METHOD OF MAKING ACRYLIC MOULDED ARTICLES

摘要

A mould for moulding, for example, an acrylic worktop for a kitchen comprises two mould halves which include a mould base (2) and mould top (4) arranged to co-operate with one another to define a mould cavity into which polymerisable material may be input. The surface of mould halves which contacts the polymerisable material comprises a composite material (6) which comprises extruded polypropylene sheet with a polyester fabric laminated to one side. The sheet is supported by means of supports (8) which are retained in position by a layer (10) of GRP. After input of the polymerisable material into the mould cavity, it is allowed to cure to define a product from which the mould base and top may be removed. The product may then be placed in an oven at about 120 DEG C to fully cure it. In another embodiment described, a mould comprises two mould halves made by thermoforming or vacuum forming polypropylene sheet.
