Technical ceramics cover a broad spectrum of activities and interests; each user has a unique balance of requirements.   Generic benefits of pressure-casting on synthetic moulds over traditional casting on plaster can include:   Greater precision and reproducibility Improved mould life Elimination of dimensional changes due to ageing of plaster moulds Elimination of dimensional changes due to changeover of plaster moulds Reduced factory area for casting Improved purity Improved manufacturing:     no need to manufacture plaster moulds   reduced finishing   increased productivity   improved yields   opportunity for mechanisation   As well as fabricating the moulds, PCL develops and manufactures its own microporous polymer technology. This brings about the possibility of manipulating the functional properties of its moulds to match specific applications.   Microporous polymer moulds are essentially self-supporting filters. As well as pressure-casting tools, our moulds may, for example, find application in capillary casting and electrophoretic forming (from water-based slips)
