Molten Metal Filters

Molten Metal Filters also called, as ceramic filters have become an indispensable part of the casting technology in the present day contest. These filters find optimum use of aluminum casting, gray iron casting and nodular casting with a temperature of withstanding capacity of 1480 C. Also greater emphasis is being made by designers to reduce the casting weight which is becoming a global demand. To achieve this wall thickness of the casting has to be reduced.
Further more the high cutting speeds also require increasingly higher casting quality.
This means that the customer requirements in terms of low weight, resulting in cost savings with defect free castings are becoming ever demanding. The thinner wall castings are more sensitive compared to thick wall castings causing serious damage with subjected to high stress. Improving the casting quality is by use of clean melt. Any non-metallic inclusion represents weakling of the cross section of the casting
