Cearmic foam filter for Sand casting and Investment casting
Description
These ceramic foam filters are designed for mould-casting metal.The reticular shape of the foam filter provides a thorough and deep filtration to remove impurities in molten metal stream.Ceramic foam filters have excellent ability to resist high thermal shock while maintaining efficient filtration. They are widely used in sand, investment, shell and permanent molds for both ferrous and non-ferrous alloy filtration operations.Thanks to the mechanism of creation of the "filter cake" on the inlet filter side and thanks to depth filtration inside the ceramic matrix, these ceramic foam filters are an effective instrument to reach metallurgical purity of molten metal during the process of casting. The filters also calm mould filling, thus preventing creation of undesirable defects in the casting.

Physical properties and Applications
How To Choose Porosity Of Filter:
• The higher porosity, the better filtration. But too high porosity leads to low speed rate of metal. This is especially important for SG iron.Usually our recommendation are as below:
• 10ppi-for ductile iron, big grey iron, steel casting.
• 20ppi-for grey iron, malleable cast-iron,non ferrous alloy casting.
• 30ppi-for grey and malleable cast-iron, non ferrous alloy casting.
How To Set Filter:
The ceramic foam filter can be used in the filtration chamber of a gating system as well as for direct
pouring on the filter.
Filter is usually set above or below the sprue, runner, in pouring cup.
Packing Details :
Inside packing: Filters are put in small box and Layered packaging. There is cardboard between each layer.
Outside packing: Cartons&Pallets. Three layer corrugated cartons and export special pallets .
The mark on cartons can be designed according to the customer's request.
Delievery & Delievery Time : 10-15days after signed the contract
