Malfunctions and Solutions of Mold Sandblasting Machine

　Many customers often encounter many problems when using sandblasting machines, so let's learn about the mold sandblasting machine faults and solutions together!

Mold sand blasting machine fault and solution:

1. Less sand production, or even no sand production. The sand in the sand storage bucket is used up. Turn off the gas and slowly add the appropriate sand.

2. The sandblasting gun of the mold sandblasting machine may be blocked. When you stop breathing, go to the nozzle and look for foreign objects. It can also cause blockage, so the compressed air must be dry.

3. Sand blast pipe is blocked. The pipe was clogged with stolen goods. After the air is cut off, remove the nozzle first, and then open the sand blasting machine to blow out the foreign body with the high pressure air of the air compressor; Remove piping and clean or replace with new piping.

4. The mold sandblasting machine is not sandable due to the combination of moisture. This is to clean the nozzle of the airbrush, pour out the sandblasting abrasive, dry it and strain it through a sieve.

5. The large amount of water generated by the compressed air of the air compressor supporting the sand blasting machine will not only cause the sand to be damp, but also cause the sand to be wet on the wall of the sand blasting pipe, and gradually block the pipe, so this kind of thing should be avoided and equipped with a dryer.

6. The sand blasting material has no filter screen, resulting in large foreign bodies or uneven sand particles entering the sand valve. To this end, the thrust device is closed first, and the sand regulating valve is fully opened. Or remove the caked sand; If not, can only remove the sand control device, sand, and then recover the sand control device; The sand is then filtered before being added.

7. If too much sand is added at a time, too much sand will also cause blockage and cannot be pressurized to suck sand; So when adding sand, we must pay attention to the right amount and add slowly.

When choosing a mold sandblasting machine, users mainly consider whether to choose manual sandblasting machine or automatic sandblasting machine from the aspects of labor, efficiency, power consumption, product characteristics and so on. When the user has fewer products and the workpiece size is small, the environmental protection box type manual sandblasting machine can be selected; When the user has more products and larger workpiece size, such as containers and large steel structural parts, you can choose the open mobile manual sandblasting machine. Sandblasting machine, when the user's products are not very large, the number of more, according to the shipping requirements of the product every day and the related labor costs, power costs and other costs, choose the automatic sandblasting machine or more manual sandblasting machine.

In addition, in the choice of mold sandblasting machine, it is also necessary to consider whether the structure of the product is suitable for the sandblasting process of this kind of sandblasting machine. General manual sandblasting machine as long as the workpiece is not larger than the size of the manual sandblasting machine working window can be sprayed. Different styles of automatic sandblasting machines have different requirements for the workpiece, such as: plane conveying automatic sandblasting machine is suitable for automatic sandblasting of flat products, such as: glass, flat stainless steel parts, aluminum and other similar products, the number of spray guns is recommended to decide according to the size of the product. If the product is too large and the number of spray guns is too small, the spray will be uneven. As a surface treatment equipment, sand blasting machine has a wide range of applications in industrial production. Can remove casting billet, forging, stamping, welding, heat treatment and machining parts, glass three-dimensional engraving, spraying and other processes of oxide skin, residue, burr.

The above is the mold sand blasting machine fault and solution, if you need to know more about the relevant knowledge, please feel free to contact us!
