Low-pressure casting mould sandblasting technology is the crystallization of modern industrial equipment, surface treatment sandblasting machine whether technical solution or equipment manufacturing, is the leading level of development in the industry, international large enterprises and other customers cooperate to buy low-pressure casting mould special sandblasting equipment.

Strict specification for operation of low-pressure mold sandblasting technology:

Mold surfaces that need to be sandblasted after use can be sprayed several times before the remaining formal spray. At this point, the powder quantity and the uniformity of powder distribution can be observed at both ends of the spray chamber. At this time the powder from the gun end within 10cm-15cm along the straight line, in the form of external atomized powder, adsorbed on the surface of the workpiece powder is actually the effect of the atomization of powder, whether the existence of this atomization effect of powder is the control of the distance between the gun and the profile of the baseline.

In addition to the process parameters, we should also pay attention to the necessary details of the sandblasting machine factory:

1, the position of the spray gun.

The spray gun should maintain a certain inclination, biased to the direction of the workpiece running, environmental protection and energy saving sandblasting machine spray gun should be arranged vertically and parallel, the end part should maintain a straight line, there should be no overlap between the spray gun, the position of the upper and lower spray gun powder cover all the workpiece.

2. Control of fluidized air pressure.

The function of fluidized bed is to make use of the action of airflow to make the powder form appropriate fluidized state, feel similar to the liquid flow state, detect the fluidized to reach the full state, the simplest operation is to use the hand or stick to stir the powder, do not feel the existence of resistance. Fluidization convenient powder inhalation pipe, under the action of accelerating wind, produce atomization effect, insufficient pressure or pressure is too large, insufficient fluidization.

3. Powder recovery and reuse.

The powder adsorbed on the profile surface only accounts for about 1/3 of the powder output from the spray gun, and there are more powder scattered in the spray chamber.
