The Development Trend of Dalian Shot Blasting Processing

Dalian shot blasting is a surface treatment technology that uses tools such as high-speed rotating cutting brushes of shot blasting machines to remove oxide films, rust surfaces, stains, and pits from metal surfaces, in order to achieve the goal of rust removal, corrosion removal, and enhancing the flatness and roughness of metal surfaces. Shot blasting can not only treat metal surfaces, but also surfaces of non-metallic materials such as glass, stone, ceramics, etc.

The principle of shot blasting processing is to use high-pressure airflow to drive the rapid movement of cast iron sand or steel shot, which is then projected onto the surface of the treated object to remove surface defects and oxide layers. At the same time, it can also form a certain thickness of metal surface on the surface of the object. The principle of shot blasting is to use impact and peeling forces to achieve surface cleaning and form a metal surface.

The Development Trend of Dalian Shot Blasting Processing

1. New shot blasting materials: With the development of technology, new types of shot blasting materials are constantly emerging, such as graphene, carbon fiber, and other materials. These materials have advantages such as lightweight, high strength, and high thermal conductivity, which can better meet the needs of different industries for shot blasting materials.

2. New shot blasting equipment: Currently, most of the shot blasting equipment on the market is still traditional mechanical ball shot blasting machines. With the continuous development of technology, new types of equipment such as airflow spraying method, wet shot blasting machine, and laser shot blasting will gradually be introduced to the market.

3. New shot blasting technology: Currently, traditional shot blasting technology is no longer able to meet the development needs of the industry. In the future, shot blasting processing technology will become more intelligent, automated, and integrated, ensuring the competitiveness of the industry market.

Compared to other surface treatment technologies, shot blasting has higher processing efficiency and lower cost. The power consumption of the shot blasting machine is relatively low, and the number of treatments processed in one process is also relatively large, which can complete a large amount of metal surface treatment work in a short time. Moreover, the abrasive used in the shot blasting machine is relatively cheap and can be recycled, resulting in lower production costs.

When the shot blasting wheel rotates at high speed, the shot blasting inside the wheel is thrown away from the surface of the wheel and forms an arc to fly, impacting the surface of the machined part, polishing off the oxide skin, dirt, mortar, and other substances on the surface to achieve the desired roughness. During the flight process, shot blasting will repeatedly impact the surface of the machined part, causing it to produce a certain degree of cold work hardening layer, in order to improve the surface hardness and strength to some extent.
