Aluminum alloy die-casting products, surface treatment is generally: powder (powder coating), paint, oil, oxidation, sandblasting, electroplating, etc.
According to the thickness of the product surface treatment, finish is different to divide.
What Is Sandblasting
It is in the surface of aluminum products sprayed with a layer of fine sand.
The reliability of the connection can be enhanced by enhancing the friction coefficient of the contact face.
Sand has thickness, grain is also very different.
The process of cleaning and coarsening the matrix surface by the impact of high velocity sand flow.
Using compressed air as the power, to form a high-speed jet bundle to spray material (copper ore, quartz sand, emery sand, iron ore, hainan) high-speed jet to need to deal with the workpiece surface, make the appearance on the surface of the workpiece surface appearance or shape change, due to the abrasive impact to the surface and the cutting effect, make the surface of the workpiece for cleanliness and different roughness, the workpiece can improve the mechanical properties of the surface, thus improve the fatigue resistance of the workpiece, increase the adhesion between the coating and its, extend the durability of the coating, but also to the flow of paint and decoration.
Preprocessing Stage
The pre-treatment stage of sandblasting process refers to the treatment of the workpiece surface before it is sprayed and coated with protective layer.
The pre-treatment quality of sandblasting technology affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating.
If the pretreatment is not done well, the corrosion will continue to spread under the coating, making the coating flake off.
After careful cleaning of the surface and general simple cleaning of the workpiece, with the sun method for coating comparison, the life difference can be 4-5 times.
There are many ways to clean surfaces, but the most commonly accepted methods are solvent cleaning, pickling, hand tools, and power tools.
Process Stages
Sandblasting process is to use compressed air to power form a high-speed injection beam, the spraying material, such as high speed jet to need to deal with the surface, the surface appearance change of components, due to the abrasive effect on impact on the surface of the workpiece and cutting, make get some cleanliness and different roughness of workpiece surface, the workpiece can improve the mechanical properties of the surface.
The factory has excellent production equipment, complete testing equipment, strong technical force, sound quality system, stable and reliable quality. Based on the concept of "innovation and integrity", it aims to provide customers with high-quality and low-cost satisfactory services, practice the scientific concept of development, and contribute to the revitalization of the economy, international trade and the development of the international power industry.Aluminum Alloy Casting
