Surface Cleaning

Post-welding cleaning: Remove welding slag, scale and burrs after body welding to ensure a clean surface before painting and improve paint adhesion.

Casting treatment: Shot blast castings such as engine blocks, crankshafts and gearbox housings to remove residual molding sand and burrs, enhancing surface finish.

Descaling of stamped parts: Eliminate oxide films formed during stamping to provide a good base for subsequent processes (e.g., galvanizing, spraying).

Surface Strengthening

Precision components such as gears and bearings: Shot blasting creates surface compressive stress, reduces fatigue cracks, and extends the service life of parts.

Springs and suspension systems: Strengthening the surface of springs improves corrosion resistance and fatigue resistance, making them adaptable to complex road conditions.

Improving Surface Roughness

Aluminum alloy wheel hub treatment: Shot blasting can optimize the surface texture of wheel hubs, enhance the adhesion of coating layers, and achieve lightweight design simultaneously. 

Composite material pretreatment: Shot blasting is applied to carbon fiber or plastic components to improve surface roughness and enhance bonding strength with adhesives.

Special Applications

Battery shell treatment: Shot blasting is applied to battery aluminum shells to enhance heat dissipation performance and corrosion resistance.

Motor stator/rotor cleaning: Residual impurities from processing are removed to ensure the stability of motor performance.
