Surface Pretreatment

Application objects: large structural parts such as fuselage frames, lifting arms, buckets, pins, etc. of excavators, loaders, bulldozers, etc.

effect: 

Rust and scale removal: removal of oxide layers, rust and residual impurities on the surface after welding, forging or heat treatment. 

Roughness optimization: uniform roughness is formed through steel shot impact, which enhances the adhesion of subsequent coating (such as painting and plastic spraying) and extends the anti-corrosion period. 

Stress relief: Relieve residual stress generated during welding or processing, reducing the risk of deformation.

Surface Strengthening

Application objects: gearbox gears, drive shafts, bearings and other precision transmission parts. 

Effect: 

Surface strengthening: Shot blasting creates compressive stress on the surface, improving fatigue strength and wear resistance, and extending component life. 

Deburring and finishing: remove burrs and micro defects after processing, improve surface finish and reduce friction loss.

Improve surface roughness

Application objects: Crankshaft, connecting rod, cylinder block and other core components of the engine.

Effect: 

Strengthening and cleaning: Shot blasting can refine the grains, improve the strength of the material, and remove the sand and oil residues from casting or processing. 

Eliminate stress concentrations: Reduce the risk of fatigue cracks, especially for components that operate at high speeds.

Remanufacturing and repair

Application scenarios: Refurbishment of old equipment and repair of key components (such as pins and gears).

Effect: 

Old coating stripping: Quickly remove old paint or plating to facilitate repainting.

Damage detection: After shot blasting, surface cracks, wear and other defects can be visually inspected.
