The process-safe feeding of nonferrous metals can be supported by the targeted use of insulating riser sleeves. The main properties and advantages of this feeding technology can be summarized as follows:
The self-centering inner contour ensures rapid equipping of pattern plates with risers in synchronization with the molding plant. Tilting of the riser on the pin – and the subsequent crooked ram-up – is effectively prevented. The ergonomic external contour of the POINT-Riser® supports the flowability of the mold sand, reducing the risk of uneven compaction of the molding material due to, for example, compaction shadows below the risers.
