Sandblasting treatment of die-casting products is a commonly used surface treatment method with broad application prospects.
Sandblasting treatment is the use of high-speed sand particles to impact and rub the surface of die-casting products, thereby removing impurities such as oxide scale, oil stains, rust, etc. on the product surface, while forming a certain roughness on the product surface, increasing the surface adhesion of the product.
Before sandblasting treatment, it is necessary to clean and degrease the die-casting products to ensure the cleanliness of the product surface. Then, based on the material, shape, and surface requirements of the product, select the appropriate sand material and sandblasting equipment. Common sand materials include quartz sand, diamond sand, glass sand, etc., while sandblasting equipment can be divided into dry sandblasting equipment and wet sandblasting equipment.
During sandblasting, it is necessary to control the pressure, angle, and distance of sandblasting. If the sandblasting pressure is too high, it may cause excessive wear and even deformation of the product surface; If the sandblasting angle is not appropriate, it may result in uneven sandblasting effect on the surface of the product; If the sandblasting distance is too far or too close, it may affect the efficiency and effectiveness of sandblasting. Therefore, it is necessary to adjust the sandblasting parameters reasonably according to the actual situation to achieve the best sandblasting effect.
Sandblasting treatment can not only improve the appearance quality of products, but also enhance their corrosion resistance and wear resistance. The surface of the die-casting product after sandblasting treatment forms a certain roughness, which is conducive to subsequent coating, electroplating and other treatments. At the same time, it also increases the surface hardness and wear resistance of the product, and improves its service life.
In addition, sandblasting treatment also needs to pay attention to environmental issues. The sandblasting process generates a large amount of dust and waste, causing pollution to the environment. Therefore, effective environmental measures need to be taken, such as installing dust removal equipment, recycling sand particles, etc., to reduce the impact on the environment.
Sandblasting treatment is an effective surface treatment method for die-casting products, which can improve the appearance quality, corrosion resistance, and wear resistance of the products, providing a good foundation for the subsequent processing and use of the products.
