Ceramic Foam Filters

The most effective way of improving a foundry's yield is by using an efficient filtration system. Ceramic Foam Filters are the most effective filtering system available, and are used widely to reduce scrap and improve yield. Apart from capturing unwanted inclusions, they also reduce turbulent flow. The simple running systems developed with Ceramic Foam Filters provide extra castings, at times within a given mould box, which results in an improved box yield. The proper use of Ceramic Foam Filters in the runner system helps in reducing the length of the runner and gates, hence long runners and in-gates need not act as slag traps. The shorter runners and in-gates, in turn, help in increasing the yield significantly.

6) Strength (hot or cold) is critical. The filters should be strong enough to withstand physical stresses during shipping and
   handling. They should also remain intact when the molten metal passes through them.

3) Flow Rate must be high and consistent. Huge variations in flow rate could lead to mould-fill problems.
4) This demands larger filters, which in-turn, increases cost and decreases yield.
5) Dimensional Accuracy is crucial. The filters should fit into the print cavity precisely.

1) Filtration Efficiency is important. The slag and dross have to be removed from the molten metal to prevent them from
   entering the mould cavity.
2) Metal Capacity must be adequate and consistent. The capacity must not vary from filter to filter, which could lead to
   premature blockage.

Features that make Ceramic Foam Filters effective in Cast Iron Filtration:

Non-metallic inclusions (flaws caused by impurities) in a casting are one of the most widespread causes of casting defects. They adversely affect surface finish; mechanical properties, machining characteristics and pressure tightness - and can lead to a casting being scrapped. Patronage has led the industry in removing impurities, reducing turbulence and providing rapid and consistent metal flow through its supplied filtration systems.
These filtration systems remove inclusions, reduce turbulence and provide rapid and consistent flow. We are the growing supplier of foundry filters in the India, with the widest choice of foam and cellular filters for aluminum, copper, iron and steel casting applications.
