What is Sandblasting machine?

 Sandblasting machine uses compressed air as power to form a high-speed jet beam to spray materials (shot peened glass beads, steel shot, steel sand, quartz sand, emery, iron sand, sea sand) on the surface of the workpiece to be processed at high speed to make the workpiece The mechanical properties of the outer surface of the surface change. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, thereby improving the workpiece Fatigue resistance increases the adhesion between it and the coating, prolongs the durability of the coating film, is also conducive to the leveling and decoration of the coating, removes impurities, variegated colors and oxide layers on the surface, and makes the medium The surface roughening can make the residual stress on the surface of the substrate and increase the surface hardness of the substrate.

Choose the method of portable sand blasting machine:

1. Depending on the size of the workpiece, choose box sandblasting machine, mobile sandblasting equipment, and automatic sandblasting machine;

2. Depending on the shape of the product, choose the specifications of the sand blasting machine. Generally, there are fixed specifications for the one-meter or less, and the especially large ones should be customized or open.

3. The degree of product surface requirements depends on whether it is dry spray or wet spray. If it is dry spray, there are many options for abrasives, and wet spray is generally glass sand.

4. Some accessories of sandblasting machine should be familiar with. Sandblasting gun and sandblasting gloves are things that need to be changed frequently, because sandblasting is actually very worn out.

The choice of sandblasting machine?

Generally speaking, the blasting effect is mainly determined by the blasting medium (abrasive). The range can range from strong metallic abrasives to soft resin abrasives. At the same time, dry blasting and wet blasting are also important considerations. Customers can bring workpiece samples to determine.

According to the processing capacity, choose automatic sandblasting production line, semi-automatic sandblasting equipment, pressure sandblasting machine, and general pressure sandblasting machine. Choose the size of the cabin according to the size of the workpiece so that there is enough space to complete the processing work. Determine the air compressor capacity according to the equipment specifications, and leave a 20% margin to protect the service life of the air compressor. When you choose sandblasting equipment, you should consider the professional knowledge and experience of the seller or manufacturer. A good supplier can provide you with effective guidance and after-sales service.

Features of automatic sandblaster:

1. The metal parts of the sandblasting machine are basically not damaged, and the dimensional accuracy will not change;

2. The surface of the part is not contaminated, and the abrasive will not chemically react with the material of the part;

3. The portable sand blasting machine can easily handle grooves, cavities and other difficult-to-contact parts, and a variety of abrasives can be selected for use;

4. The processing cost is greatly reduced, which is mainly reflected in the improvement of the work efficiency of the sandblasting machine, which can meet various surface finishing requirements;

5. Low energy consumption and low cost;

6. The sandblasting machine does not pollute the environment and saves the cost of environmental treatment.

Application scope of mobile sandblasting equipment:

Sandblasting machine is a new type of surface treatment processing equipment, which is widely used in machinery, locks, electronic clocks, glasses, hardware tools, molds, glass, ceramics, handicrafts, medical equipment and other industries. It can remove casting blanks, forging, stamping, welding, Heat treatment and machined parts of oxide scale, residue and burrs, glass three-dimensional carving, spraying and other processes. It has the beautiful effect of imitating alloy on the surface of ornaments such as clocks, glasses and so on. The portable sand blasting machine is currently the ideal surface processing and treatment equipment.
