Abstract
A method of removing a core from an object formed by injection moulding starting from a compound comprising a metallic and/or ceramic powder material. The outer contour of the object is formed against an external tool arranged in an injection moulding tool and at least the inner contour of an inner cavity is formed against a core (11, 21) provided in the injection moulding tool. The core consists at least partly of a leachable core material which is removed, wholly or partially, from the injection-moulded object by directing at least one jet of a leaching liquid against the leachable core material by means of one or more spray nozzles. The leachable core material is dissolved and flushed away and said nozzle is inserted successively into the inner cavity as the leachable core material is being dissolved and flushed away. The core is then removed in its entirety and the inner cavity exposed before said object is sintered and consolidated into the desired density by means of methods which are accepted within the powdermetallurgical and ceramic industries.
