Shot blasting machines are more and more widely used in all walks of life. For example, steel pipe inner and outer wall shot blasting machines can be widely used to remove rust and oxide layers on the inner and outer walls of steel pipes; radiator shot blasting machines are used for cleaning shot blasting and polishing. Radiator; Crawler shot blasting machine is suitable for sand cleaning, rust removal, scale removal and surface strengthening of small castings, forgings, stamping parts, gears, springs, etc. It is especially suitable for cleaning and strengthening parts that are not afraid of collision. So does the aluminum workpiece need to use a shot blasting machine or a sandblasting machine?
Generally, after the processing of aluminum products is completed, there is no smooth and perfect surface, and the oxidation speed is fast. Because the grade of the product needs to be improved, the appearance must be enhanced, so the corresponding surface treatment of the product can achieve the desired effect, and the aluminum product itself. The material is soft and the wear resistance is poor. The sandblasting machine uses compressed air as the power to spray sand and abrasive onto the surface of the workpiece with a high-speed jet beam from a pneumatic source, so that the surface of the workpiece is deformed to obtain a certain degree of cleanliness and roughness , the mechanical properties are changed, and the fatigue resistance of the workpiece is improved; it is also more conducive to the leveling and decoration of the coating, and it can also remove the oxide scale on the surface of the aluminum product. If aluminum products are chemically pickled, it will not only be highly corrosive, but will also be filtered from the perspective of environmental protection, resulting in high environmental damage. Although shot blasting equipment can also achieve this effect, because the material handled by the shot blasting equipment requires high hardness and is not afraid of collisions, aluminum is a material that is easier to wear in the metallic grade, and the pressure resistance level is low. This type of equipment should be selected for surface treatment!
Finally, I hope that when you buy a shot blasting machine or a sandblasting machine, you should not just listen to the introduction of the salesperson, but choose the most suitable equipment according to the needs of your workpieces and castings, so that you can save costs and increase production. effectiveness.
