Ceramic foundry sand with RCS advantages For some precise steel casting about 10-100 kgs ceramic foundry sand with RCS technology get many advantages. Especially compared with Investment casting, it save cost and make the casting process more efficiently. 1. High casting quality. • Good surface quality: The ceramic foundry beads are round and spherical, with …
Casting Ceramic Sand Properties and Usage Casting Ceramic sand, also known as fused ceramsite sand, is a high-quality substitute for silica sand. It is a non-silica-based artificial sand. It is suitable for various casting methods such as V-method, VRH, lost foam casting, investment casting, resin-coated sand, no-bake sand, etc. Casting ceramic sand is suitable for …
What is the angular coefficient of Ceramic foundry sand? Ceramic foundry sand is spherical casting sand that can be used as surface sand and molding sand. Many excellent characteristics of ceramic sand come from the morphology of particles. The spherical shape is beneficial for increasing the fluidity and collapsibility of casting sand. The angular coefficient …

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 leads 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 …
