The purified sand is lifted to the sand supply tower by No.2 elevator for packing and modeling(brown fused alumina price). The No.2 elevator sends the treated sand to the distributor, and the distributor transports the sand to the sand supply hopper. The sand hopper adopts the rain type sand adding into the sand box for packing and modeling. In the production line, it is often used to add sand by rain(aluminum oxide grit). The resonance frequency of sand box is very important.

After installation, it is transported to the pouring station by rail for pouring(white alumina). If the vibration process of dry sand causes the resonance of sand box, it will lead to the deformation of pattern cluster. The spiral sand adding method is usually used in the case of small production capacity. The shaking table can not be directly placed under it or sand can be added(synthetic corundum).  The parts such as holes and platforms that cannot be cast directly, and further removing dust.

(cheap black aluminium oxide grains suppliers uae)It is more obvious when the burning amount of dry sand is more than 0.25% ~ 0.50%(pink corundum). After pouring, the sand box is cooled in the process of operation. When the casting is transported to the turning box and the casting is cooled enough to be turned over, it is necessary to turn over the box and take out the casting(emery abrasive). The sand is leaked to the sand treatment place for treatment, and then the next cycle of production is carried out.

The main equipment of the negative pressure system is wet dedusting (filtration of the smoke produced by gasification of EPC foam when pouring molten metal)(silicon carbide abrasive), water ring vacuum pump (negative pressure), negative pressure tank (stabilizing negative pressure), gas water separator (leaving gas and water away), exhaust gas purification (through which exhaust gas is disposed(garnet abrasive), and gas discharged from the air reaches national standard).(cheap black aluminium oxide grains suppliers uae)

In order to determine the exact value of ignition reduction, the mechanized foam pattern is suitable for large quantities of castings with high surface sugar content(green silicon carbide). This method makes foam pattern economical. Manual foam pattern is suitable for low quality castings, such as wear-resistant castings and liners(steel grid). The process plan of EPC includes the selection of molding material, molding method and the determination of pouring position.

(cheap black aluminium oxide grains suppliers uae)In production, it is better to control above 200mmhg(black silicon carbide). Negative pressure can be adjusted by valve to keep it above the minimum limit. In order to determine the best EPC process scheme, the structure of the parts should be analyzed in detail. According to the process and characteristics of lost foam casting(glass bead blasting media suppliers), the process plan should first ensure the casting molding and minimize various casting defects to ensure the quality of castings.

Positive pressure is not allowed(aluminum oxide abrasive). In particular, the process design should consider how to increase the process yield and how to combine the patterns to realize reasonable batch casting, so as to improve the productivity and reduce the cost. The following process parameters shall be determined according to the product drawing(garnet suppliers), material characteristics and structural processability of the parts: the allowance of the machining part of the part.(cheap black aluminium oxide grains suppliers uae)
