Investment Casting Sand for Casting Precision Parts of Mobile or Plane
What is investment casting?
Investment casting, also called lost-wax casting, makes parts from molten metal, usually stainless-steel alloys, brass, aluminum, and carbon steel. The first step in the process is to build a wax version of the final product. This can be done in one of three ways:
1. Form a gelatin mold around a solid, 3D model of the final product.
2. Create a metal mold of the final product, and then fill it with hot wax.
3. Carve and machine a replica of the product out of wax.
To cast several parts at once, several wax patterns can be assembled into a tree with wax runners and sprues carefully connecting them. The “tree” is then repeatedly dipped in a ceramic slurry that hardens when it dries. After receiving several layers of ceramic that are allowed to harden, the tree and its patterns are heated to remove the wax. The wax in the sprues and gates also flows out of the tree and forms tubes and pipelines for molten metal to follow and completely fill the mold.
Molten metal is poured into the now-empty mold and left to solidify. The ceramic mold, the investment, is destroyed to remove the part(s).
Investment Casting Sand Introduction
Investment Casting Sand usually refers to Mullite, as aluminum silicate refractory, is generally used in stainless steel precision casting process. The higher the aluminum content and the lower the iron content in the mullite, the better the quality of mullite products. Mullite is made of kaolin by high temperature sintering.
Mullite sand generally has 8-16 mesh, 16-30 mesh, 30-60 mesh, 60-80 mesh, 80-120 mesh; mullite powder generally has 200 mesh, 300 mesh, etc.
The usual components of Mullite sand:46%≥Al2O3≥42%,53%≥SiO2≥51%,1.2≤Fe2O31≤1.5%,Na2O+K2O≤0.3%,CaO+MgO2≤0.6%,TiO2≤0.1%.
Advantages: the casting of pouring is easy to be shelled, not deformed, not easy to shrink, with good finish and high ratio of finished products.
