Application ceramic foam filters on vertically parted moulding lines

摘要

The paper describes the principles of applying filters to vertically parted moulds such as Disamatics. Key differences between horizontally and vertically parted moulds are outlined. A simple system to categorise Disamatic mould types into 3 categories is described and the effect of differing ingate positions on filtration application practice are outlined. The calculation technique for determining the minimum or controlling gating system cross-sectional area for vertically parted moulds is described. The optimum location of the foam filter in the mould is explained. Filter print designs for Disamatics are given, their role in securing the filter in the mould along with filter handling techniques are described.
