As a casting sand in the Cold-box Core Making process, Ceramic sand has many extraordinary advantages such as high refractoriness, easy to shake off, recycle used, etc. The use of Ceramic sand can avoid many defects in the casting process for a large range of different castings. In the meantime, it can save cost as a whole for each ton of castings.
The following table shows excellent effect with different application for castings by adopting ceramic sand:
Casting Type | Casting Material | The application of Ceramic sand | The Effect by using Ceramic Sand |
Cylinder Head | Gray cast iron | Water jacket shell core | Less damage to the core, fewer veins on the casting, easy to clean sand |
Cylinder Head | Gray cast iron | Shell core(Rein No-bake shell molding) | Less damage to the core, fewer veins on the casting, easy to clean sand |
Pump | Copper alloy | Alkaline phenolic resin core making | Vein lines and pore defects on castings are significantly reduced |
Hydraulic valve, Cylinder block | Gray cast iron /Nodular cast iron | Shell core | Less damage to the core and fewer pore defects |
Hydraulic valve | Gray cast iron | Shell core | Less damage to the core, fewer veins on the casting, easy to clean sand |
Cylinder Head | Copper alloy | Shell core | Less damage to the core, fewer veins on the casting, easy to clean sand |
Hollow camshaft | Nodular cast iron | Surface sand | The shell core is less damaged, easy to clean sand, and the surface quality of the inner hole is improved |
Cylinder block | Gray cast iron | Cold box core making sand | Less deformation of the core and less veining on the casting |
Automobile castings, precision machinery castings | Copper alloy | Alkaline phenolic resin sand | The mold is easy to pound, the surface quality of the casting is improved, and the sand recovery rate is increased |
Wear-resistant parts | High manganese steel, high chromium steel | Water glass casting sand | The amount of binder is reduced and the sand recovery rate is increased |
