Cheap White Corundum Sand Suppliers South Africa

The design of shaking table also affects the compaction effect of foam sand(white corundum). In order to make the foam pattern vaporize in vacuum when it encounters high temperature molten metal instead of burning, the vaporized foam plastic products are pumped out of the box through coating and dry sand during the continuous suction process(steel grid). The accelerometer is used to monitor the vibration of the shaking table to make it in good condition.

The general molding system uses a circular sand box(pink corundum). The sand box is placed in three positions to transmit vibration. The vibration table uses two relatively rotating motors to generate vibration energy. EPC vibration table has one-dimensional, two-dimensional, three-dimensional, two-dimensional, three-dimensional shaking table shape(black silicon carbide). If the vibration of sand dried fruit causes resonance of sand box, it will often cause the deformation of foam pattern clusters.(cheap white corundum sand suppliers south africa)


In the production process, the sand box is required to be firm and reliable, and the shaking table is required to work stably to ensure the reliability of production(white aluminum oxide). The characteristics of commonly used EPC special sand boxes must make the foam pattern replaced by the high temperature metal liquid(aluminum oxide abrasive). The commonly used size of sand box is 750mm × 750mm × 700mm, p750mm round sand box, the height is 1000mm, and the sand capacity is about 900kg.


(cheap white corundum sand suppliers south africa)The center of gravity of the sand box is located in the center, which is slightly lower than half of the height of the sand box(green silicon carbide). So special sandbox should be used. The size of EPC sand box should be as small as possible to reduce the amount of dry sand, reduce the energy consumption of tight sand, inhibit the formation of sand flow, and shorten the filling and compaction time(glass bead blasting media suppliers). There is enough space to arrange the castings in the 360 range with the sprue as the center.


According to this requirement, there are several sand boxes commonly used by EPC(white fused alumina). Single layer bottom empty sandbox: 6-8mm thick steel plate is used to weld when manufacturing sand box, and 4in pipe is used for air exhaust pipe. This kind of sand box has only one side exhaust, and it is suitable for casting foam with small wall thickness. The resonance frequency of sand box is very important(aluminum oxide grit). The sand box is usually welded by 8 ~ 10 mm thick steel plate.(cheap white corundum sand suppliers south africa)


There are wear-resistant plates on the contact point of the vibration table and mesh holes on the side of the sand box, so that the gas can be easily discharged(brown fused aluminum oxide). If the vacuum is to be pumped during pouring, the sand box should also have a vacuum chamber. The sand box is made of 1.5-2-inch copper pipe with a hole of 6 mm drilled on the pipe with a distance of 30-40 mm(garnet abrasive). The newly generated gas should be rapidly withdrawn by negative pressure.


(cheap white corundum sand suppliers south africa)In short, the size and shape of the sand box is determined by the size and size of the casting(black corundum), that is, the size and shape of the casting is the premise of designing and manufacturing the sand box. Four to five pipes are arranged. At the outlet end, a steel pipe larger than the diameter of those pipes is used to weld them on it at equal distance(garnet suppliers), and a 2 in × 60 mm long exhaust pipe at one end is welded from the middle of the pipe to the outside of the box.
