What material is the material used in precision casting? What is the raw material?
The common method of precision casting is casting, also known as the lost wax casting, with paraffin as it looks, with quartz sand shell, the shell after hardening, melted paraffin after the formation of the cavity, drying after pouring liquid metal, precision casting solidification will get complicated shape and smooth surface.Precision casting materials used, the most common cast steel, cast iron and bronze, they used the material and general steel and iron and copper raw materials are the same, the key is the special casting method, high surface precision castings.
Precision casting is a general term for precise casting process obtained by precise molding. It includes investment casting, ceramic mould casting, metal mould casting, pressure casting and EPC casting.Among the more common is the investment casting: choose appropriate revestment materials manufacturing mold; casting was repeated in the dip coating and sanding process, hardening type shell and drying; then the internal mold melt, get cavity; roasting shell to obtain sufficient strength, burn casting mould materials. The residual metal; casting materials needed; shell after cleaning, so as to achieve high precision of finished products. Heat treatment and cold processing, as required by the product.Precision casting is a casting method that can be applied to any material.
Precision casting generally rely on the specific material processing for survival is to do need to provide the standard material of many kinds of stainless steel 316 316L 304303 carbon steel and alloy steel etc. and can precision casting. Specific mold is to see how you cast blank is required, divided into water glass casting, silicon sol casting, can also use compound die. Copper and aluminum, for example, are usually sand bonded and gravity cast or die cast.
