Ceramic pouring and filtering cups Riser in casting are used for investment casting technology. Riser in casting are made of high-quality ceramic material and pressed at high pressure. They are fit for casting ferrous as well as non-ferrous metals, withstand the most strenuous conditions within superalloys casting for aircraft industry.<\/p>\n

Riser in casting provide these benefits<\/strong>
\nreduced castings contamination by ceramics of a ceramic shell
\nsignificantly reduced wax consumption from gating system production
\nreinforced shells enabling handling within the production cycles
\npossibility to accommodate ceramic filters of standard dimensions
\nCeramic pouring cups are characterized by these properties:
\nhigh mechanical (manipulation) resistance and dimensional accuracy
\nsmooth working surface as a protection of metal erosion
\nhigh chemical purity of used raw matequirements.<\/p>\n

\nStrong corrosion resistance, high geometric precision, smooth casting surface, long service life, low maintenance cost, no pollution to molten metal, is the best choice for hot top casting.
\nRiser in casting meets the technical needs of aluminum alloy precision casting products such as aviation, transportation, and electronic products that produce high added value and high technical performance requirements.<\/p>\n

Riser in casting advantages<\/strong>
\nIt has good wetness, smooth glaze, high geometric processing precision and low maintenance cost.
\nNo delamination and peeling phenomenon, effectively reducing the pollution of aluminum liquid, and achieving non-polluting fine aluminum casting;
\nResistant to erosion, good thermal shock resistance, improved corrosion resistance to molten metal;
\nIt is better used with boron nitride (BN) coatings and has a normal life of 450-800 castings to save energy and reduce consumption.<\/p>\n

Aluminium Casting accessories instructions<\/strong>
\nSelect the hot-top casting equipment platform mounting accessories of the corresponding specifications;
\nThe split plate, Ceramic pouring and filtering cup, adapter plate, splitter groove, graphite ring are mounted on the upper side of the platform, the casing and the adapter plate, and the graphite ring is installed on the inner side of the crystallizer to ensure cleanness, no damage, no gap. The side and bottom are preferably sealed with ceramic fiber paper or ceramic fiber blanket to help keep the heat treatment;
\nAfter the whole hot-top casting platform is installed, evenly preheat the installed equipment platform to 260-350 \u00b0C. It can be electrically or gas-baked. There should be no open flame contact with the product lining, otherwise the crack damage will occur. The user undertakes to remove the adsorbed crystal water and use it safely and efficiently.<\/p>\n
