Why does Ceramic sand replace silica sand? Ceramic sand is more and more acceptable and popular in the Lost Foam foundry to replace silica sand. Silica sand (quartz sand) is easy to get at a low cost. But its two major drawbacks. The first one is high expansion coefficient lead to low casting accuracy. The …
Foundry Ceramic sand is a casting sand material based on aluminum oxide. It is spherical casting sand made by melting calcined bauxite. After high-temperature melting, ceramic sand still maintains a high density and specific gravity, with a specific gravity of 3.4g/cm3 for ceramic sand with a 70-72% alumina content. After making spherical particles, due to …
How the foundry ceramic sand helps the foundry plant Foundry ceramic sand is a kind of aluminum oxide-based foundry beads. It is made from bauxite by a fusing & blowing process. The foundry beads are of solid ball shape. That led to some specific extraordinary features for the foundry production. It can help foundry plants …

Ceramic foundry sand for core making The hydraulic main control valve, a component of an excavator, is a complex hydraulic component. It mainly serves to transmit the pressure oil discharged by the pump to different executing components according to specific instructions. In this way, the excavator can complete various actions. The material of the …
Spherical Casting Sand Ceramic sand Spherical Casting Sand Ceramic sand has the unique shape of microspheres. In fact, it is an electrofused bauxite sphere. The main chemical content is aluminum oxide. So it has similar thermal features to corundum such as high refractoriness, goods chemical stability, etc. The most important property of Casting Ceramic sand …
Ceramic sand 100-200mesh for 3D printing Ceramic sand 100-200mesh for 3D printing works goods in precise castings. For some complicated mold in the foundry, the cost of molding is very high. 3D printing is a good way to solve the problem. And It’s flexible for adjusting the mold shape. Ceramic sand 100-200 mesh works for …
Ceramic sand AFS35 for mold casting In traditional precision casting, quartz sand or corundum sand is generally used as the base material for shell making. The shell-making process of this casting method is complex, the recycling rate is low, and the efficiency is not high. The precision casting process of ceramic sand has improved …
Choose proper fused ceramic sand for casting Fused ceramic sand is an alumina-based ceramic bead for foundry. It obtains extraordinary characteristics such as high thermal resistance, low angularity, high mechanical strength, etc. As synthetic foundry sand from calcined bauxite material, fused ceramic sand quality is stable from a strict production and quality control system. However, …
Ceramic sand for shot blasting Ceramic sand is a kind of spherical sand made of calcined bauxite by fusing process and blowing. Spherical sand is blasting media for shot peening. It has the advantages of no damage to the workpiece and no scratches. Ceramic sand is usually for casting molding sand and raw sand. It …
Ceramic sand for Nonferrous metal foundry Ceramic sand for foundry is always used for iron casting and steel casting. But the ceramic sand works perfectly for nonferrous metals to decrease the total foundry cost. Recently, a lot of nonferrous metal foundries adopt ceramic sand for castings such as Aluminum alloy, Copper alloy, and Zinc alloy. …
