Abstract (en)
A method of supporting a soluble insert structure within a mould die ceramic injection moulding (CIM) process, the method comprising the steps of: forming at least one chaplet that supports the soluble insert structure within the die, the chaplet being formed of a ceramic material that has substantially similar physicochemical properties to the main internal core structure; and positioning the chaplet to contact the soluble insert structure to the die, the soluble insert being spaced away from an edge of the mould die. The chaplet may comprise a refractory material or a combination of refractory materials.
