Sandblasting Polishing: Efficient and Precise Polishing Technology

What is Sandblasting Polishing?

Sandblasting Polishing is a process that utilizes high-speed ejected sand particles (such as fine sand, glass beads) to clean, smooth, or remove irregularities from the surface of materials. This technique is applicable to various materials, including metals, plastics, and glass, and is widely used in industrial manufacturing, decorative design, and maintenance.

Features and Advantages of Sandblasting Polishing

The core technology of Sandblasting Polishing lies in using multi-cone self-adhesive abrasive materials, known as Multi Cone (composite abrasive particles). These abrasive particles, made from plastic rubber fibers and porous ceramics, offer high elasticity and strong self-adhesion, effectively adhering to abrasives (such as diamond powder) to form physical and chemical adhesion.

When these elastic abrasive particles are ejected at high speed onto the surface of a workpiece through sandblasting polishing equipment, they impact the surface at an appropriate angle (30° to 60°), causing deformation and ensuring uniform friction of the diamond powder across the surface. This achieves high-efficiency polishing. Additionally, due to the elasticity of the abrasive particles, they glide along the contours of the workpiece without affecting its precision, allowing for rapid polishing and grinding of irregularly shaped objects.

Applications of Sandblasting and Polishing

1. Metal Surface Treatment

Enhances the smoothness and cleanliness of metal surfaces.
Provides better adhesion for subsequent electroplating and coating processes.

2. Glass Polishing

Creates a frosted effect to enhance aesthetics.
Cleans glass surfaces, improving transparency and gloss.

3. Engraving and Decoration

Creates intricate engraving patterns on materials like glass and stone.
Offers unique texture designs to enhance product aesthetics.

4. Rust and Contaminant Removal

Removes oxidation layers and rust from metal surfaces.
Eliminates stubborn contaminants, improving durability.

Required Materials and Manufacturing Process

Sandblasting and polishing is a commonly used surface treatment process that achieves polishing or cleaning effects by projecting fine abrasive particles at high speed onto the surface of an object. This technique is typically applied to metals, glass, plastics, and other materials to enhance appearance or improve performance.

Required Materials:

Base Materials: Metals (such as aluminum, stainless steel, copper), glass, plastics, ceramics, etc.
Abrasives: Common abrasives include steel beads, quartz sand, and glass beads. Choosing the right abrasive size and material affects polishing results.
Equipment: Sandblasting machines, typically including a compressed air source, sandblasting gun, sandblasting chamber, or control system.

Manufacturing Process:

Preparation:
- Prepare the object for sandblasting.
- Select the appropriate abrasive material and grain size based on requirements, which will affect the smoothness of the surface finish.
- Set the working pressure of the sandblasting machine according to the hardness of the base material.

Choosing the Right Abrasive Material and Pressure

To achieve the best polishing results, selecting the appropriate abrasive material and blast pressure is crucial.

Fine sand and glass beads are suitable for mild polishing and cleaning tasks, such as glass frosting or metal gloss finishing.
Steel grit and aluminum oxide are ideal for more aggressive rust removal and deep polishing.
Pressure control should be adjusted according to the material to prevent surface damage from excessive force.

Conclusion

Sandblasting and polishing is an efficient and precise surface treatment technology applicable to various industrial and decorative uses. By selecting the right process and adjusting the equipment properly, it enhances surface quality and optimizes subsequent processing effects. If you’re looking for the best way to improve product texture and durability, sandblasting and polishing is an ideal choice.
