Why Extruded Filter Is Gaining Attention In Non-Ferrous Foundries

Filtration of the liquid metal is a common part of the moulding process. Most industries in western countries are using the filters in large numbers and more frequently to come up with some suitable cast moulds. These are found in the junction of the metal flow and the metal cast mould. By using the ceramic foam filter, lots of advantages are acquired by the industries in terms of quick turnover, better quality cast moulds and improved output for the company. Many companies are nowadays using the filtration with foam filters, when it is related with the ferrous deposits. But, zirconia ceramic foam filter is also being increasingly sought for the industries, which are using cast moulds in cases other than iron. Usually for aluminium, steel, alloys and few non-ferrous alloys, the zirconia filter appears to be more effective than the ceramic ones.

• Removal of scrap and impurities better with uniform porous filters

In foundries, which do not cast iron, but other kinds of metals, extruded filter process is the preferred mode of removing the scrap and impurities. In this kind of filter, there are pores of uniform size and the shape is somewhat like a beehive. Plenty of pores are there, which helps in double filtration and give the best results for non-ferrous liquid metal. Since the pores are larger in size, they allow quick flow of metal through different directions, thereby even filtering liquid materials which may remain in the metal cast. Therefore, extruded forms of filter could be a better options, which is very much effective for non-ferrous substances and the materials with which these filters are designed, actually are quite strong and resistant to the heat and corrosion. So, zirconia filter has become a favoured substance in high temperature conditions.

• Wide acceptance of the quality filters for liquid metal

Furthermore, filtration is seen nowadays as an essential element of the casting industry. Most of the companies are changing their filters to add zirconia ceramic foam filter as the need of such materials is seen to be urgent. The material of zirconia is supposed to be quite resistant to heat, while the filtration is also more efficient. It is therefore important to understand the implications of using the zirconia filter in the non-ferrous casting process, where it offers some advantages. When this filter is designed in the extruded form, rather than the foam type, it filters in a better way, thereby bringing up better quality of metal cast moulds in the industries dealing with the production of such types of forms.

• Filters made from zirconia add value to the designs and form

Moreover, zirconia ceramic foam filter is a very good way to improve the efficiency of the metals being moulded and casted. This is supposed to add value to the company’s production as there is very little rejection, improved filtration, durability of the filter and better forms of designs. Overall, for the non-ferrous foundries, it is advantageous to use the extruded filter with materials like zirconia, which are more tolerant to heat and corrosive effects of the liquid metals.
