Investment casting is the process of forming metal or metal alloy products (also called castings) by solidifying molten metal. Precision casting is an important method for producing high-quality precision casting metal products in various industries. Castings usually contain unwanted materials called “inclusions.” The generation of inclusions can be attributed to the slag or scum material […]

AdTech provides a high-efficiency ceramic foam material for filtering molten metal, especially molten aluminum. The ceramic foam material is characterized by having a three-dimensional network structure with a plurality of interconnected voids surrounded by the net of the ceramic material with ceramic fibers. The air permeability of the filter is 400 to 8000×10 -7 cm […]

Asian foundry filter agent has been authorized by China’s manufacturers to sell foam ceramic filters to local aluminum plants. The purification purpose of ceramic foam filter in aluminum foundry is to remove alumina slag and hydrogen from aluminum melt to improve the process and mechanical properties of aluminum materials or products. In the process of […]

The quality of aluminum melt is very important, and it greatly affects the subsequent processing performance and the quality of the final product. Therefore, all countries in the world wish the purification of aluminum melt very seriously. Ceramic foam filtering technology has been used to remove inclusions in molten aluminum for more than 30 years. […]

The ceramic foam filter has a network pore structure, has a certain strength, can withstand the pressure difference of the metal liquid level and the impact of the metal flow, but it is brittle and fragile. Because this material has a precise structure, uniform quality, and has a great surface area, so the ceramic filter […]

Using a 20 PPI ceramic foam filter to filter and purify A356 alloy, by observing the changes in the tensile properties and elongation of the alloy before and after purification, the following conclusions can be drawn: The filtration and purification of the 20ppi ceramic foam filter can improve the tensile strength and elongation of A356 […]

A lot of practice shows that the use of foam ceramic filter material can remove inclusions, improve the structure of castings, improve the mechanical properties and pass rate of castings, improve the processing performance of castings and reduce machining costs. Foam ceramics have a good filtering effect and no pollution to the alloy. However, if […]

The liquid metal filter was developed in the 1970s. The liquid metal purification technology was first applied to aluminum alloys. Because the melting point of aluminum alloys is low, the density of alloys and oxides are close, and inclusions are difficult to float. Inclusions are the most common casting defect. In casting production, many process […]

After using the ceramic foam filter for metal casting, the rectifying effect of the ceramic foam filter can be fully demonstrated. The molten metal flowing through the ceramic foam filter has a trickle and converges into the mainstream of laminar flow. The laminar flow state of molten metal fills smoothly, avoiding the secondary oxidation and […]

Aluminum liquid filtration generally uses foam ceramic filter filtration. When the aluminum liquid passes through the tortuous and interconnected pores in the foam ceramic, the internal debris is deposited on the wall of the pore under the action of fluid power, inertia, interception, collision, and adsorption. So that the clean aluminum liquid enters the casting […]
