Sandblasting Technology – Surface Treatment Solutions
Overview of Sandblasting Technology
Sandblasting is a widely used surface treatment process for metal components, applied for cleaning, surface roughening, oxide layer removal, and surface strengthening. The process works by propelling abrasive particles at high speed onto the component’s surface. The impact removes impurities, burrs, rust, and scale while also increasing surface roughness to improve adhesion for subsequent coatings.
At Nanpi Xingye, sandblasting is a fundamental finishing process in the production of custom metal components. It is suitable for a wide range of metal materials, including stamped parts, aluminum alloy components, steel, and sheet metal, ensuring a high-quality, uniform surface finish that supports downstream treatments such as painting, powder coating, or anodizing.

Typical Sandblasting Process Steps
Abrasive Selection: Choose suitable abrasive particles according to material type and surface requirements.Common abrasives include steel grit, steel shot, sand, ceramic beads,glass beads, and bauxite.
Machine Setup: Configure air pressure, nozzle diameter, spray angle, and exposure time based on process requirements.
Blasting Operation: Propel abrasive particles at high velocity to the workpiece surface, removing defects,oxidation, and residues while achieving desired surface cleanliness or roughness.
Surface Inspection and Cleaning:After blasting, inspect for residual flaws, contaminants, or missed areas,then clean the surface to prepare for subsequent processing.
Common Sandblasting Techniques
Dry Sandblasting: Direct use of dry abrasives; suitable for surface cleaning, roughening, and deburring on most metals.
Wet Sandblasting: Abrasives mixed with water or other liquids; reduces heat buildup and surface contamination,ideal for delicate or heat-sensitive materials.
Glass Bead Blasting: Provides fine,uniform finishes for precision parts, often used before decorative coatings.
Steel Grit Sandblasting: Removes oxides, rust, welding residues; suitable for steel and alloy surfaces.
Ceramic Abrasive Blasting: Ensures uniform roughness for precision metal parts, widely used in electronics and delicate components.
