamber. The invention further relates to a method of manufacturing a lining plate (10) for lining a mould chamber in a sand moulding machine comprising a base unit (11), said base unit (11) being equipped with functional openings for injection of particle material (16) and/or air exhaust openings (7) as well as fastening means for reliable fastening to the mould machine.
