What materials are suitable for sandblasting in Dalian?

Dalian sandblasting processing is an efficient, flexible, and environmentally friendly method for metal surface treatment, with broad application prospects and market demand. With the development of technology and the advancement of processes, sandblasting technology will become increasingly sophisticated and diversified, bringing more innovation and development opportunities to the metal processing industry.

In the manufacturing process of mechanical parts, sandblasting is used to pre treat the surface of the blank. For example, on the surface of cast parts, defects such as oxide scale and sand holes generated during casting are removed by sandblasting, making the surface of the part flat and clean, providing a good foundation for subsequent mechanical processing (such as turning, milling, etc.). At the same time, the surface roughness after sandblasting increases, which is beneficial for improving the adhesion between coatings (such as paint, electroplating, etc.) and the surface of the parts.

Sandblasting processing is widely used in the field of metal processing. Metal surfaces often have oxides, paint films, rust stains, etc. Sandblasting can effectively remove these surface layers, make the metal surface smooth, increase surface roughness, and improve the adhesion of the metal surface. Metal materials including aluminum, iron, stainless steel, brass, copper, etc. are suitable for sandblasting processing.

Secondly, sandblasting is also commonly used for glass processing. Glass surfaces often have water stains, dirt, and other impurities, which can be removed by sandblasting to make the glass surface more transparent and clear. In addition, sandblasting can also create different texture effects on glass surfaces for decoration or isolation.

Again, plastic materials can also change their surface properties through sandblasting processing. Sandblasting can form fine concave and convex patterns on the surface of plastic, increase its surface roughness, improve adhesion, and make the plastic surface easier to coat or bond.

In addition, ceramics and stone are often subjected to sandblasting processing. These materials usually have a harder surface, and sandblasting on the surface can increase its roughness, improve surface adhesion, and make the coating or bonding more firm.

The principle of processing is to use the high-speed airflow generated by the sandblasting machine to spray sand particles onto the metal surface to be processed, and achieve surface treatment through strong impact and cutting forces. During the processing, sand particles of different sizes and hardness can be selected according to different requirements to achieve different processing effects. The advantages of sandblasting processing are high efficiency, flexibility, and environmental friendliness. It is suitable for both large-area surface treatment and fine carving processing.

The diameter and shape of the nozzle have a significant impact on the speed, particle distribution, and impact force of sandblasting. Smaller caliber nozzles can generate more concentrated and high-speed sandblasting streams, suitable for fine machining and small area processing; Larger diameter nozzles can spray wider sand streams for large-area sandblasting. For example, when sandblasting the cylinder block of a car engine, smaller caliber nozzles may be chosen to handle some delicate parts, while larger caliber nozzles can be used for the large surface area of the cylinder block.
