Sandblasting machine is a kind of machine that uses compressed air as the power to form a high-speed jet beam to spray the spray material on the surface of the workpiece to be processed at a high speed, so that the mechanical properties of the outer surface of the workpiece surface are changed. The mobile sandblasting equipment is suitable for cleaning the rough surface of forging castings, stamping parts and machining parts, for spraying, pretreatment before electroplating, and strengthening the surface of light decoration parts. The automatic sandblasting machine is especially suitable for small and medium-sized parts. produce.
How to choose a sandblasting machine?
1. It depends on the size of the workpiece to choose box sandblasting machine, mobile sandblasting machine and automatic sandblasting machine.
2. It depends on the shape of the product to choose the specifications of the sandblasting machine. Generally, the specifications of the sandblasting machine below one meter are fixed. Especially large ones should be customized or open.
3. The degree of requirements on the product surface depends on whether it is dry spray or wet spray. If it is dry spray, the choice of abrasive is many. Wet spray is generally glass sand.
4. Some parts of the sandblasting machine should be familiar with sandblasting guns and sandblasting gloves, which are often changed because sandblasting is actually very worn.
The function of automatic sandblasting machine:
1. Sandblasting equipment is used for cleaning the surface of workpieces. Sandblasting equipment can be used as a corrosion layer on metal, residual salt and oxide layer on the surface of heat-treated parts, oxide layer on the surface of rolled parts, oxide layer on the surface of forging parts, and surface of welded parts. The oxide layer, the molding sand and oxide layer on the surface of the casting, and the adhesion layer on the surface of the machined part reveal the nature of the matrix.
2. Sand blaster machine is used for the pretreatment of the workpiece surface before coating.portable shotblasting machine can be used as the pretreatment process of various electroplating processes, brush plating processes, spraying processes and bonding processes to obtain active surface enhancement coatings, coatings and Adhesion between bonding parts.
3. Sandblasting equipment can change the physical and mechanical properties of the workpiece. Sandblasting equipment can change the surface stress state of the workpiece. Improve the lubrication conditions of the mating part. Reduce the noise during the movement of the mating part. Harden the surface of the workpiece. Improve the wear resistance and fatigue strength of the part. .
4. Sandblasting equipment is used for the finishing of the surface of the workpiece. Sandblasting equipment can change the surface roughness of the workpiece to produce a matt or diffusely reflective surface of the workpiece to achieve the purpose of finishing.
Advantages of sandblasting machine
1. The dimensional accuracy of the metal parts of the sandblasting equipment will not change.
2. The surface of the part is not contaminated. The abrasive will not chemically react with the material of the part.
3. The sandblasting equipment can easily handle the difficult-to-contact parts such as grooves and pits. A variety of abrasives can be selected for use.
4. The substantial reduction in processing costs is mainly reflected in the improvement of the work efficiency of the sandblasting equipment to meet various surface finishing requirements.
5. Low energy consumption and low cost.
6. The sandblasting equipment does not pollute the environment and saves the cost of environmental treatment.
