Claims11
A method of forming parts, each part formed from a ceramic moldable material and having a central bore, the diameter of the central bore being relatively small with respect to the cross-section of the part, the part formed in a mold mounted on a suitable support structure, the method comprising:
- mounting a relatively thin flexible member on the support structure under tension;
- mounting a mold on the support structure with the flexible member extending therethrough, said mold having a body cavity for receiving the ceramic moldable material, said body cavity defining a body part having a cross-section substantially larger than the cross-section of the then flexible member passing therethrough;
- enclosing the mold in a perforated cage provided on the support structure, said cage enclosing and supporting the mold;
- inserting the ceramic moldable material into the mold to surround the tensioned flexible member along the length of the member within the mold;
- and
- removing the flexible member from the formed part.
