Precautions for purchasing sandblasting machines

The sandblasting effect is mainly determined by the part material and sandblasting abrasive. According to the different materials of the parts, the range of sandblasting abrasives can range from strong metal abrasives to soft resin abrasives, and dry sandblasting and liquid sandblasting are also key factors to consider.
1. Compressed air requirements:
Select automated sandblasting production lines, semi-automatic sandblasting equipment, pressure sandblasting machines, and suction sandblasting machines based on processing capabilities.
2. Equipment specifications for determining workpiece size:
Select the cabin size based on the workpiece size to have enough space to complete the processing work.
3. Production efficiency determines the type of equipment:
Determine the capacity of the air compressor according to the equipment specifications to protect its service life.
1、 Function or purpose
1. Cleaning of the workpiece surface
It can be used to treat the rust layer of 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 forged parts, oxide layer on the surface of welded parts, sand and oxide layer on the surface of castings, residual dirt and small burrs on the surface of machined parts, and the surface of old parts, etc., to remove the surface adhesion layer and reveal the true color of the substrate. The surface cleaning quality can reach Sa3 level.
2. Pre treatment of workpiece surface before coating
It can be used as a pre-treatment process for various electroplating processes, brush plating processes, spraying processes, and bonding processes to obtain active surfaces and improve the adhesion between coatings, coatings, and bonding components.
3. Change the physical and mechanical properties of the workpiece
It can change the surface stress state of the workpiece, improve the lubrication conditions of the matched parts, and reduce the noise during the movement of the parts. It can harden the surface of the workpiece, improve the wear resistance and fatigue strength of the parts.
4. Surface finishing of the workpiece
The surface roughness Ra value of the workpiece can be changed. A workpiece surface that can generate matte or diffuse reflection to achieve the purpose of polishing processing.
