Claim:
1. A method of manufacturing a lining for a mould chamber in a sand moulding machine, which lining comprises a metallic base plate and a synthetic resin wear layer, comprising the steps of: providing a casting tool, placing the metallic base plate, which has functional openings therethrough, into the casting tool, introducing a liquid synthetic resin into the casting tool onto the base plate such that the resin forms said wear layer on the metallic base plate, curing the synthetic resin wear layer on the metallic base plate until it hardens and is integral with the metallic base plate, and machining the cured synthetic resin wear layer to provide functional openings therein corresponding with the said functional openings in the metallic base plate and to provide final surface quality and tolerances for thickness and parallelism of the complete lining.
