High pressure water to remove sand

Basic principle and Characteristics of high pressure water sand cleaning Using high pressure water output from high pressure pump, 10~40MPa is transported through the pipeline to the nozzle of the spray gun to form high pressure jet, which is shot to the shell and core of the casting surface for sand cleaning.

The characteristics of high-pressure water cleaning are as follows:

1) Without damaging the casting, the original clear contour and surface roughness of the precision casting can be completely maintained.

2) High production efficiency and good cleaning effect; Narrow grooves, inlets and bent holes in the casting can be cleaned.

3) Good working conditions, wet operation, no dust hazards.

4) It is economical and convenient for the recycling of old sand, and the used water can be reused only after precipitation treatment.

High pressure hydraulic sand cleaning has been widely used in investment casting. Especially for aluminum alloy castings, high pressure hydraulic sand cleaning has become the preferred method. This is because the surface of aluminum alloy castings is easily damaged by vibration, shot blasting and sand blasting, and the corrosion of castings is easily caused by chemical cleaning.
