Product Brief


The manual sandblasting machine uses compressed air as the power and uses abrasive as the medium. The compressed air flows through the spray gun to form a negative pressure. Equipment for spraying workpieces, which can produce beneficial changes on the surface of the workpiece.

Composition structure

  1. Box body: The box body is one of the main components of the sandblasting machine. The box body is also called the box, and the size of the box is determined according to the size of the product. For example, if your workpiece is 400 long, 200 wide and 300 high, then the box you choose should be at least 600 long, 400 wide and 550 high. Of course, there is no such model on the market. Most manufacturers have box sandblasting machines. Several standard models, this model can be selected. If it is a larger size, such as more than 1 meter, it is generally a non-standard model and needs to be customized. Then, when you choose the cabinet, try to choose the standard, because the price is much lower than the non-standard price.


  2. Dust-removing fan: Some box-type sand blasting machines are equipped with separate dust collectors, some are not necessary; but whether or not with dust collectors, there must be a dust-removing fan. There are two kinds of dust blower discharge methods: the first is placed directly behind the box and a hole is opened behind the box; the second is placed above the cyclone separator, which is a cylinder that separates sand and dust.


  3. Spray gun: the main part of the sandblasting machine, it can be said that there is no sandblasting machine without a spray gun. Most of the box type sandblasting machines use siphon (negative pressure) spray guns: such as general spray guns, KL spray guns, KL (Carle type) spray gun switches on the spray gun, you can save a solenoid valve, but the market is very used Less, less use, the components of the spray gun are sand core, air core, nozzle. The most important and most expensive one is the nozzle.


  4. Solenoid valve: The solenoid valve of the box type sandblasting machine generally adopts the solenoid valve with the interface for 4 points. The main function of the solenoid valve is to switch the gas.


  5. Pressure regulating filter: Some manufacturers do not directly use pressure regulating filter, but divide the pressure regulating filter into pressure regulating valve and filter separately, the effect is the same.
