MOULD WITH GASKET AND MOULDING METHOD FOR COMPENSATING CURING SHRINKAGE

摘要

A compensating mould comprises a first, obverse face-forming part (11) and a second, reverse face-forming part (10), said first and second parts being separated by a compensating gasket (12) positioned around the edge of the mould characterised by the presence of a nett edge gasket (16) comprising an elongate resilient gasket positioned between the first and second mould parts (10, 11) such that the nett edge gasket (16) is in intimate contact with each of the first and second parts of the mould and forms a barrier to the flow of flowable curable composition (14) contained within the mould around at least a part of the edge of the mould. The use of the nett edge gasket allows the wastage of material in forming a moulding flash and the labour of trimming the flash away from the article to be avoided.
