What is the difference between Dalian sandblasting and mechanical polishing?

Sandblasting is a common surface treatment process widely used in the processing of metal products, glass products, and plastic products. Through reasonable process flow and operation methods, the quality and aesthetics of the workpiece surface can be effectively improved. Sandblasting not only increases the added value of the product, but also meets the consumer's demand for the appearance quality of the product.

Sandblasting can be applied to the processing of various materials, such as metals, plastics, ceramics, glass, etc. In metal processing, sandblasting can remove surface oxides, oil stains, and scratches, improving the quality and appearance of metal parts. In plastic processing, sandblasting can increase surface roughness and improve the adhesion of coatings. In ceramic and glass processing, sandblasting can create various textures and effects, increasing artistic and decorative effects.

What is the difference between Dalian sandblasting and mechanical polishing?

Sandblasting is a method of impacting the surface of an object through high-speed blasting of sand particles or other abrasives. During sandblasting, sand particles will impact the surface of an object at high speed, thereby removing oxide layers, dirt, attachments, or rough parts from the surface. Sandblasting processing has the characteristics of simplicity, high efficiency, and low cost, and is widely used for surface treatment of materials such as metals, wood, and plastics. Sandblasting is suitable for removing surface roughness and enhancing adhesion.

Mechanical polishing is a method of grinding the surface of an object using mechanical equipment and abrasives. Mechanical polishing utilizes different grinding tools and particle sizes to continuously grind, scratch, and friction the surface of an object, making it smooth and removing surface defects and uneven parts. During the mechanical polishing process, the speed, pressure, and type of abrasive of the grinding tool can be adjusted to achieve different grinding effects. Mechanical polishing is suitable for improving the surface smoothness of objects, increasing reflectivity, and improving appearance.

In terms of technology, there are some differences in the equipment and working principles used in sandblasting and mechanical polishing. Sandblasting processing usually uses sandblasting machines and sandblasting chambers. The sandblasting machine uses compressed air to spray sand particles or other abrasives onto the surface of the object, and the impact force between the sand particles and the surface of the object will remove impurities from the surface. The equipment used in mechanical polishing includes abrasive belt polishing machines, polishing wheels, brushing machines, etc., which achieve the grinding effect through the rotation of mechanical equipment and the friction of grinding tools. Sandblasting focuses more on material removal and surface treatment, while mechanical polishing focuses on improving surface smoothness and appearance.

The process of implementing sandblasting processing generally includes preparation work, sand material selection, sandblasting processing, and post-processing. Firstly, it is necessary to clean and remove rust on the workpiece to be processed, ensuring that its surface is clean and flat. Then, select the appropriate sand material based on the material and requirements of the workpiece. Commonly used sand materials include silica sand, glass beads, and aluminum oxide sand. Next, place the sand material into the sandblasting machine and connect compressed air to the sandblasting machine.
