Green Sand Castings

Green Sand and a amount of water are used as the main adhesive of molding sand. After making sand mold, it is directly combined and poured in wet state. Wet mold casting has a long history and is widely used. The strength of wet sand mold depends on the clay slurry formed by mixing clay and water in a certain proportion. Once the sand mold is mixed well, it has certain strength. After being pounded into the sand mold, it can meet the requirements of mold closing and pouring. Therefore, the amount of clay and moisture in molding sand are very important process factors.

Resin casting

Resin sand casting is a new process with nearly no allowance and casting molding. This process does not need mold taking, parting surface and sand core, so the casting has no flash, burr and draft angle, and reduces the dimensional error caused by the combination of mold core. The surface roughness of castings can reach ra3.2 to 12.5 μ m; The dimensional accuracy of castings can reach CT7 to 9; The machining allowance is mostly 1.5 to 2mm, which can greatly reduce the cost of machining. Compared with the traditional sand casting method, it can reduce the machining room by 40% to 50%.

  Flexible design: it provides sufficient freedom for casting structure design. Highly complex castings can be produced through the combination of foam plastic blocks.

There is no sand core in traditional casting, so there will be no uneven casting wall thickness caused by inaccurate size of sand core or improper position of lower core in traditional sand mold casting.

Sand with extremely low moisture content can cause the mold to break. On the other hand, the sand with high moisture content can cause saturation of steam in the mold. Sand grain shape and size likewise influence mold quality, just as the sand’s capacity to withstand high temperature (otherwise called obstinate quality). This can cause the mold to collapse when subjected to extreme pressure.
