Hubei JYS Advanced Wear Resistant Material Technology Co.;Ltd have had imported the newest casting technology to manufacture crusher wear parts. Our foundry always insist on improving casting technology,right now, we have had success to use those casting technology: Water Glass Casting,V Method Casting and Lost Foam Casting.
Water glass casting (which also called sodium silicate casting) is a technology of Russian origin. This technology is mostly used for steel and stainless steel components. By using this technique more complex designs can be made compared to the sand casting technique. it is for big size products more interesting, compared to silica sol castings, however less precise in dimensions.Water glass (sodium silicate) is used to cure the ceramic layers. This substance is added to the crusher wear parts.It is then placed in a bath with a water chloride solution. The water glass reacts to this solution in the bath, thereby curing the layer. This layering process is repeated a number of times until the layer is sufficiently thick enough for pouring. If necessary, a smoother casting surface can be achieved by using the first ceramic layers as it is used in the silica sol technique. Only it will take longer to make the shell.
Compare to traditional sand casting, V method casting not use any adhesives.It uses plastic film sealed sandbox, by vacuum suction system out of the type of air, inside and outside the mold pressure difference, so that dry sand dense, the formation of the required cavity, the core, the box, pouring vacuum casting solidification, Remove the negative pressure, sand and then collapsed to obtain castings.
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold.
